掠入射光栅调谐脉冲染料激光器的复合腔研究

Investigation on the Compound Cavity of Pulse Dye Laser Tuned by Using Glancing Incidence Grating

从理论上分析了掠入射光栅调谐复合腔染料激光器的运转特性,得到了复合腔激光线宽变窄与输出能量增加的条件,实验结果与理论一致。

The operating properties of the pulse dye laser with the compound cavity,whichtunes using the glancing incidence grating,is analysed theoretically in this paper.We found theconditions under that the compound cavity can narrow the laser line-width and increase the laserenergy.We experimentally come to that the laser line-width is narrowed by one time and thelaser energy increase by 50% is respectively compared with that of the laser without compoundcavity.
