Abstract

Beam-quality measurements on the output of a 915-nm AlGaAs-InGaAs-GaAs slab-coupled optical waveguide laser (SCOWL) are reported. This device had a nearly circular mode (3.8 μm by 3.4 μm 1/e² widths in the near-field) and was capable of a single-ended continuous-wave output power of greater than 1 W. Measurements of M² indicate that the SCOWL output beam is nearly diffraction-limited in both directions with M/sub x/² /spl sim/ M/sub y/² /spl sim/ 1.1 over the entire range of output powers measured.
