我们提出了一个分析模型的温度分布，热透镜和热变形的柱面镜反射一个大类的光学读出光束在涂层中的弱吸收率。结果表明，非传统的光束几何形状可以减少在基板和表面的热变形的数量级的热透镜。
We present an analytical model of temperature distribution, of thermal lensing and thermal distortion for a cylindrical mirror reflecting a large class of optical readout beams with a weak absorption rate in the coating. It is shown that nontraditional beam geometries could reduce the thermal lensing in the substrate and the thermal distortion of the surface by orders of magnitude.
