Abstract
Were experimentally investigated nonlinear optical effects at propagation of laser pulses with length of a wave 0,82 microns and duration 80 fs in liquid aerosols and the drops containing organic dyes. Frequency of recurrence of laser pulses of 90 MHz, energy in a pulse 3,5 nJ, average capacity of radiation up to 340 mW. Registration of spectra of stimulating radiation and a luminescence of a drop was carried out with the sanction of 0,3 nanometers. Capacity of radiation varied turn of Glan prism. Results of measurements doublephotons are submitted to the excited luminescence in the suspended millimetric drops with dye and with filling nanoparticles of silver. Factors transparent and absorbing aerosol environments for laser continuous and fs radiations with length of a wave 0,82 microns and on length of a wave of continuous probing radiation with length of a wave 0,63 micros are received. Dependences of factor transparent the aerosol environment from concentration of an aerosol and capacity of laser pulses are submitted. Comparison of distribution of laser pulses fs duration with distribution of continuous radiation of the same length of a wave is carried out. Optical breakdown on absorbing particles of the aerosol environment is fixed at capacity of influencing radiation with fs duration exceeding 200 mW.
