摘要
采用热助推泵浦技术,实现了885 nm LD热助推泵浦的板条Nd∶YAG脉冲激光器运转。从粒子跃迁机理上对热助推泵浦方式做了理论分析,并通过实验验证了885 nm热助推泵浦相对于802 nm泵浦的优势。885 nm热助推泵浦的光光效率比802 nm泵浦方式提高了26%,废热产生则减少了约23%,结果表明热助推泵浦方案在热性能相对传统泵浦有明显的优势。
Thermally boosted pumping scheme is adopted, pulse laser emission successfully is demonstrated in a slab Nd： YAG crystal under LD thermally boosted pumping at 885 nm. Theoretical analysis of thermally boosted pumping has been done according to particle transition, experimental comparing between 885 nm thermally boosted pumping and 802 nm traditional pumping has been done. The optical-to-optical conversion efficiency has increased 26% than traditional pumping,and heat generated is about 23% less than traditional pumping. Results reveals that thermally boosted pumping scheme has more advantage in thermal characteristics than traditional pumping scheme.
