Ho: YLiF4 saturable absorber Q-switch for the 2-μm Tm,Cr:Y3Al5O12 laser

Passive Q‐switching of the flashlamp pumped Tm,Cr:Y3Al5O12 2‐μm laser with a Ho:YLiF4 saturable absorber has been demonstrated at room temperature. A single Q‐switched laser pulse of 11 mJ in energy and ∼45 ns in duration at 80 J flashlamp input energy was obtained. The wavelength of the Q‐switched laser output pulse and the Tm,Cr:Y3Al5O12 free‐running output was 2.017 μm.
