METHOD FOR FORMING SYNCHRONOUS SEQUENCES OF ULTRASHORT LASER PULSES AND FEMTOSECOND LASER COMPLEX Russian patent published in 2017 - IPC H01S3/23 

FIELD: physics.

SUBSTANCE: method for forming synchronous sequences of ultrashort laser pulses with different wavelengths, is that: the first sequence of ultrashort laser pulses is generated; the first sequence is used as a pumping source for generating the second sequence of ultrashort laser pulses; the shift of the spectrum generating the second sequence of ultrashort laser pulses is tracked, and(or) the magnitude of phase mismatch of the first and the second sequences of ultrashort pulses is determined, and a correction signal is produced to correct the displacement spectrum and(or) to minimize the magnitude of phase mismatch with the purpose of adjusting the repetition frequency of the pulses of the second sequence of ultrashort laser pulses.

EFFECT: providing the possibility of increasing the power of synchronous sequences of ultrashort pulses without the use of hazardous substances.
