1.3 Intended use
The CO2 laser, C-LAS Model, is an easy-to-transport table laser console made of machined aluminum and
optics for the reflection of CO2 laser beams. It is a carbon dioxide laser which emits laser light at 10.6 microns
and an RF-excited laser tube, which produces a maximum output of about 30 watts. The laser is designed for
the surgeon for cutting and coagulating tissue at a wound during surgery. The surgeon uses the laser
radiation on tissue through a handpiece with or without inserts or lenses. The laser radiation can further be
adjusted and controlled by a micromanipulator.
The CO2 laser, C-LAS model, is intended to be used by surgeons for cutting soft tissue and ablating tissue in
the following areas:
General Medicine Jaw Aesthetic & Plastic Surgery
Dermatology Neurology
ENT Dental & Maxillofacial
Gynecology Ophthalmology
Contraindications exist in case the user has not been trained on how to use the laser and is not able to
correctly control the emission while guiding the laser beam. The basic requirement being that the laser is only
used in case the user does have sufficient experience either gained in surgeries or following comprehensive
training by another experienced surgeon on a model tissue such as animal or comparable tissue.
Contraindications exist in the following cases: if the laser is used in an environment where gases may ignite
or explode e.g. when oxygen is used during the anesthesia of patients. It would be dangerous if the laser
beam hit an oxygen-saturated region. Each situation involving the risk of uncontrolled irradiation of third
parties shall be avoided.
Another contraindication exists if the need to use the laser is not high and alternatives are given, and the
treatment zone is inflammated. The effect of laser radiation results in the transfer of heat to the tissue, which
may aggravate the inflammation.
In general, no hard tissue such as bones should be treated.
The use of the laser beam in the vicinity of temperature-sensitive areas (such as nerves in neurosurgery)
should also be avoided.

2 Theory and Technical Structure of a CO2 Laser
Laser is an acronym adopted for everyday use
Light Amplification by Stimulated Emission of Radiation
Laser light energy is different from standard optical energy as it has the following properties:
Highly coherent; All of the light energy is travelling in the same phase
Monochromatic; It consists of a narrowband range of wavelengths
Directional; The energy travels in the same direction and does not spread.
All types of lasers consist of three key parts:
Lasing medium; This provides atoms or molecules to allow for the amplification of light.
Excitation source; A means of exciting the atoms or molecules.
Optical resonator; Similar to a resonant circuit this generates and supports stimulated radiation
through continual internal reflection.
Atoms and molecules have different energy levels, when a change to a more excited state occurs, this will,
after time, be followed by a change to a more relaxed state. When the change to a more relaxed state occurs,
the lasing medium releases this stored energy, typically in the form of light (photon), though by-products such
as heat may also be emitted, this needs to be removed from the laser system.
RF energy acts as the excitation source and is supplied to the CO2 gas to change the vibrational state of the
molecule, this supplied energy changes the vibrational state of the molecule, from a lower state to one that is
a higher state i.e. the lasing medium is in an excited state. In the case of the CO2 laser the change to a lower
state of vibrational releases photons at 10.6µm. The period that the gas stays in this excited state is very short,
however this can be influenced. By adding a cavity or optical resonator around the lasing medium, already
existing photons can be used to further increase the supply of photons. Photons are absorbed by those atoms
or molecules in an excited state, this then triggers the release of two photons, each of which have the same
energy, travel in the same direction and have the same phase - these are the unique properties of the laser.
The cavity ensures that this happens many times over to increase the supply of photons and provides a steady
state to give a constant optical output. These photons would typically leave the cavity through a partial mirror
at one end; the optical energy can then be coupled into a hollow core optical fibre or another optical system.
The laser tube is controlled with electronics, which can be adjusted by the user on the control monitor. Output
power, pulse length and width can be controlled individually with the C-LAS laser.

3 Transport / Storage
The CO2 Laser C-LAS is delivered in a special transport packing, which ideally protects the device of
moisture, temperature changes and vibrations.
On-site the C-LAS should only be moved on the designated C-LAS cart which is damped in particular.
While the C-LAS is not used it should always be covered by the supplied dust cover sleeve.
The device should never be exposed to temperatures below 2° C or over 40° C.
The C-Las has to be protected against water and moisture!

