Abstract

Tm and Ho doped solid-state lasers operate at 2-micron wavelength have many applications in medical, remote sensing, and military technologies. Using flash-lamp pumping, we demonstrated high-power Cr-Tm:YAG and Cr-Tm-Ho:YAG lasers at room temperature. The output energy in free-running operation exceeded more than 4 J. When an acousto-optic Q-switch was used, we obtained Q-switched single transverse-mode lasers at 2 micrometer wavelength. The maximum pulse energy of Cr-Tm:YAG and Cr-Tm-Ho:YAG lasers reached 0.7 J and 0.5 J, respectively, and the corresponding pulse widths were 140 ns and 165 ns.
