LD End-pumped Self-mode-locked Laser's Coupling System

摘要: 为了满足克尔透镜锁模的严格条件,对LD泵浦自锁模激光器的泵浦光路整形系统进行了理论分析和实验验证.在考虑球差的情况下,设计了一套结构简单、耦合效率70%以上的整形系统,得到了满足锁模条件的46.9 μm × 45.1 μm的光斑.

Abstract: Considering the effect of the spherical aberration, a coupling system used in the LD end-pumped KERR-lens mode-locked system has been analyzed in detail. The relationships between the mirrors'parameters and the light spot width has been calculated. At last, a practical and effective coupling system is designed, which is special for the Self-mode-locked system of 46.9 μm × 45.1 μm.
