Abstract

The invention provides a radiation source generation system based on pulse periodical phase modulation. The radiation source generation system can be applied to research about the transient dynamic process. The radiation source generation system based on pulse periodical phase modulation comprises a nanosecond pulse laser, a 2*2 optical switch, an adjustable time delayer, a broadband phase modulator, a gain compensation amplifier, a preamplifier, a main amplifier, a pulse compressor, an ultra-short laser pulse sequence, a pulse electron beam and an X-ray source pulse sequence. A repetitive pulse shaping narrow band nanosecond pulse generated by the nanosecond pulse laser enters an annular cavity formed by the adjustable time delayer, the broadband phase modulator and the gain compensation amplifier through the 2*2 optical switch, circulates for multiple times in the cavity and then is output as a periodical linear chirp pulse sequence; the periodical linear chirp pulse sequence is amplified in the preamplifier and the main amplifier and then is compressed by the pulse compressor to generate the ultra-short laser pulse sequence, and the ultra-short laser pulse sequence interacts with the synchronous pulse electron beam to generate the X-ray source pulse sequence.
