title = "1-W Single-Mode Edge-Emitting DBR Ring Oscillators",
abstract = "The distributed Bragg reflector (DBR) ring oscillator is a new class of single-mode diode laser which emits high power, spatially coherent, single frequency output from a large aperture. An edge emitting Dbr ring oscillators has been fabricated that exhibits single frequency operation to 1 W output from a single facet. From a second device, the far field radiation pattern is a 0.2° diffraction-limited beam which remains stable and stationary up to 460 mW, measured from an uncoated facet. This device produces over 2.5 W of coherent power into four equal beams and has a threshold current density of 177 A/cm2 and a differential quantum efficiency of 63%.",
