We report for the first time, to our knowledge, the diode-pumped continuous-wave(CW) thin-disk Yb3+-doped Lu2O3(Yb:LO) laser at 1 034 nm and the second-harmonic generation at 517 nm.

With a 6.3% output coupler, the maximum output power is 1.17 W under a pump power of 18.5 W. Moreover, the intracavity second-harmonic generation(SHG) is also achieved with power of 193 mW at 517 nm by using an LiB3O5(LBO) nonlinear crystal. The beam quality factor M2 is about 1.28. The fluctuation of the output power is about 3% in 1 h.展开更多
