The invention relates to an all-optical generator for ultra wideband and multi frequency pulse signals. The traditional pulse generator has high complexity and low system stability. The invention uses laser array with fixed wavelength interval and a carved and sub array laser in the laser wavelength corresponding reflected wavelength of fiber Prague grating, by each laser will respectively obtain ultra wideband single pulse signal Zhou Bo mentioned above, through the optimization and control of laser quantity, laser array of polarization and the output power of each part of the fiber Prague grating relative distance, through the photoelectric conversion speed of the photoelectric probe, which has high spectrum utilization rate Zhou Bo UWB pulse signal sequence in the U.S. Federal Communications Commission regulations. The invention has the advantages of low cost and low structure complexity, and is free from electromagnetic interference.
