We present numerically calculated scattering, absorption, and backscattering efficiency factors of water particles for the quasi-white light field (radiation of a wide spectral range) produced due to self-focusing of a high-power femtosecond pulsed radiation in the atmosphere. These integral optical characteristics were studied for a wide range of drop sizes, covering the range of fog and cloud particles. The results obtained were compared with the scattering factors for a monochromatic radiation and the broadband radiation of a femtosecond pulse.
