Crystal oscillators are loosely divided via the frequency they operate at and whether they are essential oscillators—do the job on the frequency marked around the can or at even multiples of that (overtone oscillators). We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output based upon the orthogonal https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
