摘　　要：报道了一台800Hz,6.2W外腔和频的589nm黄光激光器。基频激光器均采用双棒串接平平对称腔,增益介质为Nd:YAG晶体,采用声光调Q方式分别获得11.1W的1 064nm激光和12.6W的1 319nm激光。和频晶体采用三硼酸锂(LBO),尺寸为4mm×4mm×30mm,采用Ⅰ类非临界相位匹配。将两束激光通过分光镜合束,聚集后注入LBO晶体,获得589nm黄光最大输出功率为6.2W,脉宽为50ns,和频效率26.2%。x方向和y方向的光束质量平方因子分别为3.20和3.61。A 6.2 W 589 nm yellow laser at a repetition rate of 800 Hz was reported.Double rod and symmetry plane-plane cavity was adopted.The gain medium was Nd：YAG,11.1 W 1 064 nm and 12.6 W 1 319 nm was obtained by acousto-optic（AO） Q-switched.The sum-frequency medium was a 4 mm×4 mm×30 mm lithium triborate（LBO） crystal with type Ⅰ critical phase match.Two beams were combinated with beam splitter and focused into the LBO crystal.A maximum power 6.2 W of the 589 nm laser was obtained,laser pulse width was 50 ns.The sum-frequency efficiency was 26.2%.The beam quality factor was 3.20 and 3.61 respectively in parallel and perpendicular direction.
