Описание: This video explains about emission process of laser.Laser emission relies on stimulated emission, where a photon strikes an excited atom, causing it to release a second, identical photon (same phase, frequency, direction), creating light amplification within a resonator cavity of mirrors, leading to a coherent, intense, monochromatic laser beam. This chain reaction requires population inversion (more excited atoms than ground-state) and a gain medium that stays excited long enough. #snsinstitutions #snsdesignthinkers #designthinking
