摘要：

Laser operations in the continuous-wave as well as in the pulsed regime of a 4 at.% Tm3+: CaF2 crystal are reported. For the continuous-wave operation, a maximum average output power of 1.15 W was achieved, and the corresponding slope efficiency was more than 64%. A continuous tuning range of about 160 nm from 1877-2036 nm was achieved using a birefringent filter. Using Argentum nanorods as a saturable absorber, the significant pulsed operation of a passively Q-switched Tm3+: CaF2 laser was observed at 1935.4 nm for the first time, to the best of our knowledge. A maximum output power of 385 mW with 41.4 mu J pulse energy was obtained under an absorbed pump power of 2.04 W. The present results indicate that the Tm3+: CaF2 lasers could be promising laser sources to operate in the eye-safe spectral region.
