Abstract:
A new version of the method for spatiotemporal smoothing of laser radiation using spectral dispersion is proposed, which does not require the use of high-frequency phase modulators, i.e. a method based on the use of a broadband master oscillator. An experimental study of this method has been conducted on the Luch laser facility.
Keywords:
smoothing of laser radiation, spectral dispersion, uniformity of target irradiation, partially coherent radiation, speckles.