4 Installation
4.1 Installation Site
Prior to delivery, the user needs to make sure a suitable location has been prepared for installation.
The laser device should be installed at an easily accessible place. The C-LAS Laser should be installed at
an accessible place - neither too close to a heater nor next to a sink. The laser should not be operated close
to a heater as its air-cooling system works best when the ambient temperature does not exceed 21°C.
Higher ambient temperature may result in shorter working times as the device will switch off earlier to prevent
overheating.
If the ambient temperature is too low (below 10°C), the device cannot be started. Thus, any condensation
which may occur on its internal optics is avoided as this might cause a permanent damage.
All control elements need to be readily accessible. The fibers at the front require sufficient space to avoid
accidental bending. The air humidity in the treatment room should be monitored and kept below 75%.
4.2 Room Requirements
Legislation imposes the following requirements with regards to any room in which a class 4 laser device
(according to DIN EN 60825-1) is operated.
4.2.1 Marking Access Doors
All access doors shall be clearly marked to prevent any outside person from entering as this might be
hazardous.
Please attach laser warning labels (triangle with laser symbol) and the wavelength
identification at each access door.
Please mount a warning lamp above each access door. It should always light up when the
laser is in operation.
This helps to prevent anybody from entering the room without protective goggles.
Please store the protective laser goggles in an easily accessible place at the entrance.
4.2.2 Window Shielding
Please make sure no laser radiation can exit the room. In particular, the window should be protected with
suitable materials. For further information please call your contact at A.R.C. Laser GmbH at any time.
4.2.3 Shielding Reflecting Surfaces
To avoid any danger caused by reflected direct or scattered radiation, there should not be any reflecting
surfaces in the room. Such surfaces may be
mirrors
pictures with front glass
chrome surfaces
windows
Such surfaces should either be removed or suspended or matted. Please use matted, non-reflecting, non-
flammable instruments and materials only in the area around the laser fiber port.
4.3 Electrical Connection
The laser is operated with an internal power supply of 100 V to 240 V AC. The supplied power cord complies
with the specifications for medical use.
The supply voltage for the laser is as follows:
110-240 V / AC with an input current of 5A at 230V or 10A at 110V.

Manual C-LAS
03 2018
File:User-Manual_C-LAS-II_EN_03_2018_0123.docx 13
Each voltage between these voltages can be used without causing damage to the device. A switching power
supply is used in order to achieve an independent input power. The rated power is 650 VA. The input to the
C-LAS is independent of the mains voltage.
The power supply produces 2 voltages:
For the RF power supply
For the electronic system
The electronic power supply is controlled independently. It is important to insert the appropriate fuse with the
existing voltage.
A T T E N T I O N !
Different input voltages require different security levels.
230 V 2x T 5 A
115 V 2x T 10 A
Please do not use any excessive fuses to operate the laser!
4.4 Dispatching and Unpacking the Device
In the event where unpacking and installing the device is performed by an authorized technician of A.R.C.
Laser GmbH, the technician – having installed and properly connected the device - will put the device into
operation and explain its function. All functions and security features will be discussed and demonstrated.
In the event that the user unpacked and installed the device:
You will get accompanying documents with your laser system. We kindly request you to fill these documents
out and send them back to A.R.C. Laser GmbH. The local A.R.C. Laser representatives will take care outside
Germany.
In the event where the device is transported to you via courier delivery service, please make sure that the
carrying case has arrived undamaged – before the arrival of the service technician. Any damage to the
packaging should immediately be reported to A.R.C. Laser GmbH and will be reported to the carrier.

