After reading about how the BVA oscillators avoid the problems of "on
crystal" electrodes I was wondering if anyone has tried to optically
excite a quartz crystal in an oscillator?
(Use a modulated laser to drive the bare crystal, and a photodetector
setup to detect and provide feedback?)
Seems like it might work. Any comments?
I only wonder if you can get sufficient drive-level that way. I haven't
heard about a way to drive quartz optically even if I can consider a few
different mechanisms. You have any papers on that?
Optically sensing the vibration I consider trivial.
Cheers,
Magnus
