The 2 oscillator circuits beneath are suitable for making use of crystal oscillators in series or parallel mode: We present a Nd:GdVO4 bulk crystal oscillator with >70 WTEM00 laser output based on the orthogonal thermal compensation architecture. The asymmetry of thermo-optical effects within 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，这种周期性规律... https://www.hxcrystals.com/seokeywords/bulk-crystal-oscillator.html
