Abstract :
We report emission of a 100 mM cw beam into a nearly-diffraction-limited spot by a grating surface emitting (GSE) laser. The distributed out-coupled master oscillator power amplifier (DOC-MOPA) produces monochromatic (933 nm) narrow linewidth (10 MHz) beams and near-ideal far-field patterns. Single wavelength operation is demonstrated to 260 mW cw.
