During grad school, Steve spent a bunch of time monkeying around with AODs (acousto-optic deflectors, see: wikipedia:AOM) during the construction of otpical tweezers. He spent sometimes months over-analyzing some of the problems encountered and accumulated a lot of data that hasn't been published. He'd like to put that data on OWW to save time for others who may encounter those problems.

Wiggles caused by AOD on the quadrant photodiode

Amazing diffraction patterns caused by acousto-optic effects

Schaefer-Bergmann diffraction? Possible the root cause of the AOD cross-hatching and detector wiggles?

Loops
