Resonantly pumped tunable Ho:YAG laser

The efficient tunable Ho:YAG laser pumped by Tm:fiber laser of 20 W output power at 1908 nm was developed. For tuning the Lyot filter consisting of a quartz plate of 2.1 mm thickness was applied. The output power of 1.13 W for 3 W of absorbed pump power was reached at the wavelength 2132.8 nm. The tunability between 2075 – 2135 nm wavelength range was demonstrated.
