Abstract

Diode-pumped Thulium thin-slab lasers have been demonstrated as attractive pumping sources for high-power 2 μm wavelength lasers with applications in defence and industry. We present a highly compact, power scalable, 1.9 μm wavelength Tm:LuLF thin-slab resonator using, for the first time, laser-machined freeform resonator mirrors, demonstrating the benefit of controlling the fundamental resonator mode sizes independently for the two resonator directions.
