Crystal oscillators are loosely divided because of the frequency they do the job at and whether they are fundamental oscillators—operate in the frequency marked to the can or at even multiples of that (overtone oscillators). We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output determined by the https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
