Abstract:
    The laser is composed of following parts connected through general optical fiber: laser pump source, wavelength division multiplexing coupler, ytterbium doped optical fiber, dispersion decrescent optical fiber with positive GVD, output coupler, mode-locking device of polarization rotation, compensating device for chatter pulse. The mode-locking device of polarization rotation includes polarization controller, isolator and polarization adjuster. The compensating device for chatter pulse consists of Bragg grating of optical fiber, and Faraday mirror. The invention can generate high energy, high power light pulse in femtosecond level, low cost, near to transform limit, with no base seat, and without chatter. The invention is applicable to optical fiber communication, nonlinear optics, super quick optics, and transient state optics widely.
