In this work the cooling of the products of pulsed laser ablation of a tungsten target in vacuum, helium gas and in liquid superfluid helium was investigated by pyrometric measurements. It was shown that quantitative measurements of the characteristics of thermal emission make it possible to clarify the features of the mechanisms of the condensation processes of nanostructures in these media. The obtained data were used to calculate the cross sections of the emitting particles. It was shown that in vacuum mainly submicron particles emit, while in superfluid helium - nanoparticles. The results obtained are confirmed by the data of electron microscopy.
