Tm:KLu(WO(4))(2) microchip laser Q-switched by a graphene-based saturable absorber

Opt Express. 2015 Jun 1;23(11):14108-13. doi: 10.1364/OE.23.014108.

Abstract

We report on the first Tm-doped double tungstate microchip laser Q-switched with graphene using a Tm:KLu(WO4)2 crystal cut along the Ng dielectric axis. This laser generates a maximum average output power of 310 mW with a slope efficiency of 13%. At a repetition rate of 190 kHz the shortest pulses with 285 ns duration and 1.6 µJ energy are achieved.
