1.2 Applications
The WON COSJET ATR S laser system is a flash lamp pumped, Q-Switched
Nd:YAG(Neodymium-doped Yttrium Aluminum Garnet) laser is near infrared (1064 nm) and
visible (532 nm) pulsed laser output energy are used in these applications. This beam is directed
to the treatment zone by means of the Articulated arm and specially designed handpiece. When
the laser beam contacts human tissue, the energy in the beam is absorbed surrounding skin
structures. The physician can optimize the effect for different applications by controlling the
energy of the laser pulse and the spot size of the treatment beam.
1.2.1 Side effect
Skin lightening (depigmentation): Some dark skinned individuals can develop fading of the skin
color. This complication is temporary and usually resolves within 10-14 weeks. However, there
are times when the complication is permanent.
Skin darkening (hyperpigmentation): In fair skinned people, lasers can sometimes cause
darkening of the skin. Over time this fades and recovers; but in some cases a bleaching agent has
to be used to erase the dark color.
Infections: Sometimes an infection can occur at the site of the tattoo removal. The infection may
be superficial and resolves but in some cases, deep skin infections can occur and result in a scar.
Skin Texture: After laser treatment, most individuals will have a rough skin texture. The skin
will feel like it has been scraped. These changes are transient and usually resolve in 1-3 months.
Thick skin usually resolves better than thin skin. The facial skin is more sensitive to texture
changes than skin elsewhere on the body.
Allergic reactions: Rarely when the laser disrupts the ink particles some individuals may have an
allergic type reaction. It is not known why the reaction occurs and to what ink. The skin usually
becomes red, dry and it itchy. Application of topical corticosteroids will suffice.
Ink darkening: When the laser is applied on cosmetic tattoos, it can worsen or darken the color.
This is most likely felt to be due to the heat of the laser reacting with the cosmetic chemicals. The
changes can be permanent. So before a cosmetic tattoo is treated, a brief test is done to look at the
response. Many an individual has had permanent tattooing of their eye liners.
Sun burn: After every laser procedure, a sunburn effect occurs. The skin appears red and fiery in
some cases. This is a normal and transient- it does resolve within a few weeks. Besides keeping
the area clean, there is no need to apply any ointments or creams, except the sunscreen

User Manual
WT-UM-08 (v4.4)
9/55
Miscellaneous: Many of the tattoo dyes are unregulated and their exact contents unknown.
Despite this the, complications of laser are rare. A few individuals do develop thickening of the
skin. This thickening known as granuloma is felt to be due to ink particles embedded in
scavenging cells. The granuloma may be small bump on the skin. When lasers are used near the
eye, hair loss and anatomical distortion of the eye lids have been known to occur
1.2.2 Contraindication
Pregnancy, bleeding disorders; immune deficits; heart, liver, and kidney insufficiency; allergies to
local anesthetics; pacemaker and serious heart rhythm disorders; psychiatric disorders; unstable
motivations; large fat volumes; and obesity.
1.3 System Description
1.3.1 Laser System
The WON COSJET ATR S laser system consists of an Nd:YAG laser head, a power supply, a
cooling system, a delivery system and other electrical components. The laser head contains two
Nd:YAG laser medium, and two high-intensity xenon flash lamps enclosed together into the
water cooling housing and two reflected mirrors fixed ,in the special adjustable holders
composed the laser cavity.
To provide energy to the flash lamp, high voltage power supply charges to a storage capacitor.
Then, a trigger pulse applied to the flash lamps causes the capacitor to discharge through the
flash lamps. The resulting flash excites the Nd:YAG laser rod, causing the emission of a pulse of
laser energy.
The electro-optic modulator with a polarizer (Q-switched module) introduced into the cavity
creates the ultra-short (2~40 ns) irradiation pulses. The basic frequency of 1064 nm can be
doubled by a KTP crystal, which can be inserted to a working area. The sealed top metal cover
protects all optical components from dust and humidity and blocks the visible and invisible
scattering light from the laser head.
The system delivers laser energy at a wavelength of 1064 nm and 532nm. The output of the laser
is delivered to the area of treatment through an articulated ARM with a handpiece. A trigger (foot
switch) controls the delivery of pulses. The user selects and sets the treatment parameters and
other functions operated by software on the graphical user interface.
1.3.2 Classifications
Under CDRH regulations in US FDA, the WON COSJET ATR S is classified as a Class Ⅱ
medical device. Under the Medical Device Directive, the WON COSJET ATR S is a Class llb,
non-invasive, active device according to Annex lX of Directive 93/42/EE. Under EN60825-1, the
WON COSJET ATR S laser system safety level is Class 4.

