Meanwhile, we also design a feedback circulator to make the active mode-locking fiber laser system stable which can control PZT to modify the fiber ring cavity and generate an ultralow timming jitter fiber laser. Later, we use DCF to compensate the dispersion and enlarge the average power and further take the advantage of the soliton compression to transform the pulse width from picosecond into femtosecond scale. In this project, we estimate this system can generate a fiber laser with the pulse width of <500 fs, the repetition rate of 10 GHz, output power from 1 to 100 mW, wavelength of 1550 nm, timming jitter of <100 fs and linewidth of >7 nm.主動鎖模光固子active mode-lockingsoliton
