Notes: An external-cavity tapered diode laser utilizing fiber Bragg grating feedback was designed to oscillate on a single-longitudinal mode. Stable single-longitudinal mode operation was attained at powers as high as 1.35 W. The emission frequency tuned smoothly with current over the cavity's free spectral range of 6 GHz. The power in the lasing mode was 〉30 dB above the background amplified spontaneous emission and the side-mode suppression ratio was 〉15 dB. No deterioration in the beam quality was measurable up to the highest output power. The coupling efficiency into a Gaussian resonator mode was 〉65% up to 1.35 W. © 1998 American Institute of Physics.
