Summary form only given. BW (broad-waveguide) SCH-QW lasers utilizing a thick undoped waveguide region (0.8-1.3 /spl mu/m) exhibit very low internal loss. The devices have very high differential efficiencies and record-high output power levels. The overall effectiveness of BW-SCH-QW approach has been demonstrated in five different material systems (AlGaAs-GaAs, AlInGaAsP-GaAs, InGaAsP-GaAs, InGaAsP-InP, and AlInGaAsSb-GaSb), thereby providing a method for achieving high output power within a wavelength range suitable for most medical and industrial applications.
