Visible laser diodes emitting at 672 nm and employing a GaInP strained-layer, single quantum well, graded-index separate confinement heterostructure (GRINSCH) design have been fabricated. CW output power in excess of 1 W and CW threshold current density as low as 305 A/cm2 were obtained from a coated, 60-mu-m wide oxide stripe diode operating at 10-degrees-C.
