Femtosecond lidar system: Application for research of the interaction of the high-power laser radiation with different media

The propagation of the high-power terawatt femtosecond laser radiation via different media has been represented. Experimental work has been done using femtosecond laser system IAO SB RAS based of the Ti:Sa laser. It has been showed the applicable of the beginning of the lilamentation region, angle of the divergence of the conical emission of the supercontinuum with the interaction with different media.
