Eye Injury
Visible light laser energy passes through the transparent components of the eye (cornea, lens,
aqueous and vitreous humor), and is focused on the retina. This light can cause an accidental
retinal burn. The degree of injury to the eye will depend upon the power of the beam, how focused
the beam is, and how long the eye is exposed to the beam.
Protective eyewear for the operating room staff and patient should be provided. Laser eyewear
may not be interchangeable between lasers of different wavelength, power or divergence angle.
WARNING: It is required for everyone in the room to wear protective eyewear.
Eyewear has been designed to protect operating room personnel from the 532 nm laser energy.
The eyewear has a minimum optical density (OD) of 6.0 at 532 nm. These types of laser protective
eyewear include:
Nearly clear Physician Laser Glasses. The essentially clear lens material has very high visible
light transmission and minimal color distortion.
Orange Eye Protection Glasses. Although it has good visible light transmission, the orange
color of the plastic lens causes some color distortion.
Burns
Personnel using lasers should be knowledgeable of the fire hazards associated with laser use.
Accidental irradiation of tissue other than the target tissue may result in a burn or vaporization.
Surrounding the target area with moist drapes or saline-soaked sponges will keep it moist and
greatly reduce this hazard.
Flammable or combustible items in the laser environment may include: flammable liquids or
combustible ointments, gases, plastics, paper or gauze materials, adhesive or plastic tapes, and
endotracheal tubes.
Laser appropriate fire extinguishers and water should be available where lasers are utilized. Care
and precision in aiming and applying laser energy is of paramount importance.
WARNING: Never use a clamp to secure the laser fiber to a drape. The use of a
clamp to secure a fiber may cause the fiber to bend at sharp angles
and damage the fiber. To do so can result in an unsafe condition. The
fiber can break and release laser energy causing a burn in the
protective jacket. If undetected, this condition will result in a burn or
ignition of flammable materials.

P/N 0010-0067, Rev A
Reflection of the Beam from Instruments
Care should be taken when aiming the laser beam to prevent reflection of the beam off metallic
surgical instruments. Mirror-finish instruments are especially dangerous as they have highly
reflective surfaces. The laser light reflected from such instruments is intense and potentially very
harmful.
Matte, dull, satin-finished, or ebonized instruments have less glare, and those with curved surfaces
do not reflect light as intensely. While these instruments usually produce a more diffused reflection
that is less harmful, this reflection can still be damaging. Protective eyewear should be worn at all
times to prevent eye damage.
WARNING: When using anodized, black chrome finished, or ebonized instruments
during a surgical procedure, additional care should be taken to prevent
burns. These instruments will become extremely hot when they come
in contact with a laser beam and are not able to quickly dissipate heat.
When any tissue is touched under these conditions, a burn may result.
Ignition of Flammable Materials
The laser can ignite many materials used during a surgical procedure. Use of non-flammable
materials is strongly recommended.
Electrical
Electrical hazards with the laser are the same as with any electrical device. Care should be taken
when plugging the unit into the wall outlet. The area must be free of water and your hands must be
dry.
Always disconnect the laser by grasping the plug and not the power cord. Examine the electrical
cord routinely; if signs of wear are noted, contact AMS to have it repaired or replaced.
Operating Room Environment
This section describes specific safety measures for the operating room to aid in the safe operation
of the Laser System.
Laser Warning Signs
The area where the laser is operated should be clearly labeled. Warning signs that specify the
laser wavelength being used should be posted at all operating room and access-door entrances.
Figure 3-1 is an example of a sign suitable for use with the Laser System.

Remote Door Interlock
Always limit personnel in the operating room to those essential to the procedure. To protect
intruding personnel from exposure to the laser beam, an optional remote door interlock can be
connected from the Laser System to the operating room entrance door. This interlock will
automatically put the laser in STANDBY if the door is opened during a procedure. The laser will
remain in STANDBY until the door is closed and the interlock is reset. Once reset, the operator can
place the system back in READY and reactivate the surgical beam. The laser cannot be placed in
READY unless the interlock is reset.
If the use of the remote door interlock is desired, the biomedical personnel at the user’s facility can
connect it. The user should test the remote interlock prior to each use. Access to the laser unit’s
interlock function is made via a socket located on the back panel of the laser (see Figure 1-2 Rear
View of the Laser System).
Safety Recommendations
The following are general safety recommendations for the operating room and are not specific to
the Laser System:
Keep drapes and towels moist to prevent their ignition and burning.
Use non-flammable prepping solutions.
Prevent combustion of methane gas by packing the rectum during perineal procedures.
Do not use the laser in the presence of flammable anesthetic mixture with air or with oxygen or
nitrous oxide.
WARNING: Do not fire the laser unless the aim beam is clearly visible and
directed at the targeted tissue.
Safety Features of the laser system
Safety Regulations
The United States Code of Federal Regulations, CFR Title 21, Ch. 1, Sections 1040.10, and
1040.11, EN 60825 and EN 60601-2-22 require that lasers have certain safety features. These
regulations and standards further require that labels be affixed to each laser unit identifying the
manufacturer, the class or classes of radiation produced, and the location of the laser aperture(s)
on the unit.

Section 4 Cooling System
Copyright 2009, AMS, Proprietary Information, All Rights Reserved 4-1
P/N 0010-0067, Rev A
GREENLIGHT HPS COOLING SYSTEM
COOLING SYSTEM
Solenoid Valve The solenoid valve is internal to the chiller and it serves to maintain
the proper resistivity of the chiller’s DI water. It will open as needed to allow return
water to flow through a resin, de-ionizing filter cartridge to keep the cooling water’s
resistivity between 0.2 and 0.3 megaohm-cm.
Valve/Flow Switch The Valve/Flow Switch assembly is used to set the diode
stack’s nominal flow rate. The flow rate setting is referenced on a label on the side
of the resonator. The Valve/Flow switch assembly protects the diode from damage
caused when the water flow rate to the diode is below a preset level. When the flow
switch is open, the diode power supply interlock is opened preventing power to the
diode stacks.
Water to Air Heat Exchanger The water to air heat exchanger (HX) is internal to
the chiller. It is actually two separate heat exchangers that move heat from the
laser’s cooling water to refrigerant (R134A) and from the refrigerant to the ambient
air.
INTERNAL WATER COOLING
Description
The cooling system holds roughly 1700ml of water, de-ionized or distilled only. It is
important to maintain approximately 1.5 feet clearance around the laser, especially for
the airflow from the front to the rear of the laser, to avoid overheating. The cooling
system is monitored for temperature and water flow.
Water is added to the cooling system through the fill port and into the reservoir. It then
travels from the reservoir to the water pump. The pump cycles the water to the
resonator to cool the diode, YAG Rod and Q-Switch. The water circulates through the
diode power supply, into the resonator and exits the resonator through the water outlet
fitting. The water then goes through the chiller for cooling and D.I. polishing (as
needed). Air is pulled via a fan through the air-to-water heat exchanger to cool the D.I.
water.
Fill and Drain Ports:
The fill and drain port is used to fill and drain the laser’s internal cooling system.
Fan:
The fan speed is constant and controlled by the chiller.

Section 4 Cooling System

P/N 0010-0067, Rev A
Pump and Motor:
The pump is rated at a maximum flow rate of 2.5 GPM. If the pump is run dry, damage to
the pump will occur. The pump is energized when the key switch is turned to the ON
position.
