DEVICE FOR THE AMPLITUDE AND PHASE PROGRAMMING OF LONG-SPEED LIGHT PULSES WITH A NARROW SPECTRAL BAND FROM A MODULATOR OF WIDE BULB PULSES WITH A BROAD SPECTRAL BAND

摘要

Device for the adaptation of a programmable shaper of ultrashort light pulses with broad spectral band, to long light pulses with a narrow spectral band, knowing that it comprises: a laser source (1) of ultra short pulses wide spectral band, - a device for dispersing (2) ultrashort pulses originating from the aforesaid laser source (1), - a first nonlinear optical mixer (4) for mixing the modulated long pulses originating from the aforesaid dispersing device ( 2) with quasi-monochromatic long signals from a pure frequency pump laser (3), - a spectral broadband light pulse shaper (5) placed on a first channel (V1), - a second optical mixer (6) nonlinear for mixing the channel from the aforesaid shaper (5) and a second channel (V2) emerging from the aforesaid first nonlinear optical mixer (4).
