We demonstrate that the etalon effects of alkali cells can be used as the output coupler of an alkali laser. Based on a rubidium cell with highly parallelized windows, a 2.7 W rubidium laser with optical efficiency of 20.9% and slope efficiency of 31.8% is obtained by adopting unconventional output couplers. Since it has compact configuration and the inner surface of the rubidium cell is uncoated, this may be used in high power laser systems with long lifetimes.

基于碱池窗口标准具效应的二极管泵浦铷激光器

我们证明碱性电池的标准具效应可用作碱性激光器的输出耦合器。基于具有高度平行化窗口的铷电池，采用非常规输出耦合器获得2.7 W铷激光器，光效率为20.9%，斜率效率为31.8%。由于它具有紧凑的结构并且铷电池的内表面没有涂层，因此可用于长寿命的高功率激光系统。
