DIODE LASER ARRAYS SIDE-PUMPED DOUBLE-SLAB LASER
【摘要】 叙述了二极管面阵侧泵浦双板条耦合单模模Q开关激光器的研制。泵浦源为二极管面阵激光器,使用梯形波导板耦合系统,耦合效率达90%,谐振腔为凸凹腔,全反射镜、的曲率半径为3.0m的四面镜,输出镜为曲率半径3.0m的可变反射率超高斯镜。激光器在100Hz重复频率下,输出单脉冲能量18.23mJ,脉宽为15.25us,光束质量M2<1.5具有平顶分布的超高斯光束。
【Abstract】 A diode side-pumped Q-switched Nd:YAG double-slab oscillator designed for high powersolid state laser has been demonstrated. Diode laser power was transferred by a trapezoidal waveguide plateinto the slabs and the optical coupler efficiency was 90%. The oscillator was a convex-concave resonator.High-reflection mirror of curvature radius was 3.0m. A VRM of super-gaussian was used for output couplerswith curvature radius of 3. 0m. The output is of single pulse energy 18. 23mJ, pulse width 15. 25us and100Hi repetition rates and beam quality factor. The output beam was a flat topped super-gaussian beam.
