Recently , with the development of good quality nonlinear frequency - conversion crystals and solid - state laser used as pump source , research activities in this area is heating up 近年來,隨著高質(zhì)量非線性頻率變換晶體和固體激光器抽運(yùn)源的快速發(fā)展,這一領(lǐng)域的研究異?;钴S。
Theoretically , on the bases of the physical and chemical characters of nonlinear frequency - conversion crystal ktp , the parameters such as walk - off angel , acceptance angle and effective nonlinear coefficients are calculated , analyzed and discussed , together with elaborate analysis to phase - matching process for type ii ktp opo phase - matching 在晶體的光學(xué)性能方面,根據(jù)ktp的物理和化學(xué)性能,對它的有效非線性系數(shù)、走離角和接受角等參數(shù)進(jìn)行了計(jì)算、分析和討論。對ii類相位匹配的ktp晶體在參量振蕩過程中的相位匹配進(jìn)行了詳細(xì)的分析和計(jì)算。
