研究了 L D泵浦的单频种籽激光器。以 Nd:YAG和 Nd:YL F晶体为工作介质 ,采用微片腔的谐振腔形式 ,获得了 1.0 6μm和 1.0 5 3μm的单频激光输出 ,其输出功率分别为 90 m W和 10 m W。采用光纤延迟自零差拍法测量了单频固体激光的线宽 ,其线宽为 30 0 k Hz。
L D pumped single frequency seed laser was studied. Using Nd: YAG and Nd: YL F crystals as the working medium, the single-frequency laser output of 1.06μm and 1.05μm with the output power of 90 mW and 10 mW respectively was obtained. The linewidth of a single-frequency solid-state laser was measured by optical fiber delay zero-beat method with a linewidth of 30 0 k Hz.
