The two oscillator circuits down below are ideal for working with crystal oscillators in series or parallel method: We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output determined by the orthogonal thermal payment architecture. The asymmetry of thermo-optical consequences in the anisotropic… 中原子或分子的排列具有三维空间的周期性，隔一定的距离重复出现，这种周期性... https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
