Maintenance
- Page 45 -
The Tempest Nd:YAG laser is a high power laser system and it is
important to keep the laser clean and well maintained. This section
describes several procedures that should be performed on a regular basis
to ensure that the laser system works properly for many years.
It is recommended to inspect the optics in the laser once per month for
burn marks, dust or scratches.
The most common reason for decreased performance in a high power
laser system is dirty optics.
If a noticeable drop in laser energy has occurred, it may be necessary to
flush the cooling system to remove any contaminants. Carbon dioxide
from the air and metal ions will naturally collect in the cooling water
over time. Running the pump allows the deionizing filter to purify the
water
Circulate the cooling water by running the laser power supply and
pump at least 30 minutes each week. This is essential to prevent the
build-up of contaminants in the system, which will be deposited on
the flash lamp and laser rod resulting in decreased output energy. If
you cannot run the laser at least 30 minutes each week, you must
completely drain the cooling system and blow clean, dry compressed
air or nitrogen through the lines.
WARNING!!! Never add tap water to the cooling system. Only
deionized or distilled water may be used.
The deionization cartridge must be replaced approximately once every
two years. The following procedure can be used to replace the
deionization cartridge.
1) Turn the flashlamp voltage knob fully counterclockwise to the
minimum position.
2) Disconnect the lower WATER RETURN hose from the back of the
power supply and hold it over a drain container.
3) Depress the START/STDBY button on the control panel to start the
pump. The pump will force the cooling water from the hose into the
drain container. Repeatedly press the START/STDBY button down
