| 摘 要： | 钠导星激光研制需激光线宽在一定范围内可调节。开展了F-P标准具压窄线宽数值模拟，设计一台高光束质量基横模线偏振激光输出全固态1064 nm激光器作为实验装置，结合激光器输出光谱特性进行计算。根据计算结果采用不同规格的单标准具、组合双标准具实现了激光线宽在0.75 ~2.83 GHz范围内的离散调节控制。在标准具未控温情况下，不同线宽时激光中心波长保持1064.58 nm，30 min内波长漂移量小于3 pm。

| Abstract: | Sodium guide-star laser research needs laser linewidth tunable within a range. The numerical simulation of linewidth compressing by Fabry-Perot etalon has been done, using an all-solid-state 1064 nm laser with high beam quality and linear polarization output as the experiment device, the spectrum of laser is test and put into the calculation. Linewidth discrete tuning in the range of 0.75-2.83 GHz is achieved by inserting different single etalons and combinations of etalons selected by the simulation results in the cavity. Without temperature control of etalon, the central wavelength of laser is fixed to 1 064.58 nm in linewidth tuning, and the wavelength excursion is less than 3 pm in 30 minutes. |
