High-power and wavelength tunable diode-pumped continuous wave Yb：SSO laser

A wavelength-tunable,efficient,and high-average power single diode-pumped continuons wave(CW) Yb:SSO laser is reported.A maximum output power of 8.8 W at 1 062.6 nm is obtained using the absorbed pump power of 11.7 W,which corresponds to a slope efficiency of 85.5% and an optical-to-optical conversion efficiency of 48.9%.The wavelength tuning of the Yb:SSO laser pumped by the 976-nm LD is also investigated.The results show the tuning range from 1 002.30 to 1 068.47 nm,which corresponds to a tunability range of 66.17 nm.
