Brief summary

There are presented results of experimental investigations of conditions for an observation of a partitioning of ballistic and scattered components in temporal distributions of ultrashort laser pulses passed through homogeneous layers of the model high scattering biological medium. The range of the existence of bimodal temporal distribution has been experimentally determined. The combination found for parameters of an initial pulse and characteristics of a high-scattering medium made it possible to provide conditions for generation the bimodal form of the temporal distribution of transmitted radiation.


Key words

ultrashort laser pulses, high-scattering biological medium, bimodal temporal distribution, radiation propagation through the substance, radiation transport equation
