Crystal oscillators are loosely divided from the frequency they operate at and whether or not they are basic oscillators—get the job done at the frequency marked about the can or at even multiples of that (overtone oscillators). We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output according https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
