19 Calibrate HVPS
19.1 Power on laser
19.2 Type < cv> from the “C:\” prompt (CV mode).
19.3 Press “Utility” button
19.4 Press “Calibration” button
19.5 Press “Calibrate HVPS” button
19.6 Follow instructions displayed on the utility screen.
19.7 When cal is completed press the “EXIT“ button to dump the high voltage.
19.8 Return S1 to normal operation, Set S1 position 1- 8 OFF on the ETX Board (#710-0138-000).
20 Align ND: YAG Maximum Reflector
20.1
Remove the beam combiner block.
20.2
Power up laser
20.3
Type < cv> from the “C:\” prompt (CV mode).
20.4
Position the Ophir F250A-HL detector head between 14” to 16 ” from YAG resonator
chamber. Align the F250A-HL detector disk with the YAG resonator output.
Set: NOVA II Power Meter
Menu = Power(Watts)
Range = Auto
Average = 1-second
Laser wavelength = NIR or 1064.
20.5
Set: Cynergy Laser
Voltage = 450 V (set voltage to obtain ~ 3watts)
Pulse width = 5 ms
Rep rate = 1 Hz
20.6
Center a piece of ‘ZAP-IT’ laser alignment paper in front of the F250A-HL detector disk.
20.7
Fire laser a single shot into the ‘ZAP-IT’ paper.
20.8
Verify the burn is centered on the F250A-HL detector disk. Re-position the energy
detector if necessary.
20.9
Using the optics alignment tool, adjust the 3 screws on the max. reflector for a circular
burn pattern with sharp edges.
20.10
Fire a single shot on an unexposed area of the “ZAP-IT” paper after each adjustment,
until proper exposure is obtained.
20.11
When correctly adjusted the burn should be circular and uniform with no internal
structure, such as rings or spots on the “ZAP -IT” paper.
20.12
Once satisfied with the burn pattern, lock the mirror adjustment crews in position.
20.13
Fire laser one more time onto “ZAP-IT” paper to verify that tightening the mirrors did not
affect the burn pattern.
