摘要
Nd：YAG最强的跃迁发生在1064nm，其荧光线宽大多为4～6cm，故Nd：YAG激光器通常将产生1064nm多纵模输出。为获得1319nm输出，对主要元件的特殊膜层进行了设计，从而抑制了其他波长在腔内的振荡。讨论了标准具的波长调谐和纵模选择特性，通过调整标准具的倾角实现了对波长的调谐，通过两块厚度不同的标准具组合实现了3个连续纵模的选择，这样使得1319nm激光器能获得3个连续纵模的输出。
The strongest transition of the Nd： YAG occurs at 1 064 nm, which exhibits a fluorescence linewidth of 4-6 cm^-1 , the Nd： YAG laser shows multiple longitudinal-mode operation at 1 064 nm usually. In order to obtain the laser emission at 1 319 nm, key mirror coatings are designed, which suppress the unwanted oscillations in the cavity. The properties of wavelength tuning and longitudinal-mode-selecting of Fabry-Perot etalon are discussed. The output wavelength is tuned by adjusting the tilt angle of etalon and three adjacent longitudinal modes are obtained with two etalons. The 1 319 nm laser＇s requirements could be satisfied.
