摘要

Carrier-envelope phase (CEP)-stable sub-cycle mid-infrared (MIR) pulses play an important role to investigate field-sensitive nonlinear processes. In this contribution, we report the generation of sub-half-cycle phase-stable pulses with the carrier wavelength of( ω 1 ) and second harmonic (SH, ω 2 ) of sub-milli joule 35 fs pulses at 800 nm were focused into nitrogen gas at∼10m through two-color filamentation in nitrogen [1]. The fundamental atmospheric pressure. Broadband MIR pulses ( ω 0 ) were generated through the four-wave mixing (FWM) process, ω 1 + ω 1 - ω 2 ω 0. Typical MIR spectra at four different phase delay lengths between the fundamental and SH.2m. The input pulses are shown in Fig. 1(a). The center of mass of the spectrum at zero phase delay lengths is 10 spectrum is spread from 4.90 to 43.1m (from 2040 to 232cm- 1 ), which corresponds to more than three octaves with full width at tenth maximum. The pulse energy was 0.42J, which would be high enough for high harmonic generation in solids.
