Abstract: The modelling of interaction of ultra-intense femtosecond laser pulses with deuterated polyethylene targets is carried out with the processes of multiple field ionisation of the target atoms and the emission of neutrons produced in the course of the fusion reaction at high-energy deuteron collisions taken into account. The possibility of essential increase in the neutron yield (by tens of times) when using layered deuterated polyethylene targets with optimal dimensions of the layers and interlayer separations ~1 mm is demonstrated.

Keywords: laser plasma, field ionisation, neutrons, layered target.
