Experimental results on fast neutron generation in D(d,n)3He and T(d,n)4He reactions in the SOKOL-P laser facility [1] are presented. Solid targets were irradiated by 1.054 ${\rm\mu} $m, s- or p-polarized laser pulses of energy 5-8 J on target and duration 0.85-2 ps. The peak laser intensity was 0.5-2$ \cdot
$1018 W/cm2. Flat deuterated plastic (CD $_{2})_{\rm n}$ targets and Ti D $_{\rm\alpha }$T $_{\rm\beta}$ targets were used in experiments. Some experiments were carried out with additional targets placed in front of and behind the laser target. The used (TOF) time-of-flight technique helped identify neutrons from D(d,n)3He and T(d,n)4He reactions. Yields up to 106 DD-neutrons and 107 DT-neutrons were measured. Interaction of the fast ion beam with the target can explain the observed yield.
