| Abstract(in English) | We demonstrate an off-axis external-cavity designed to yield a high-brightness, narrow-bandwidth emission from a high-power laser-diode array. This off-axis external cavity consists of a beam-transformation system and a volume Bragg grating. Using this external-cavity technique, a high-power broad-area laser-diode array operating at a drive current of 25A achieved a divergence angle of 2.3° and a bandwidth of 0.67nm with an output power of 14.9W. |
