High power/energy thulium pumped holmium lasers

We describe the performance of unsensitized Ho:YAG lasers pumped by CW and pulse-pumped Tm:YLF lasers. The Tm:YLF lasers are diode-pumped. Thulium CW output power levels exceeding 40 W with M/sup 2//spl sim/1.35 have been achieved at 1.9 /spl mu/m. CW pumped repetitively Q-switched Ho:YAG 2 /spl mu/...

Zusammenfassung:We describe the performance of unsensitized Ho:YAG lasers pumped by CW and pulse-pumped Tm:YLF lasers. The Tm:YLF lasers are diode-pumped. Thulium CW output power levels exceeding 40 W with M/sup 2//spl sim/1.35 have been achieved at 1.9 /spl mu/m. CW pumped repetitively Q-switched Ho:YAG 2 /spl mu/m laser emission operating at room temperature has demonstrated 20 W at 10-20kHz with M/sup 2//spl sim/1.45.
