A growth technology has been developed, and a Tm:Ho:Yb{sub 3}Al{sub 5}O{sub 12} laser crystal of high optical quality has been grown by Czochralski method. Its spectral and luminescent characteristics are studied. Lasing at a wavelength of 2100 nm is obtained under pumping into the absorption line on the {sup 3}H{sub 6} – {sup 3}F{sub 4} transition of the Tm{sup 3+} ion at a wavelength of 1678 nm. The slope and total (optical) efficiencies of the laser at an output power of up to 320 mW reach 41% and 30%, respectively. (lasers)
