Recent experiments at the laser facility PALS focused on the laser driven fusion of deuterons are reviewed. They benefit of high reaction cross-sections and of a high number of multi-MeV deuterons from thick CD2 targets irradiated by intensity of 3x10(16) W cm(2). In the reported experiments fast fusion neutrons with energy up to 16 MeV were produced through Li-7(d, n)Be-8 and B-11(d, n)C-12 reactions in a pitcher-catcher target configuration. When using a large area CD2 foil as a secondary catcher target the total maximum neutron yield from the H-2(d, n)He-3 reaction increased by a factor of about 5, from 4x10(8) to 2x10(9). This result reveals that most of the deuterons having enough kinetic energy to enter a fusion reaction are emitted from the primary target into vacuum.
