Paper Abstract

Frequency swept laser sources have various applications, such as LIDAR, spectroscopy, sensing. We demonstrate a 1.5-μm frequency-sweepable single frequency fiber laser in this work. By modulating the intensity of the pump, photo-induced refractive index change occurs in the gain fiber and the free spectral range of the laser is improved. As a result, the frequency sweeping can be realized. The DBR structure is employed to ensure the single-frequency operation. The central wavelength and the maximum sweeping range is measured to be 1550.25nm and 800MHz, respectively. A repetition rate up to 1kHz with an average output power of 0.6mw is realized.
