Powerful techniques for spectral broadening and ultrabroad-band dispersion control, which allow compression of high energy femtosecond pulses to duration of a few optical cycles, are presented. Spectral broadening by propagation along hollow fiber filled with noble gases is studied under two excitation regimes with high energy input pulses of 140-fs and 20-fs duration respectively. With 20-fs input pulses and under optimum compression conditions we show a pulse shortening down to 4.5 fs with output energy up to 70 {mu}J using a high throughput prism-chirped mirror delay line.