Class 4 of this standard describes high-energy laser devices. This requires special measures to be taken
before operating the laser to ensure the safe and proper operation of this device. Particular emphasis must
be placed on protecting the eyes and the skin of the operator, the patient and the accompanying persons.
Therefore, please make sure you wear protective goggles and take appropriate precautions for clothing.
Please pay special attention to protecting yourself against reflecting light. Furthermore, do not store any
flammable materials in the room in which the laser is operated.
Although the following explanations may be very detailed, they do no claim to be complete. Hence, all users
of the laser devices should enclose regulations that become accessible over time with the device and inform
the staff accordingly. We refer in particular to the brochure "Operation of Laser Devices and Accident
Prevention Regulations for Laser Radiation", which can be obtained from us. Additionally, regulations can be
retrieved by the TÜV of the individual countries. Should the device be operated outside Germany, you can
also retrieve regulations from the American National Standard ANSI Z136.3-1996 offices "American National
Standard for the Safe Use of Lasers in Health Care Facilities" ANSI Z136.1-1995 and "American National
Standard for the Use of Lasers". Should you have any further questions, please contact our technicians or
ask our office for information about the management system.
5.2 Eye Protection
A T T E N T I O N !
Never look directly into the laser beam or into the light reflected by the laser beam. Never look directly into
the exit of the fiber optics or into the exit of a laser optics (e.g. hand piece) as this will definitely cause
damage to your retina.
As a security measure against direct or indirect laser radiation within the laser chamber, it is necessary – and
also clearly defined by the accident prevention regulations for laser radiation - that all people in the room
wear protective goggles.
Eye protection for both the operator and the patient must stop laser radiation from all directions.
When using the C-LAS (invisible light) only such laser safety glasses shall be used, which are designed for
the wavelength and which bear the CE mark and the protection category DL4 respectively LB4 for 10,600
nm. Protective goggles complying with the authorization can be obtained from A.R.C. Laser GmbH.
For repeat orders please refer to A.R.C. Laser GmbH, indicating the wavelength or the item number of the
protective goggles. Please contact us for any further questions regarding the protective goggles and how to
wear them.
There are various types of protective goggles that also allow spectacle wearers to wear goggles tight on all
sides. In particular scattered radiation which does not directly get to the eye from the front may present risks
resulting from internal reflections on the glasses. Therefore, we encourage you to wear the protective
goggles, which also guarantee full protection on the side panels.
Make sure the treatment room cannot be opened from outside during the treatment. In addition, a warning
light should be installed from outside. When the laser is being operated, this warning light must be turned on.
In addition, sufficient protective goggles should be available in the room to eventually provide escorts with
protective goggles. For the patient, a customized eye protection must be guaranteed.

visual warning system to indicate that the laser is in the "Ready" mode and in operation.
One main switch to control the radiation exposure to the patient.
A door lock switch i.e. a locking connector switch which can be connected with the door. When the
door is opened, the device switches off immediately; however, we recommend to manually lock the
door from inside to ensure no one can enter accidentally.
5.3 Respiratory Protection
While operating the laser, limit the access to the area to such individuals who have been trained in laser
safety.
Avoid operating the laser in a darkened environment.
Do not use the laser in the presence of flammable, explosive or volatile substances such as alcohol,
benzene or ether.
Plumes may arise in certain applications of the C-LAS laser. In this case, please use a suitable
smoke evacuator. A.R.C. Laser will assist you in selecting an appropriate device.
A T T E N T I O N:
Plumes may contain contaminated particles!
5.4 Electrical Protection
Never remove the housing parts of the laser as this may result in the immediate destruction of the device.
Work must only be performed by authorized personnel of A.R.C. Laser GmbH.
When the laser device is turned on, there is a voltage of 48 V in the laser head. The laser head itself contains
no user-serviceable parts or optics. The room in which the laser is operated should be kept dry. If you have
any cleaning work, in which water is used, make sure the soil is dry before operating the laser device.
A T T E N T I O N !
Never work with the laser when you notice a defect on the device.
A T T E N T I O N !
Never work with the laser device when you identify open wires or cables caused by improper treatment of
the plugs.

5.5 Explosion and Fire Hazard
A T T E N T I O N
Do not work with the laser near easily flammable anesthetics, easily flammable solvents, or other flammable
materials. In particular, combustible plastic or paper parts should be removed from the work area of the
laser. Focusing on easily flammable and absorbing materials for the green / blue wavelengths may result in
an inflammation of the same.
While working, make sure that the laser is switched from the READY mode to the STAND BY mode in case
the treatment is interrupted. This ensures that no laser beam is triggered even if you inadvertently step on the
foot switch.
5.6 Protection against Undesired Radiation
Never touch directly into the laser beam or focus the laser beam on easily flammable materials as this may
result in burns to the hand or ignition of the material.
The foot switch that triggers the pulse should never be outside the range of the attending surgeon. It is
forbidden for any person other than the attending surgeon to release the foot switch.
In operating rooms where there are multiple foot switches, it is particularly important to make sure that the
foot switch of the laser is in your area.
A T T E N T I O N
During the actual treatment, the system is in the „Ready“ mode ". If you interrupt or ask other patients in
during the break, the laser must be returned into the so-called "stand-by" mode. Where breaks last longer
than 1 minute, please press the "Ready" button.
The device must always be turned off when not under supervision to prevent any operation by unauthorized
persons.
Any use of the control or adjustment device other than in the way described may cause hazardous exposure
to radiation.
