Each individual laser must reach the 20% line by its second shot. If any of the laser cavities do
not, the alignment of that particular cavity may need peaking. Also, check the mode burns at
this point. Note that even if the burn may look good, the cavity may need peaking.
NOTE: It is permitted for the first shot of each cavity to fall below 20% line on the
graph.
c. Repeat step b above with the laser set at each of the following operating points:
5 Hz (or maximum available), 0.5J
5 Hz, 3.5J
40 Hz, 2J (for 80W systems) or 30 Hz, 2.7J (80/100 systems)
2. Inspect debris shield and clean/replace as required.
3.7 OPERATIONAL AND SAFETY CHECKOUT
CAUTION: The operational tests include firing the system and attempts to fire the system with one disabling
condition. Select a low power setting and direct the test fiber output into a calibrated power meter.
Attach a test fiber and verify the remote interlock plug and footswitch is connected, then check the system
operation as follows:
1. Check the circuit breaker.
a. Connect the system to the AC power source and turn OFF the circuit breaker. Verify there is no AC
voltage present at.
b. Turn ON the circuit breaker and verify there is Ac voltage present at
2. Check the keyswitch.
a. Rotate the keyswitch to the II (start) position; hold for one second and release the key. Upon release,
the spring-loaded key rotates to the I (on) position. Verify the system turns on proceeds with the self-
test routine and the key cannot be removed from the keyswitch.
b. Rotate the key to the (off) position and verify the system turns off.
