Abstract :
Room temperature, continuous wave operation of laser diodes with an emission wavelength of 633 nm at output powers of 900 mW from a single 100 mu m wide stripe and 3 W from a monolithic 1 cm bar are reported. A threshold current density of 400 A/cm2 and external differential quantum efficiency of 44% were obtained from 100 mu m wide broad-area lasers.
