Abstract: Continuous-wave laser action at similar to2 mum is demonstrated in a Tm-Ho:KYF4 single crystal at room temperature. Crystal growth, spectroscopic measurements, and laser results are presented. An output power in excess of 250 mW is obtained with a tuning range of 99 run, the largest ever published, to our knowledge, for Tm-Ho in any crystalline host. (C) 2004 Optical Society of America.
