| 摘 要： | 一、引言 铜蒸气泵浦染料可调谐激光器具有重复率高、输出功率高等优点,是应用激光光谱中的重要激光器件。器件结构见图1。用Littrow光栅和平面镜组成了谐振腔。如图1的染料激光器的前腔板一般都采用平板玻璃(R=8％),其优点是装调方便,但考虑到染料槽的宽度只有0.3mm,光束的衍射角大(约2.5mard),因此谐振腔的衍射损耗大。在某些实际应用中,M_1与染料槽间往往还要留出一段距离以便插入光学元件,衍射损耗则将加大。为了提高器件的效率,我们采用凹面反射镜代替平板。

Output power of dye laser pumped by Cu vapor laser with different oscillator structures |
| |
| Abstract: | By meana of experiment and simple theory; we investigated the output’ power of the tunable dye laser pumped by a Cu vapor laser with planar and concave mirrors used as the front mirror of the dye laser respectively. The experimental result shovs that for the same oscillator length there is a higher output pbwer for the concave one than that for the planar one, which agrees with our theory. |
