In this paper, we have set up a diode laser pumped rubidium amplifier for higher-order Laguerre-Gauss (LG) modes. We experimentally realized amplification of higher-order LG modes including helical and sinusoidal LG, LG, LG, and LG modes with their high purity held. This novel scheme of generating high-purity higher-order LG beams at high laser power is preferred to the second-generation gravitational wave interferometers. To the best of our knowledge, it is the first time this scheme is formulated.
在本文中，我们搭建了一个用于高阶拉盖尔 - 高斯（LG）模式的二极管激光泵浦铷放大器。我们通过实验实现了包括螺旋形和正弦形LG、LG、LG和LG模式在内的高阶LG模式的放大，且保持了它们的高纯度。这种在高激光功率下产生高纯度高阶LG光束的新方案优于第二代引力波干涉仪。据我们所知。这是首次提出该方案。
