Spatio-temporal structure of femtosecond Bessel beams from spatial light modulators

Résumé

We numerically investigate the spatio-temporal structure of Bessel beams generated with Spatial Light Modulators (SLMs). Grating-like phase masks enable the spatial filtering of undesired diffraction orders produced by SLMs. Pulse front tilt and temporal broadening effects are investigated. In addition, we explore the influence of phase wrapping and show the spatio-temporal structure of SLM-generated femtosecond Bessel beams is similar to Bessel X-pulses at short propagation distance, and to subluminal Pulsed Bessel Beams at long propagation distance.