1.3.3 Beam Delivery System
The articulated ARM is to deliver the Nd:YAG laser energy and the diode laser aiming beam to
the skin surface and handpiece as a distal end for radiation is to radiate the treatment laser and
aiming beam. The output of built-in diode laser is a visible low power beam at a wavelength of
650nm. Since the output laser beam is invisible the aiming beam allows the user to see the
surgical area to which the treatment laser will be delivered.
The articulated ARM consists of seven high reflection mirrors mounted at the special joint ARM
freely rotated in different directions. The handpiece with the focusing lens is mounted at the end
of the ARM. The handpiece provides the adjustability of the beam spot size. The spot size of
handpiece is automatically detected by changing the handpiece dial. The articulated arm with
handpiece unit must always be perfectly aligned.

2SAFETY
2.1 General Safety Rules
WARNING
THE ELECTRICAL AND LASER RADIATION HAZARDS PRESENT DURING
SERVICING OF THE WON COSJET ATR S LASER SYSTEM CAN BE
EXTREMELY DANGEROUS IF PROPER SAFETY PRECAUTIONS ARE NOT
TAKEN. CONSEQUENTLY, THE WON COSJET ATR S LASER SYSTEM IS
TO BE SERVICED ONLY BY THOSE QUALIFIED TECHNICIANS WHO
HAVE RECEIVED APPROPRIATE TRAINING, AND WHO ARE FAMILIAR
WITH THE SAFETY CONSIDERATIONS DISCUSSED IN THIS SECTION.
The WON COSJET ATR S laser system has been designed to comply with the requirements of
the EC Directive on Medical Products (93/42/EEC). In accordance with this EC Directive, the
WON COSJETATR S laser system qualifies as a class IIb device.
However, any laser system can cause injury if it is not properly installed, operated, moved or
serviced. The potential hazards associated with the WON COSJET ATR S laser system are:
-Ocular (vision) damage resulting from exposure to direct or reflected laser radiation.
-Electrical shock from contact with electrical components inside the system.
-Physical injury incurred while moving the system.
In handling medical laser devices, observe the relevant national regulations on the prevention of
accidents by laser radiation, as amended. To avoid these hazards, when installing, operating,
moving or servicing the system, always observe the precautions discussed in this section. Our
service technician will assist you in filling it in as part of the startup procedure.
2.2 Laser & Optical Hazards
For fundamental rules on the handling of laser devices, you are referred to the international
standard EN 60825-1. It is complemented by national regulations providing general protection
from dangerous laser radiation. Their purpose is to protect operating personnel and patients
present in medical application.
WARNING
LASER BEAM ENERGY EMITTED BY THE WON COSJET ATR S LASER
SYSTEM LIES IN THE VISIBLE AND INVISIBLE (NEARINFRARED)
REGION OF THE ELECTROMAGNETIC WAVES.
USE ONLY SAFETY GOGGLE THAT IS KNOWN TO HAVE AN OPTICAL
DENSITY OF 6.0 OR GREATER AT 1064 NM AND OPTICAL DENSITY OF 7.0
OR GREATER AT 532 NM, THE WAVELENGTH EMITTED BY THIS LASER
SYSTEM. SAFETY GOGGLE THAT IS DESIGNED FOR USE WITH OTHER
LASER SYSTEMS MAY NOT PROVIDE ADEQUATE PROTECTION.
Lasers are classified in accordance with their potential for danger. The WON COSJET ATR S
laser safety level is class 4.

User Manual
WT-UM-08 (v4.4)
15/55
The laser beam emitted by the WON COSJET ATR S laser system is capable of causing loss of
vision. Laser beam energy emitted by this system lies in the visible and invisible, near-infrared
region of the electromagnetic waves.
Remember this and take precautions to avoid inadvertent exposure. The cornea and lens of the
eye are transparent to the invisible 1064 nm wavelength emitted from this laser, and therefore
will focus the beam directly onto the retina. Such direct impingement of the laser beam on the
retina can result in temporary clouded vision, retinal lesions, long-term scotoma (vision absence
in an isolated area), and long-term photophobia (sensitivity to light).
NOTE
Refer to EN 60825-1.
The beam emitted from the Handpiece is expanding with a full-angle beam divergence. This
means that the spot size enlarges as the distance from the Hand-piece. There is a distance from
the Hand-piece, called the NOHD (Nominal Ocular Hazard Distance), at which the beam is so
big that it is no longer dangerous to the unprotected eye.
Personal eye protection: Everyone present in the laser room during a treatment session must wear
laser safety goggles. Laser safety goggles must perform to specifications defined in the technical
data.
To avoid these vision hazards, everyone within the NOHD where the laser system is operating,
including during service procedures, must wear appropriate eye protection. Such safety goggle,
available from WON TECH, provides adequate protection against reflected or scattered laser
radiation, or inadvertent brief exposure to the laser beam. Laser safety goggle should be stored
away from direct sunlight.
The protective goggle recommended for use with this laser system by all personnel is either
goggles or spectacles (with side shields) that have an optical density of 6.0 or greater at 1064 nm
and an optical density of 7.0 or greater at 532 nm.
WON TECH are appropriate for most patients. Even when wearing protective goggle, looking
directly into the path of the laser beam may cause permanent eye damage.
The laser beam emitted by the WON COSJET ATR S laser system should never be directed at
any part of the body other than the intended site of treatment or testing. Care should be taken to
avoid unintended exposure of any part of the patient or other personnel to the laser beam.
Removal of any of the exterior panels of the laser system cabinet could allow access to hazardous
levels of laser radiation. For this reason, these panels are designed not to be easily removable;
they must not be removed except by authorized, trained service engineer.
Optical Safety Precautions
-Identify the laser room clearly. Post appropriate warning signs in prominent locations at
all entrances to the laser room.
-Cover all windows, portholes, etc. with opaque material to prevent unintended viewing
or laser light escaping from the laser room.

