Crystal oscillators are loosely divided via the frequency they work at and whether they are fundamental oscillators—function for the frequency marked over the can or at even multiples of that (overtone oscillators). We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output based on the orthogonal thermal payment https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
