高功率TEA CO2激光器的双波长免调切换结构
High power TEA CO2 laser with two wavelength free shift output structure
摘要
Abstract
To realize 10.6/9.3 μm two-wavelength high energy laser switching output on one laser,a coating on output mirror was taken to obtain a 9.3 μm singlet output whose pulse energy was roughly equal to 10.6 μm. A two-wavelength window switching device with free shift out strucutres was designed. The statics analysis, thermal-stress analysis and the thermal-stress coupling analysis were used in the switching shift flat to get the displacement deformation by MSC. Patran/Nastran software,then the least square method was taken to get the output mirror deflection angle around the axis by Matlab software. The results indicate that the maximum stress of structure is 101 MPa, the maximum deformation of mirror is 6.95 μm,and the mirror deflection angles around the axis are 0.07″,2.92″ and 0.009″ , respectively. A emission experiment for the physical device was performed,which shows that the directional relative error of two wavelength shift emission is 8.7″. The results mean that the structure can satisfy the requirements of the free shift output of two wavelength lasers for capabilities and parameters.关键词
