Device results are reported from channel guide InGaAs-GaAs strained quantum well lasers (lambda(L) = 980 nm) with In0.49Ga0.51P cladding layers. AR-HR coated channel guide lasers with a p-n-p InGaP current blocking junction on a p+-GaAs substrate show high output powers of 302 m W which is the highest output power obtained from InGaAs-GaAs-InGaP lasers.
