Performance of graded-index separate-confinement heterostructure single quantum well lasers especially designed for cw optical-pumping applications is reported and is compared to that of conventional double-heterostructure devices. The quantum well devices have the advantage of lower threshold current, higher slope efficiency, and can be operated at longer cavity lengths, leading to lower diode-series resistance and reduced cooling requirements. Quantum wells of aluminum composition ranging from 6.7% to 12% and thicknesses of 12 and 20 nm were investigated. Useful lasing wavelengths between 780 and 820 nm were achieved.
