Abstract

The experimental characterization of a high-power pulsed semiconductor laser operating in the eye-safe spectral range (wavelength around 1.5 mu m), with an asymmetric waveguide structure, a 100
m wide stripe, and a bulk active layer positioned very close to the p-cladding, is reported. An anti-reflection/high reflection coated laser with a stripe width of 100 um exhibits a single-facet output power over 25 W at a pumping current amplitude of 100 A.
