Crystal oscillators are loosely divided through the frequency they function at and whether or not they are fundamental oscillators—function with 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 https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
