We report -switched energy output from a Ho:YAG oscillator, resonantly pumped at by a diode-pumped Tm:YLF laser. We demonstrate a -switched-to-normal-mode extraction efficiency of 100% at an output energy of 30 mJ and over 64% at the 50-mJ output level. Operating at 50 mJ (60 Hz) of output, a pulse width of 14 ns is achieved from the holmium oscillator, which corresponds to of peak power. At the 50-mJ output level, a beam-propagation factor is achieved.
