cw power conversion efficiencies of 57% have been obtained on uncoated diode lasers emitting nearly 300 mW per facet. This performance is achieved by using a low-resistance graded index separate confinement single quantum well AlGaAs/GaAs structure with high (84%) differential quantum efficiency and low threshold current.
