Abstract

A crucial factor in achieving high efficiency during second-harmonic generation is maintaining a constant temperature along the beam propagation in the nonlinear crystal, despite a significant non-homogeneous heat input through absorption. In this context, we present a theoretical approach to determine the necessary longitudinal oven temperature profile applied to the crystal’s shell surface to ensure a constant temperature at the center along the propagation axis. The approach is validated through simulations for an exemplary case, followed by a discussion of the results.

二次谐波发电中相位匹配的烘箱温度分布：一种理论方法

在二次谐波产生过程中，实现高效率的一个关键因素是在非线性晶体中保持光束传播的恒定温度，尽管通过吸收输入的热量是非均匀的。在这种情况下，我们提出了一种理论方法来确定应用于晶体壳表面的必要的纵向烤箱温度分布，以确保沿传播轴的中心温度恒定。通过一个实例的仿真验证了该方法的有效性，并对结果进行了讨论。
