Abstract
Recent advances in ultrafast laser technology have led to the generation of light pulses comprising few optical cycles employing different compression techniques. In particular, two techniques have been developed, which allow addressing the issues of high peak power or frequency tunability in a wide spectral range, namely: the hollow-fiber compression technique and the opt ical parametric amplification. This paper analyzes the general scheme of pu lse compression and reports on the most interesting results obtained using the above-mentioned techniques. The combination of spectral broadening in a gas-filled hollow fiber with ultrabroad-band dispersion control, has led t o the generation of pulses with duration of similar to5 fs with peak powers up to 0.11 TW. Using optical parametric amplifiers with different configur ations sub-15-fs laser pulses have been generated tunable in the visible an d in the near-infrared.
