Optimum Optical Crystal Size When ordering a NLO optical crystal, nonlinear optical crystal orientationand size have to be known. The orientation is solely determined by the nonlinear optical process. The nonlinear optical crystal size is divided into three dimensions noted as WxHXLmm3. The careful design of crystal size is important because the conversion effciency has direct […]
