Abstract

Laser sources in the mid-infrared (MIR 3 - 5 μm) are increasingly in demand to meet the needs of a variety of applications which exploit the strong ro-vibrational molecular absorption lines in this spectral region. Requirement of high energy pulsed light is found in time-resolved sensing applications such as LIDAR. Fiber lasers in the midinfrared are promising candidates for generating such pulses, with Q-switched erbium-doped systems demonstrated covering both the 2.8 μm and 3.5 μm bands. However, there remains a sizable ‘gap’ in spectral coverage of such lasers, motivating interest in pursuing alternative rare earth dopants. Dysprosium in particular is a compelling solution, as it possesses a wide gain bandwidth covering 2.8 to 3.4 μm with recent electronically tunable systems closing much of this ‘gap’.
