Abstract
We demonstrate that appropriately designed external cavities can be used to frequency narrow high-power diode-array bars. Using a commercial 20-W arra y, we narrow the linewidth to 50 GHz with 14 W of cw output power. A magnif ying telescope and a cylindrical collimating lens minimize broadening owing to curvature in the alignment of the diode-array elements. (C) 2000 Optica l Society of America.
