>25 W pulses from 1.5 <em>µ</em>m double-asymmetric waveguide, 100 <em>µ</em>m stripe laser diode with bulk active layer

Abstract

<div lang="en" class="abs"><p class="abs_header">Abstract</p><p>The experimental characterization of a high-power pulsed semiconductor laser operating in the eye-safe spectral range (wavelength around 1.5 𝜇m), with an asymmetric waveguide structure, a 100 𝜇m 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 𝜇m exhibits a single-facet output power over 25 W at a pumping current amplitude of 100 A.</p></div>
