We report a simple theoretical model for the calculation of the dependence of filter quantum efficiency versus laser pump power in an atomic Rb vapor laser-excited optical filter. We present the calculations for a 532.4-nm Rb filter that can be used to detect the practical and important frequency-doubled Nd:YAG laser. The results of these calculations show that the filter's quantum efficiency is relatively insensitive to the laser pump power. The laser powers required to pump the filter range from 3.6 to 226 mW per square centimeter of filter aperture.
我们报告了一个简单的理论模型，用于计算原子铷蒸汽激光激发光学滤波器中滤波器量子效率与激光泵浦功率的依赖关系。我们给出了一个可用于检测实际且重要的倍频Nd:YAG激光的532.4纳米铷滤波器的计算结果。这些计算结果表明，该滤波器的量子效率对激光泵浦功率相对不敏感。泵浦该滤波器所需的激光功率范围为每平方厘米滤波器孔径3.6至226毫瓦。
