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 higherorder 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 fdled with a noble gas.
