Abstract

Experiments on energy scaling and extending wavelength tunability of Dy:PGS and Dy:KPC lasers were undertaken. Both lasers demonstrated >1mJ output pulse energy under diode laser pumping. Dy:PGS laser wavelength tunability was extended to 4.68um, which is the longest wavelength of laser oscillation ever reported for this crystal under 1.7um diode pumping. The longest wavelength of laser oscillation with Dy:KPC crystal was 4.45um. Modelling of Dy:KPC and Dy:PGS laser operation in Q-switching mode was carried out. It was shown that Dy:KPC and Dy:PGS lasers are capable of producing Q-switch pulses with several kW peak power and pulse duration of ~ 40ns.
