Description

technical field [0001] The invention relates to a dual-wavelength laser, which belongs to the field of fiber lasers, and more specifically relates to a dissipation soliton and soliton dual-wavelength laser based on a dispersion compensation fiber. Background technique [0002] Ultrashort pulse laser has a wide range of applications in optical fiber communication, biotechnology, medical treatment, laser spectroscopy, ultrafine processing, time-resolved spectroscopy and other fields. Mode-locking technique is a common method to obtain ultrashort optical pulses. Therefore, the research on mode-locked fiber lasers outputting femtosecond pulses has become a hot spot in the field of laser technology in recent years. Generally speaking, mode-locked fiber lasers can be divided into two categories according to different mode-locking methods: one is active mode-locked fiber lasers, and an intensity modulator or phase modulator driven by a microwave signal must be inserted into the ca...
