Abstract

High-power single mode channeled-substrate-planar AlGaAs diode lasers are being developed for reliable, high-power operation for use as sources in spaceborne optical communications systems. Most work on AlGaAs semiconductor lasers has been focused on devices with an emission wavelengths less than 8400A where both high power and reliable operation have been previously demonstrated. In spaceborne communication systems, the output wavelength is optimized at 8700A to avoid absorption of the emitted light by the atmosphere when communicating with ground-based terminals. The CSP laser structure has been optimized for operation at an emission wavelength of 8700A. Such devices have exhibited output powers in excess of 80 mW cw at an operating temperature of 80 C. Single spatial mode and substantially single longitudinal mode operation has been obtained at output powers greater than 50 mW cw and 100 mW (50% duty-cycle). The phase-front of the high-power devices has been examined and has shown rms aberrations to be≈ λ/50. Lifetesting of these devices at 50mW (50% duty-cycle) has shown reliable operation in excess of 5,000 hrs.
