31 Calibrate YAG Cal Port
31.1
Verify the beam combiner block is installed onto the rail.
31.2 Install the SMA/focus lens assembly onto the beam combiner block.
31.3
Screw the beam combiner block to the rail.
31.4 Install fiber cable into SMA connector
31.5 Install a 7-mm hand piece onto fiber cable.
31.6 Power up laser
31.7
Type < cv > from the “C:\” prompt (CV mode).
Set Laser Set NOVA II Meter
WL = YAG Laser Type = NIR or 1064
Voltage = 700 Average = 3sec
Pulse Width = 5ms Range = AUTO
RepRate =1Hz
Measurement = power
31.8 Position the 7mm handpiece so it is facing into the OPHIR detector head.
31.9 Press lower case ‘ e ’ to allow Ext shutter to open when laser is fired.
31.10 Adjust the laser voltage and re-fire the laser and until the NOVA II power meter reads 35watts
+/- .5W. Make note of the power reading to be used in a later step.
31.11
Record the laser voltage setting on Data Sheet #991-4909-000.
31.12 Move the 7mm handpiece into the Cal Port.
31.13 Set YAG Cal Port Gain = 10 .
31.14 Fire laser six shots.
31.15 Verify YAG Cal voltage measure between .5 and 1.25 volts .
31.16 If YAG “cal” voltage is to low, decrease the gain # (press lower case “ c ”).
31.17 If YAG “cal” voltage is to high, increase the gain # (press upper case “ C ”).
31.18 Note: valid gain values are 1 -15.
31.19 Re- Fire the laser 6 shots and read the YAG “cal” voltage from CV screen.
31.20 Press upper case ‘ U’ and enter the actual Ophir meter reading from step 31.10
31.21 Fire laser again into Calport and verify YAG Cal Port energy measures
35 Watts +/- .5 Watt.
31.22
Record YAG 5ms “cal” voltage value on Data Sheet #991-4909-000 .
31.23
Record YAG 5ms “cal” gain value on Data Sheet #991-4909-000 .
31.24
Record YAG 5ms “cal” j/v value on Data Sheet #991-4909-000 .
