offset lock #9
Description
might be interesting to play with offset locks in the wavemeter.
lock one laser to a cavity as a frequency reference, lock another to the wavemeter (or just use a HeNe)
measure both frequencies on each wavemeter lock iteration
adjust the wavemeter lock set-point based on the measured detuning of the laser locked to the cavity
probably not necessary for new wavemeters, which have a HeNe inside for calibration...
