Soliton pulse compression in the single-cycle regime in dielectric-coated metallic hollow waveguides

Abstract

During the last two decades impressive progress has been achieved in the generation of intense few-cycle pulses. A well-established technique for few-cycle pulse generation is based on the application of noble-gas-filled dielectric hollow waveguides using the combination of spectral broadening by self-phase modulation and pulse compression by negative group delay. An alternative technique for compression of ultrashort pulses relies on the method of soliton compression [1] using the periodic evolution of the temporal shape and spectrum of higher-order solitons in the anomalous dispersion region. In this contribution we show that this technique can be applied for the generation of single-cycle pulses in hollow metallic dielectric-coated waveguides filled with a noble gas.
