Mp025 Aom Settings
Light from MP023
Light is picked off from the K repump line in MP023, after it has been locked to the 39K F=2 -> 2P3/2 (unresolved), then shifted an additional ~-308MHz by AOM1 and AOM2:
| AOM1 | 1x(-116MHz) |
|---|---|
| AOM2 | 2x(-96MHz) |
| Total | -308MHz |
note: values on MP023 Laser Settings may be a little different.

| AOM Name | AOM Frequency (MHz) | Order | Number Passes | Actual Optical Freq Shift (MHz) |
|---|---|---|---|---|
| AOM1 (sat. spec.) | 65 | +1 | 2 | 65 |
| AOM2 (freq. control) | 86 (MOT) / 70 (imaging) | -1 | 2 | -172 / -140 |
| AOM3 (amp. control) | 65 | +1 | 1 | 80 |
