By using two very different seed pulses we demonstrate that the spatio-temporal gain properties of a chi(2) optical parametric amplifier can be exploited as an efficient conical reshaping mechanism leading to the generation and amplification of a pulsed Bessel beam.

By using two very different seed pulses we demonstrate that the spatio-temporal gain properties of a chi(2) optical parametric amplifier can be exploited as an efficient conical reshaping mechanism leading to the generation and amplification of a pulsed Bessel beam.File in questo prodotto:
