Abstract:

This chapter focuses primarily on progress in HPDLS that are grown on GaAs substrates and emit in the operating wavelength range λop = 900... 1000 nm, where the highest performance is reported, and the majority of studies are performed. Our discussion starts with a review of progress in broad area BA-HPDLs that reach the very highest powers and efficiencies, at the cost of degraded beam quality.
