INITIAL START-UP

1
Press the UC-2000’s Lase On/Off button. The Lase indicator on the UC-2000 should illuminate.
2
Use the PWM Adj Knob on the UC-2000 Controller to slowly increase power. The LASE LED
turns red when PWM Command signal pulses are long enough to produce laser output (typically
7–10
μ
s at 5 kHz). The spot where the beam hits the beam block increases in brightness to
indicate increased power output.
3
Press the UC-2000’s Lase On/Off button to stop lasing. Lase indicators on the UC-2000 and the
laser should both turn off.
4
If you are connected to the i401’s Ethernet port, access the i401 web page to verify operating
conditions and functionality (refer back to Figure 1-13). See the Getting Started or Technical
Reference sections for details on accessing the I401 web page.
While purge gas is flowing, check the Relative Humidity value. The measured value should drop
to 0% (± 10%) within 10–15 minutes. If the relative humidity never drops below approximately 10%,
then increase the flow rate slightly.
5
Remove DC power from the laser.
6
Shut off the chiller or otherwise stop coolant flow through the laser.
7
Shut off gas purge flow to the laser. In dirty or dusty environments, however, it may be necessary
to purge the laser continuously to prevent contamination of internal optics.
If your i401 laser fails to lase, refer to Troubleshooting in the Maintenance/Troubleshooting section for
troubleshooting information.
Without a UC-2000 Controller
If you have chosen not to use a UC-2000 to control the laser, follow the procedure below to verify the
laser’s functionality. Although a tickle signal is not required, you will need to provide PWM Command
signals to I401’s User I/O connector. Refer to User I/O connections in the Technical Reference section for
connector pinouts and refer to Controlling laser power in the Technical Reference section for Command
signal descriptions.
Danger: Serious Personal Injury
Because of phase differences, external tickle pulses may combine with the internally generated
tickle signal causing the LASE LED to flicker during the transition from tickle to lasing. Laser
output may occur if the LASE LED flickers.
Caution: Possible Equipment Damage
Do not flow coolant through the laser when the laser is shutdown. This causes condensation to form
inside the laser which may result in catastrophic damage to internal optics and electronic circuits.
