Crystal oscillators are loosely divided because of the frequency they perform at and whether they are basic oscillators—get the job done 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 dependant on https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
