- 論文の詳細を見る
We demonstrate a high-brightness, narrow-bandwidth, broad-area laser diode with a rear external cavity that consists of a micro-cylindrical lens and a volume Bragg grating in the rear facet of the diode. Using this external-cavity technique, a broad-area laser diode achieved a bandwidth's full width at half-maximum (FWHM) of 0.22 nm and a divergence angle (FWHM) of 1.1° with an output power of 446 mW.
