Abstract

A femtosecond pulse train with THz repetition rate generated by the interference of two phase-modulated pulses has been recorded experimentally. Pulse repetition rates and their duration have been measured. It has been shown that at the 50-fs time delay between phase-modulated pulses the repetition rate is 3.1 THz with a pulse width of 200 fs, while at the 120-fs time delay the repetition rate is 7.1 THz with a pulse width of 67 fs.
