XeCl激光泵浦S_2分子获得紫外激光振荡

A Near-Ultraviolet Laser with XeCl Laser Pumped S_2

本文报道利用ＸｅＣｌ准分子激光（３０８．１ｎｍ）横向泵浦硫双原子分子激光器，在近紫外谱区（３３０．９～３９０．０ｎｍ）的六条谱带上获得激光振荡．计算并测量了Ｓ２分子的吸收系数及小信号增益系数，从而确定了最佳泵浦波长．

The laser oscillation on six spectrum bands of S2 molecules in near-ultraviolet(330. 9～390. 0 nm) was obtained. The pumping XeCl excimer laser (308. 1 nm) actedon sulfur vapor cell transversely. The absorption coefficients and small signal gaincoefficients of S2 molecules were calculated and measured. The optimum wavelength forpumping S2 was discussed.
