- Abstract
- The results of the experiments on dynamics of filamentation of high-power ultrashort Ti:Sapphire-laser pulses with the wavelengths of 800 and 400 nm during their sharp focusing in air are presented. The dependences of position and dimensions of a plasma channel formed in nonlinear beam focus zone on laser pulse power are obtained. The laser pulse spectra during its filamentation are measured.
