Abstract
Device for adaptation of a programmable generator of ultra short wide spectral band light pulses, to long narrow spectral band light pulses comprising a laser source (1) of ultra-short wide spectral band pulses, a device (2) for dispersion of ultra-short pulses output from said laser source (1), a first non-linear optical mixer (4) to mix long modulated pulses output from said dispersion device (2) with long quasi-monochromatic signals output from a pure frequency pump laser (3), a generator (5) of wide spectral band light pulses placed on a first channel (V1), a second non-linear optical mixer (6) to mix the channel output from said generator (5) and a second channel (V2) emerging from said first non-linear optical mixer (4).
