We present a pulse compression scheme for the characterization and shaping of a two-colour pumped optical parametric chirped pulse amplified (OPCPA) laser system with spectra comprising of 1.5 octaves (from 430nm-1300nm; Fourier limit: sub-3 fs). A prism and an LCD spatial light modulator in a 4-f scheme is the base of our setup. Multiphoton intrapulse interference phase scan (MIIPS) is based on such an apparatus and is the most promising method to control the spectral phase. The study of the range of the needed specifications is being conducted, where theoretical simulations have been performed. This method has the advantage of both characterizing and compressing a pulse simultaneously through the use of a relatively simple setup.
