Abstract
A widely tunable Holmium-doped Sc2SiO5(SSO) 2 μm laser is reported in this manuscript, which has a wavelength tunable range of 110 nm (from 2050 to 2160 nm). A maximum output power of 3.02 W at 2111 nm is obtained when the laser operates on the continuous-wave free-running mode. A birefringent filter is used to realize the output wavelength tuning, which is put into the laser resonant cavity. The maximum output power of the tunable Ho:SSO laser is 2.07 W. It is the first time to report a widely tunable Ho:SSO laser. The wavelength tunable range is wider than the ones of other Ho-doped lasers and the output power is higher too, which could extend application fields of the Ho-doped lasers.
