Compression of High Energy Laser Pulses by the Hollow Fiber Technique — •Orazio Svelto, S. De Silvestri, and M. Nisoli — Dipartimento di Fisica, Politecnico, P.zza L. da Vinci 32, 20133 Milano ITALY

A novel laser-pulse compression technique, which is particularly suitable for compressing femtosecond pulses of high energy (millijoule) and for providing large compression ratios, will be presented. The technique essentially relies, for spectral broadening, on the use of a hollow fiber made of fused silica and filled with noble gases at high pressure. Pulse energies to several hundreds of microjoules with pulse duration well below 10 fs will be reported. Applications of these pulses for exciting coherent oscillations in color centers will be presented and prospects for high-order harmonic generation will be discussed.
