Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with specific embodiments.
[0025] refer to figure 1 , a device based on Peregrine solitons using saturable absorbers to generate high-quality pulses, including: Peregrine soliton generators 1, saturable absorbers (SA) 2, erbium-doped fiber amplifiers (EDFA) 3, standard single-mode fiber (SMF) 4 , an isolator (ISO)5, a polarization controller (PC)6, a high dynamic range optical spectrum analyzer (OSA)7 with 2.5GHz resolution, and an ultrafast optical sampling oscilloscope (OSO)8 with sub-picosecond resolution. The Peregrine soliton obtained by the Peregrine soliton generator 1 is input into the saturable absorber (SA) 2, and the background wave of the (PS) is eliminated by using the saturable absorber, and then the Peregrine soliton of eliminating the background wave is sent into the erbium-doped fiber amplifier ( In EDFA)3, after amplification, the power of the Peregrine soliton reaches 2P 0 (P0 ...
