285 nm-Laser (S-MOT)

• Laser Enable: push “on”
• Output Power: change “Power Setpoint”
  • 0.500 W for Iode spectroscopy fiber coupling
  • 2 - 2.500 W for 285 nm-SHG-Lock
• Seedpower: ~ 20 mW

1. S-MOT-Laser connected
2. start “DigiLock - SN 01265 - S-MOT-Laser”: double click of S-MOT-Laser
   1. push “Scan on”
   2. push “AutoLock”
   3. change the “Offset Value” to 0 V
   4. change the “Setpoint” (under “AutoLock”) of max slop of the middle peak
   5. Push “PID: Lock to Slop”

The system was build by Jan Friebe and is described in his diplomathesis.
