1. a mutual injected system that is used to produce the optics short pulse comprises a RF signal generator;

  • One the one FP laser diode and one the 2nd FP laser diode is characterized in that, also comprise;

    One power divider receives the power output that described RF signal generator is produced, and with the power separated into two parts that is received, and export a FP laser diode and the 2nd FP laser diode respectively to, in order to drive this two FP laser diodes;

    One coupler is connected between a FP laser diode and the 2nd FP laser diode;

    One erbium-doped fiber amplifier, the output of a FP laser diode exports this erbium-doped fiber amplifier to via this coupler, is used for power amplification;

    One adjustable light wave-filter is used for selecting from the light wavelength of this erbium-doped fiber amplifier output;

    One coupling device is injected into the light pulse of the selected wavelength of this adjustable light wave-filter in the 2nd FP laser diode with this required repetition rate, produces single wavelength pulse thus in the 2nd FP laser diode;

    AndOne variable light delay line, receive produce in the 2nd FP laser diode and through this list wavelength pulse of this coupling device coupling, its output is sent to a FP laser diode via this coupler, to encourage the emission of the single wavelength pulse in the FP laser diode.
