Intensity-correlated spiking infrared and ultraviolet emission from sodium vapors
Published 18 Jan 2021 in physics.optics, physics.atom-ph, and quant-ph | (2101.06904v2)
Abstract: The directional spiking infrared and ultraviolet emission from sodium vapors excited to the 4D5/2 level by a continuous-wave resonant laser pump, that constitute a novel feature of the cooperative effects, has been analyzed. Cascade mirrorless lasing at 2207 and 2338 nm on population-inverted transitions and ultraviolet radiation at 330 nm that is generated due to four-wave mixing process demonstrate a high degree of intensity correlation.
