Laser Troubleshooting
Problem
The laser will not start.
Probable Cause
On water-cooled lasers, bubbles may have developed in the cooling system. This will prevent water from
traveling to the laser head and result in a nonfunctional laser.
Solution
► Procedure
1. Tilt the power supply of the laser 30 degrees right or left.
2. Allow the power supply to remain in that position until the bubbles clear.
3. Try to start the laser again.
Spectrometer Troubleshooting
