Towards high energy 10 fs laser pulse via regenerative pulse shaping

The capability to generate few milliJoules, ultra-short laser pulses with robust and reliable systems has a fundamental importance for high harmonics generation and in general for attosecond physics. The technique we propose allows generating broadband spectra corresponding to laser pulse length of the order of lOfs or below. Using regenerative pulse shaping in addition with broadband optics, the complete oscillator bandwidth is almost recovered.
