Paper Abstract

The generation of a temporary stable, TerraW, spectrally broadened laser beam with uniform wavefront is carried out through self-phase modulation in 3-mm Sa plate. The set-up for compression of the obtained spectrally broadened pulse is provided by 2x128 pixels Spatial Light Modulator (SLM) controlled by a genetic algorithm. The obtained ultrashort laser pulses have been characterized by an APE pulse measuring system SPIDER. The measurements show that the pulse length decreases more than 2 times: from 62 fs up to 28 fs. The new pulse shape is close to linear.
