Abstract
High-power monolithically integrated broad area master oscillator powe r amplifiers (MBA-MOPA's) are fabricated consisting of a DBR laser, a preamplifier, a coherent beam expander, and a broad area power amplifi er producing up to 800 mW in a single spectral and spatial mode. The M BA-MOPA operates in an edge-emitting configuration with a primarily si ngle lobed output with a transverse beam divergence of 0.45-degrees in dicating a uniform phase over the 130 mum emitting aperture.
