Laser stepwidth |
|
|
From previous Bi-Beamtimes, we expect the width of the transition to be >50GHz (FWHM). The current step width is 0.002nm which corresponds to 8GHz, so the laser would be in resonance for 6 steps.
We should aim for at least 5 steps in resonance.

line width (sigma) | >20GHz
| |
FWHM | ~50GHz
| |
step width (fundamental) | 0.004nm (4GHz)
| |
step width (doubled) | 0.002nm (8GHz)
