Аннотация:We propose an approach to stabilize the parameters of filament-generated infrared light bullet against pulseto-pulse fluctuations in three domains: spectral, spatial and energy, by means of amplitude modulation of theinitial laser beam. We studied the single-shot angle–wavelength spectra of filament-generated supercontinua fora beam modulated by a four-hole opaque mask and a beam without additional modulation. We demonstratedthat amplitude modulation of the initial beam improves the bullet pulse-to-pulse stability in all the threedomains with the bullet energy stability reaching as high as fivefold enhancement.
