Laser modeling and simulation can be used to reliably determine the the best possible crystal Proportions, doping density And maybe values of added parameters.人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。The host crystal is
A vital position to emphasise is that it's not merely more difficult to estimate band constructions of 2D photonic crystals, but additionally harder to uncover models which exhibit total band gaps inside the feeling that inside a particular range of optical frequencies there is not any course in the slightest degree in which mild can propagate with
