Direct space-to-time femtosecond pulse shaping based on 2D phase-only spatial light modulator
Résumé
We present a very compact revisited DST-PS by using a phase-only 2D LC-SLM, without additional grating and mask. For conventional DST-PS, output pulse is directly repeating the form of a shaping mask which is imaged onto a passive diffraction grating. We introduce the following innovative feature: computer controlled reflective phase only LC-SLM with high spatial resolution (i.e. 8μm) can act as an inhomogeneous programmable blazed phase grating.
