Start-up and pulsed operation
Initial start-up with UC-2000
Controller
Before your Pulstar OEM p100 laser is put into service for the first time, follow this procedure to verify the
laser system is operating at optimum performance. For this procedure, use the UC-2000 as a stand-alone
controller; do not attempt to control the laser or UC-2000 externally.
Important Note: Except for bench testing, we do not recommend using a UC-2000 Controller with
the Pulstar OEM p100 laser. The automatically-generated tickle signal from the UC-
2000 may interfere with the laser’s pulsing performance.
Note: Before performing the initial start-up sequence, you must first connect the
Quick Start Plug
or you
must provide the required Remote Interlock and Shutter Open Request signals to the
User I/O
connector. See
User I/O
connections in the Technical Reference chapter for interface details and
signal descriptions.
Starting auxiliary equipment
1 Ensure that all personnel in the area are wearing protective eyewear.
2 Remove the red self-adhesive aperture seal covering the laser aperture.
3 Place a power meter, or appropriate beam block, 61 cm (24 in) from the laser aperture to prevent the
beam from traveling beyond the work area.
4 Connect the Quick Start Plug to the User I/O connector on the rear of the laser and then connect
the UC-2000 (or alternate PWM signal source) to the BNC connector on the Quick Start Plug .
Caution
possible
equipment
damage
Inlet cooling water temperature must always be maintained above the
dew point to prevent condensation and water damage to your Pulstar
laser.
5 Turn on the chiller and set a temperature setpoint between 18 °C–22 °C. Verify that the chiller is
delivering a flow rate of 5.7–7.6 lpm (1.5–2.0 GPM) at less than 414 kPa (60 PSI) of pressure.
Examine all cooling connections carefully and ensure that they do not leak.
Caution
possible
equipment
damage
Do not exceed a gas purge pressure of 34.5 kPa (5 PSI). Excessive
pressure may damage the purge assembly or other internal laser com-
ponents.
Do not use argon as a purge gas. Use only nitrogen or clean, dry air as
described in Table 1-3,
Purge gas specifications .
