Abstract

Array-specific propagation effects are relevant for evaluating cross-talk or coherent coupling in multichannel processing and designing complex interference maps. At pulse durations in few-cycle range, an important goal is to combine the flexibility of shaping structured beams with a high-quality temporal transfer. Therefore, low-dispersion actuator arrays have to be applied in a diffraction-free approach. Flexible structuring of sub-3-cycle Ti:sapphire laser pulse arrays was studied with collectively or individually tunable liquid crystal devices and thermally actuated mirrors. It is shown that the classical diffractive Talbot effect can be complemented by the spatio-temporal self-imaging of pulsed nondiffracting needle beam arrays.
