Abstract
High power, high efficiency diode lasers operating in the 15xx nm wavelength range are needed for a variety of applications, including eye-safe infrared illuminators and resonant diode pumps for Erbium-based high energy laser systems. We have demonstrated high power, high efficiency lasers at 1532 nm with integrated wavelength control. We have engineered the epitaxial structure in InP to mitigate losses and to include a buried distributed feedback (DFB) grating layer for wavelength control. We have demonstrated 15xx nm lasers generating >3 W at 36% EO efficiency. We have also demonstrated multi-Watt DFB broad area lasers with >99% of the power concentrated in a narrow spectral width <1 nm. These lasers are being packaged into fiber-coupled modules.
