摘　　要：报道了一种激光二极管(LD)端面泵浦10at%掺杂Yb∶YAG薄片激光晶体(4mm×1mm)、Ⅰ类临界相位匹配LBO、腔内倍频525nm全固态绿光激光器。采用平凹腔结构,在LD泵浦功率为1.43W时,获得了最高功率为22.3mW的525nm的基模连续激光输出,光-光转换效率为1.5%,光斑椭圆度为0.99。腔内倍频激光器的倍频光输出功率受腔内基频光光子数密度等的影响,最后也对此作了讨论。A laser diode end-pumped 10at% doped Yb：YAG microehip crystal, type-Ⅰ critical phase-matched LBO crystal, intracavity frequency doubled 525nm solid-stated green laser is reported in the paper. Using one piano-concave resonator, with the pump power of 1.43W, 22.3roW TEM00 continuous wave laser at 525um is obtained. The optical conversion efficiency is 1.5%, and the ellipticity of the output beam is 0.99. The output power of intracavity frequency doubled laser is influenced by intracavity photons density of fundamental wave and some other physics quantity, and it also is discussed at last.
