Crystal oscillators are loosely divided because of the frequency they work at and whether they are basic oscillators—get the job done within 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 according to https://bookmarkfavors.com/story4515413/top-guidelines-of-bulk-crystal-oscillator
