Abstract
Index-guided semiconductor lasers are used for many applications which require diffraction-limited output. The maximum output power of these devices determined by catastrophic degradation of the facet occurs at power levels of <200 mW. Additionally the mode stability of these devices has limited single transverse and longitudinal mode operation to <120 mW. We present data on real refractive-index guided lasers which emit up to 250-mW cw from a single facet, which is the highest output power reported to date from a single stripe laser. The diode radiates in a single longitudinal mode output at all power levels while radiating in the lowest-order transverse mode at power levels up to 150-mW cw.
