Abstrakt: We report on the performance of a 100 W, 105m, 0.17 NA (filled) fiber-coupled module operating at 976 nm. Volume holographic (Bragg) gratings are used to stabilize the emission spectrum to a 0.2 nm linewidth and wavelengthtemperature coefficient below 0.01nm/°C with virtually no penalty to the operating power or efficiency of the device. The typical fiber coupling efficiency for this design is >90%, enabling a rated operating efficiency of ~50%, the highest reported for a 100W/105m-class diode pump module (wavelength stabilized or otherwise).
