The holmium-doped yttrium orthovanadate (Ho:YVO4) crystal was shown to
be an effective solid-state saturable-absorber Q switch for a flash-l
amp-pumped Tm,Cr:Y3Al5O12 laser operating at 2.017 mu m. A single Q-sw
itched laser pulse of 3.5 mJ in energy and 45 ns in duration was obser
ved with a 1-mm-thick 4% Ho:YVO4 solid-state saturable absorber, which
was grown with the high-temperature-solution-growth method. (C) 1996
