A Laser-Diode-Pumped Widely Tunable Single-Longitude-Mode Tm:YAP Laser at Room Temperature

A laser-diode-pumped widely tunable single-longitude-mode Tm:YAP laser
in 2μm eye-safe region is built. Continuous tunable range from 1899nm
to 2025nm is achieved with the maximum laser output power of 225mW at
1989nm. In addition, the Tm:YAP laser operating under multimode and
single-mode conditions is discussed.
