Single longitudinal mode lasing of Tm,Ho:YAP microchip laser at 2000.4 nm

Single-longitudinal-mode operation of a b-cut Tm(5%), Ho(0.3%):YAlO3 microchip laser is reported. An incident pump power of 1.85 W is used to generate the maximum single-frequency output power of 30 mW at 2000.4 nm, which represent a 1.6% optical-to-optical conversion efficiency. To the best of our knowledge, this is the first time to report on single-frequency operation in Tm,Ho:YAP lasers.
