摘要
采用自准直法测得掺MgO 0.05 mol的LiNbO3(LN)晶体在室温下的主折射率,拟合出LN晶体在室温下的1类相位匹配公式,计算得到1079.5 nm和1341.4 nm等波长的临界相位匹配条件。计算结果与实验结果相差小于1°。
Abstract
Refractive indices of LiNbO3:MgO(5mol%) at room temperature have been measured by the auto-collimation method. Based on these refractive indices, we obtain the relationship between type I phase matching angle and the wavelength. Then use it to calculate the phase matching conditions at 1079.5 nm and 1341.4 nm. The reliability of the results has been verified by 1079.5 nm and 1341.4 nm Nd:YAP pulse lasers. The errors between calculated results and experimental results are less than 1°.
