HO-YVO4 SOLID-STATE SATURABLE-ABSORBER Q SWITCH FOR A 2-MU-M TM,CT-Y3AL5O12 LASER

摘要

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 mu m. 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.
