| 摘 要： | 基于传输矩阵理论,针对端面抽运的z型折叠腔Nd∶YVO4固体激光器的谐振腔设计进行了数值模拟,详细分析了腔内各参量对谐振腔稳定性的影响.由模拟结果推断,z型腔激光器具有两个稳区,并且稳区的范围可通过谐振腔各分臂的臂长来调节.利用相同的光学元件在不同的稳区范围设计了两种热稳腔,指出了长短腔型各自的利弊.实验考察了输出功率随腔长改变的变化情况,在不同腔长下的不同稳区分别获得了稳定的1 342 nm激光输出,谐振腔稳区范围的变化规律与理论计算基本符合. |

| Abstract: | According to the transmission matrix theory,the resonator design of end-pumped 4-mirror folded cavity Nd∶YVO4 solid-state laser is numerically simulated,the relations between the parameters of cavity and stability is analyzed.A conclusion is that there are two stable regions of 4-mirror folded cavity,whose range can be regulated by the length of each arms of cavity.Using the same optical components,two kinds of thermal stable cavity are designed in two different stable regions.From the experiment,the relations between output power and the length of cavity are observed,1 342 nm laser is obtained by different resonators in different stable regions, and the results are in agreement with the theoretical analyses. |
| Keywords: | Thermal focal length End-pumped 4-mirror folded cavity |
