High-Power Diode-End-Pumped Slab Composite Tm:YLF Compact Laser

Journal of Russian Laser Research Aims and scope

Abstract

We design a continuous-wave Tm:YLF laser with a composite slab crystal end-pumped by two fiber-coupled laser diodes at room temperature. We achieve a maximum continuous wave output power of 105 W for the bonded slab Tm:YLF laser; the corresponding slope efficiency is 47.7% and the optical-to-optical conversion efficiency is 42.0% with respect to the incident pump power. The laser operated at 1,907.5 nm with a beam quality factor of M2 ∼3.2 at the highest output power.
