We present an experimental study of emission of relativistic electrons, fast ions and DD-fusion neutrons produced by interaction of sub-nanosecond laser radiation with solid targets performed at the PALS facility. Measurements of electron density close to the target surface using the femtosecond interferometry, energy distribution functions of hot electrons far from the target, and time-of-flight spectra of ions are performed. A multi population of electrons is formed as the laser interaction with plasma proceeds. Ions accelerated by hot electrons to MeV energy are emitted in bursts. The neutron yield from the deuterated target is compared to yields obtained from other experiments. Constraint of non-linear processes on the ion acceleration and resulting neutron yields is shown.
