Paper Abstract

Cascade pumping of type-I quantum well gain sections led to increase of the output power and efficiency of GaSb-based diode lasers operating in spectral region from 1.9 to 3.3 µm. The wide stripe multimode lasers based on cascade lasers heterostructures generate watt class output power levels up to 3 µm. The corresponding narrow ridge single spatial mode and single frequency mode distributed feedback devices generate tens of mW. The external cavity lasers utilizing gain chips based on cascade diode laser heterostructures demonstrate extra wide tuning range. The short pulse passively mode-locked lasers generate optical frequency combs.
