A flash lamp pumped Cr,Er:YSGG laser utilizing a langasite (LGS) crystal as an electro-optic Q-switch is proposed and demonstrated. It is proved that a LGS crystal with relatively high damage threshold can be used as the electro-optic Q-switch at 2.79 μm, and 216 mJ pulse energy with 14.36 ns pulse width is achieved. Its corresponding peak power of pulse can reach 15 MW, to our knowledge the best result at a 2.79 μm wavelength.
提出并演示了一种利用 langasite (LGS) 晶体作为电光 Q 开关的闪光灯泵浦 Cr,Er:YSGG 激光。实验证明，相对较高的损伤阈值的 LGS 晶体可用作 2.79μm 的电光 Q 开关，获得了 216mJ 脉冲能量和 14.36ns 脉冲宽度。其相应的脉冲峰值功率可达 15MW，据我们所知，这是在 2.79μm 波长下的最佳结果。
