Abstract
A system for generating short optical pulses having a very high temporal contrast at a wavelength λ, includes: a generator of optical pulses B1 outputting pulses at a wavelength substantially equal to λ; a generator of optical pulses P, B2 outputting pulses at a wavelength substantially equal to 2*λ3; a device R for recombining the pulses from the generators; a parametric amplifier A receiving the output of the recombination device R as an input; a filter F2 extracting, from the output of the parametric amplification device A, a band centered about a wavelength equal to 2*λ; a second harmonic generator NL receiving the output of the filter F2, at the input; a filter F3 centered about a wavelength equal to λ, extracting the second harmonic wavelengths of the pulses produced by the second harmonic generator NL.
