| 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. |
