Abstract

The holmium-doped calcium fluoride 1Ho:CaF22 crystal was shown to be an effective solid-state saturable-absorber Q-switch for a flash-lamp-pumped Tm, Cr:Y3Al5O12 laser at 2.017 μm. With a 1–cm-thick Ho(0.5%), Er(5%):CaF2 saturable absorber and a 6.3% output coupler, a single Q-switched laser pulse of 51 mJ in energy and 60 ns in duration was obtained at a flash-lamp input energy of 85 J. With a 14.6% output coupler, a typical Q-switched laser pulse of 84 mJ and 82 ns was observed.
