[Laser] Modulation by quartz xtal

[Chuck Houghton]

James I forgot what the crystal is called but its a crystal element driven by about 12 to 1 watt of rf in the 70 to  140 or so mhz range impinging modulation FM on it. When the laser beam is passed through this device it imparts fm modulation on the laser beam. Lithium Niaobate. and I am not sure of the spelling is the crystal I was talking about. There is a way to impart modulation on a crystal in your setup and it requires phase additive circuitry to make it work not familiar with its setup. Chuck WB6IGP
