摘要：

A　light-pumped　high　efficient　Nd:YAG　KTP　frequency-doubled　green　laser　is　demonstrated.　Utilizing　a　L-shape　folded　resonator　and　a　KTP　crystal　for　intracatity　frequency　doubled,　a　maximum　average　output　power　at　532　nm　of　63W　is　obtained　at　10　kHz　repeated　rate　when　the　pump　current　is　set　at　16　A.　The　beam　quality　is　comparatively　feasible,　and　the　fundamental　frequency　ingredient　is　less　than　1%.Additionally,　a　light-to-light　conversion　efficiency　of　63.8%　is　acquired　when　the　repetition　rate　is　set　at　8　kHz.　During　the　experiments,　the　stability　of　the　green　laser　output　power　is　analyzed　theoretically.
