Abstract

The holmium-doped yttrium orthovanadate (Ho:YVO₄) crystal was shown to be an effective solid-state saturable-absorber Q switch for a flash-lamp-pumped Tm,Cr:Y₃Al₅O₁₂ laser operating at 2.017 μm. A single Q-switched laser pulse of 3.5 mJ in energy and 45 ns in duration was observed with a 1-mm-thick 4% Ho:YVO₄ solid-state saturable absorber, which was grown with the high-temperature-solution-growth method.
