A diode-pumped Ho:Tm:YLiF4 laser at room temperature has achieved an optical efficiency of 5.9% under normalmode operation. Long pulse lengths, of the order of 1 µs, have been obtained by use of 4-m ring resonator, with laser energy output of 15 mJ in single Q-switched pulses for an input energy of 2.078 J.
