The energy and time characteristics of Q-switched two-micron lasing at the ⁵I₇ → ⁵I₈ transition of Ho³⁺ ions in ZrO₂ – Y₂O₃ – Ho₂O₃ crystals are studied under resonance pumping to the ⁵I₇ level by a cw Tm : LiYF₄ laser. The mechanisms of appearance of burns on the faces of the ZrO₂ – Y₂O₃ – Ho₂O₃ active elements at high laser energy densities are proposed.
