Abstract:
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.
Keywords:
ZrO2 – Y2O3 – Ho2O3 crystals, two-micron lasing, Q-switched regime.
