Abstract
A high-speed linear wavelength-swept laser source working at center wavelength of 1309 nm is demonstrated. Wavelength tuning is performed using a compact polygon filter in Littrow telescope-less configuration. The repetition frequency of the wavelength-swept laser source is up to 50 kHz with the polygon scanned at a speed of 694 rotations per second. The turning range is 130 nm and full width at half maximum (FWHM) is 61 nm. The average output power can reach to 7 mW. The developed swept laser source can be implemented in optical frequency domain imaging, optical reflectometry, and other test or measurement applications.
