Standard Operating Procedure for Continuum Surelite Laser Last updated on April 5, 2018

PPE required  Laser goggles

Turning on the laser:

1. The toggle switch labeled AC Power should be in the on position. If it is not, turn it on. The Laser On light should turn on in about 6 seconds. 2. Turn the key switch to the on position (counter-clockwise). Wait a few seconds for the laser to finish diagnostics. 3. Press the Select button to scroll through the settings and verify the correct values. These are: a. Rep Rate: 10 Hz (displays as F10; DO NOT CHANGE) b. Q-switch delay: approximately 365 (low power) c. Pulse Division: P01 (laser output with every flashlamp discharge) d. Pump Voltage: 1.51 kV (DO NOT CHANGE) e. Serial Mode: SoF (serial port off; DO NOT CHANGE) f. External Mode: EoF (external mode off; DO NOT CHANGE) 4. Leave the select in Q-switch mode as you will change this number often. 5. Press the Start/Stop button. The LED should come on. The laser head is now flashing at 10 Hz. Let it warm up for ~20 minutes so that the YAG head thermally stabilizes. 6. Put on your laser safety goggles (should block 1064 nm light). 7. Slide the exit port shutter on the front of the laser to Open. 8. Press the Shutter button. The LED should come on. Laser radiation is now leaving the laser. You should hear a “click” sound as the shutter opens. 9. To change the power changes the Q-switch delay as follows:

Delay settings Note 360-375 Low power; good for laser alignment 300-350 Medium power 200-300 Higher power Around 185-190 Maximal power

Turning off the laser:

1. Press the Start/Stop button. The LED should go off and the LED on the Shutter button should also go off. The flashlamps should stop flashing. 2. Slide the exit port shutter on the front of the laser to Closed. 3. Turn the key clockwise to the Standby position. The Laser On light will turn off. After 1 second, a beep will sound and the system will power off. The LED display should read oFF. 4. Leave the AC Power toggle switch in the on position.