User Manual
WT-UM-08 (v4.4)
16/55
-Restrict entry to the laser room when the WON COSJET ATR S laser system is in
operation. Limit access to the laser room only to those personnel both essential to the
procedure and well trained in laser safety precautions.
-Check the safety before operating the laser and operate in the proper order.
-Make sure that all laser room personnel are familiar with the laser system controls and
know how to shut down the laser system instantly in an emergency.
-Appoint one person to be responsible for the laser system controls during the procedure.
-Laser can cause fatal harm to human, so only trained doctor should use.
-Avoid accidental exposure to the laser beam either directly, or by reflection, by ensuring
that all personnel wear appropriate safety goggle whenever the laser system is on. Verify
that the protective goggle used is known to protect against the wavelengths emitted by
the WON COSJET ATR S laser system.
-Never look directly into the laser beam coming from the laser system, or reflected from
a surface, even when wearing protective goggle.
-Never allow the laser beam to be directed at anything other than the targeted area, the
calibration port or a safe beam stop (used when servicing the system).
-Never permit reflective objects such as jewelry, watches, instruments or mirrors to
intercept the laser beam.
-Specified the parameter values just before the laser operation.
-Do not use the combustible anesthetic gas.
-Check the Stand-by or Ready state before using.
-Never leave the key in an unattended laser system.
2.3 Laser-Induced Risk of Fire
A surface hit by the laser beam will absorb laser energy causing its temperature to rise, regardless
of whether the surface belongs to skin, hair, clothing or other flammable substances.
Operators should take the following precautionary measures, in order to prevent cases of laser-
induced fire:
-Use non-flammable substances for anaesthesia, preparation for treatment, cleaning and
disinfection of instruments.
-Refrain from the use of oxidizing gases such as nitrogen oxide (N2O) or oxygen.
Proceed with particular care when using oxygen. Oxygen increases the intensity and the
scope of fire.

User Manual
WT-UM-08 (v4.4)
17/55
-Keep only a minimum in flammable materials inside the treatment room. Where a
flammable material is required for a given therapy, this material should first be
moistened.
-Keep clothing away from the zone of treatment as much as possible.
-Always keep a small fire extinguisher and water ready for use in the treatment room.
-Some materials like cotton may ignite at high temperatures prevailing during normal use
of the laser if penetrated by oxygen.
-Let solvent constituents of adhesives and flammable solutions used for cleaning or
disinfection evaporate before you apply the laser.
2.4 Electrical and Mechanical Hazards
The WON COSJET ATR S laser system was designed to comply with EN 60601-1-2
EN 60601-1-2 deals with
measurements of unwanted radio frequency emissions generated from a product. Both radiated
emissions (radiated through the air) and conducted emissions (conducted into the AC mains) are
measured.
The WON COSJET ATR S laser system converts and amplifies the AC line voltage to produce
extremely high voltages inside the laser system. These voltages are very dangerous, and possibly
even lethal.
It is possible for high-voltage components to retain a charge after the power supplement has been
turned off, and even after the WON COSJET ATR S laser system has been disconnected from the
line voltage. Therefore, no part of the exterior housing should be removed, except by a trained
and authorized technician.
To prevent the device from moving, all the wheels must be locked. To lock the wheels, press the
lever on the wheels down. To unlock the wheels, lift the lever up.
The WON COSJET ATR S laser system weighs more than 60 kg and may cause injury if proper
care is not used when it is moved. The system is well balanced and is designed to be moved, but
it should always be moved carefully.
