Description

technical field

[0001] The invention relates to a structure for compressing self-mode-locked pulses of fiber lasers, which uses fiber amplifiers to improve the output performance of fiber lasers, such as compressing the self-mode-locked pulses of fiber lasers, thereby realizing high-performance continuous fiber lasers, belonging to fiber lasers and Optical fiber amplifier technology field. Background technique

[0002] Fiber lasers working in continuous mode are being accepted by more and more applications due to their small weight and volume, high beam weight, stable and reliable performance, etc. However, continuous fiber lasers often produce multiple longitudinal modes because the optical cavity is excited by a disturbance factor or noise. These longitudinal mode pulses whose repetition frequency is determined by the length of the optical cavity will be strengthened because they pass through the gain medium multiple times. In the laser The output of the optical fiber is ...
