Abstract
The efficient Q‐switched Ho:YAG hybrid laser resonantly pumped by a Tm:fiber (15 W CW @ 1908 nm) was developed. The performance of the laser was investigated for the operation both in free running and a Q‐switching regime. The output power of 3.5 W continuous‐wave (CW) for 10.2 W of incident pump power was reached at a wavelength of 2090.1 nm. In the Q‐switching regime an acousto‐optic modulator was applied. In the CW pumping regime the repetition rate was changed from 20 to 5000 Hz. For the best results, for a 20 Hz repetition rate, pulses of 2.5 mJ energy and 125 kW peak power were achieved. In this regime the shortest pulse of 19.07 ns FWHM was recorded. For the best case of Q‐switching in a quasi‐CW pumping regime (repetition rate of 20 Hz and a pulse width of 8 ms) the pulses of 127 kW peak power (2.8 mJ, 22 ns) were obtained.
