Paper Abstract

Index-guided channeled-substrate-planar (CSP) AlGaAs diode lasers are being developed for reliable, high-power operation for use as sources in spaceborne optical communications sytems. Although most work on this AlGaAs structure has been aimed at optimizing preformance at output wavelengths less than 8400 Å, emission in the 8700 Å regime is also of interest. In particular, such wavelengths are required for use in the Direct Detection Laser Transceiver (DDLT), to be incorporated into NASA's Advanced Communications Technology Satellite (ACTS), in order to avoid absorption of the light by the atmosphere when communicating with ground-based terminals. Lowest order spatial mode and substantially single longitudinal mode output has been ob-served in 0.87 pm CSP devices in excess of 50 mW cw and 100 mW 50% duty-cycle, with rms phase-front aberrations measured to be = λ/40.
