摘　　要：基于ＭｇＯＬｉＮｂＯ３（ＭｇＬＮ）晶体的Ｓｅｌｍｅｉｅｒ方程，计算了１０７９．５ｎｍ和１３４１．４ｎｍ激光在该晶体中和频的相位匹配条件和容承角，计算结果用１０７９．５ｎｍ和１３４１．４ｎｍ双波长ＮｄＹＡ－ｌＯ３（ＮｄＹＡＰ）连续激光在ＭｇＯＬｉＮｂＯ３晶体中的和频进行了实验论证，两者相当符合，并得到了连续的５９８．１ｎｍ橙色相干辐射。讨论了１０６４ｎｍ和１３１８ｎｍ双波长ＮｄＹＡＧ激光在ＭｇＯＬｉＮ－ｂＯ３晶体中实现双波长和频获得５８８．７ｎｍ橙色相干辐射的可能性。Based on Sellmeier equations for MgO∶LiNbO 3(Mg∶LN) crystal, the phase matched condition and acceptance angle for sum frequency generation of a radiation at wavelengths of 1079.5 nm and 1341.4 nm have been calculated. The calculated results were verified by the sum frequency generation in MgO∶LiNbO 3 crystal with a 1079.5 nm and 1341.4 nm dual wavelength Nd∶YAlO 3 (Nd∶YAP) CW laser. A CW coherent orange radiation at wavelength of 598.1 nm has been achieved. The possibility to obtain the 588.7 nm coherent orange radiation using a 1064 nm and 1318 nm dual wavelength Nd∶YAG laser in MgO∶LiNbO 3 crystal was also discussed.
