All-Solid-State CW 12.9 W TEM00 Mode Green Laser
摘要
选择低掺杂浓度的Nd∶YVO4/YVO4复合晶体, 设计了V字型热不灵敏折叠式谐振腔, 利用I类非临界相位匹配LBO非线性晶体倍频, 当抽运功率为30 W时, 获得连续单横模绿光最高输出功率12.9 W, 光-光转换效率为43%。当输出功率为11.7 W时, 测量其长期功率稳定性优于±0.83%(自由运转3 h),光束质量传输因子M2小于1.5。
Abstract
A CW laser consisting of a low-doped Nd∶YVO4/YVO4 composite crystal and an I-type phase-matching LBO frequency-doubler with a three-mirror V-fold thermal unsensibility resonator is designed and constructed. A maximal output power of 12.9 W at 532 nm wavelength is obtained under a pump power of 30 W with an optical-optical conversion efficiency of 43%. The long term intensity fluctuation over 3 hours free-operation and the beam transfer factor M2 measured at the output power of 11.7 W were less than ±0.83% and 1.5, respectively.
