C. Svelto et I. Freitag, Room-temperature Tm : YAG ring laser with 150 mW single-frequency output power at 2.02 mu m, ELECTR LETT, 35(2), 1999, pp. 152-153
Efficient room-temperature operation of a diode-pumped Tm:YAG laser is demo
nstrated in a composite-cavity non-planar ring resonator. By longitudinal p
umping in continuous wave operation, a single-frequency output power up to
150mW and a multimode power greater than 0.5W are obtained for the Tm H-3(5
)-H-3(6) quasi-three-level transition at 2.02 mu m.
