Paper Abstract

A white light continuum of octave spanning was produced by self-phase modulation in a hollow-core fiber filled with noble gases at high pressure and subsequently compressed by a set of ultra-broadband chirped mirrors. Pulses as short as 5.1 fs with energy up to 400 μJ at a 1 kHz repetition rate were obtained. Based on the carrier-envelope phase (CEP) locking of the femtosecond oscillator and the spectral interference of the white light continuum between the white fundamental wave and the harmonic wave at the same wavelength, the CEP of 5.1 fs pulse can be further locked by modulating the pump laser through a slow loop. The intense, few-cycle laser pulses with a stable CEP will enable us to produce high-order harmonic X-ray laser by the interaction with a rare gas target, this may drive the individual attosecond pulse generation.
