Engineering Physics Annotation << Back The Conical Structure of the Laser Beam Behind the Output Window of the Cuvette With an Almost Resonant Medium Ogluzdin V.E. The purpose of this work is to show that in the process of interaction of a laser beam with a resonant medium considered on the basis of a corpuscular model, leading to the appearance of a conical structure outside the output window of the cuvette, axions and three photons participate along with photons, Based on the results obtained in the work on the interaction of photons and axions with atoms of a dispersed medium, the possibility of explaining the blue color of the morning sky and the red color of the evening sun. Keywords: photon, axion, triphoton, Cherenkov-Vavilov radiation, dispersed medium, blue-blue color of the sky, red color of the evening sun. DOI: 10.25791/infi zik.2.2024.1384 Pp. 17-23.
