All-Polarization Maintaining Fiber Laser and Pulse Compressor

Fiber lasers have become one of the most important technologies in various industrial, medical, and scientific applications. However, their vulnerability to environmental disturbances, such as vibrations and thermal fluctuations, limits the range of practical operations outside the laboratory. In this letter, we report a simplified, all-normal dispersion, completely all-polarization-maintaining fiber integrated laser operating at 1030 nm. Our laser system employs a single-pump laser diode and an all-polarization maintaining fiber pulse compressor capable of generating 700-fs pulses with a pulse energy of 0.45 nJ.
