S. Sato et al., Single-mode operation of broad-area diode laser at 670 nm by external cavity configuration with a diffraction grating, OPT REV, 7(6), 2000, pp. 573-575
We demonstrate the single mode operation of a broad-area diode laser at 670
nm by means of an external cavity configuration using a diffraction gratin
g. The output power of 150 mW is obtained with a spectral width of 40 MHz.
