Abstract

This report presents the activity developed on laser pulse shaping argument in years 2004-2005 by Milano-INFN within the framework of CARE /JRA2 \Charge production with Photoinjectors" second task \Pulse Shaping". A dedicated laser system with the relative diagnostic tools have been developed. A liquid crystal programmable spatial light modulator(LCP-SLM) shaper have been studied and set for the generation of di®erent waveforms. The shaper is integrated in the laser system for an automatic generation of the target waveforms via the insetion of a computer which drives the system through the developed software. The system can be programmed to generate any target waveform compatible with the spectral bandwidth of the laser system and some exemples are presented. The following issues are treated: (i) the operation stability as function of perturbations of the set-up parameters, (ii) the design of the shaper for the SPARC project, (iii) a new shaper concept for the generation of long target waveforms and (iiii) the rectangular pulse generation at the second harmonic.
