Abstract

We experimentally generate optical vortices in the output beam of a Ti:sapphire laser emitting 20-fs pulses. Screw phase dislocations are imposed in each spectral component of the short pulses by aligning computer generated hologram within a 4f-setup. The analysis shows that phase dislocations can be generated also at the stage of femtosecond pluse compression.
