We narrowed the spectral bandwidth of our 2 W broad-area laser to 8 ± 1   GHz with a coarse tunability of 12   nm centered near 790   nm in an external cavity. Our passively stabilized external cavity was designed for use with high-power semiconductor lasers. The cavity length and mount are modular with a fixed pivot point so that the optical elements can be changed to access a broad frequency spectrum and enable multiple applications. The bandwidth was observed to be dependent on the multimode transverse structure of the laser.
