The Development of Chemically Pumped Visible Lasers from Efficient Electronic Energy Transfer.
Abstract
Visible chemical laser amplifiers have been generated in select wavelength regions near 527, 492, and 460 nm employing the highly efficient and selective formation of sodium dimer electronically excited states from the sodium trimer-halogen atom (x=C1, Br, I) reactions. With a focus to increasing amplifier gain length and amplifying medium concentration, an extended path length slit source device has been constructed which created intersecting alkali ahd halogen sheaths forming the basis for the development of a visible chemical laser oscillator. This device has now revealed the first Raman pumping resulting entirely from a chemical reaction, the process being observed in the absence of an external light source. Extrapolations on the Na3-X amplifier concept involving Group IIA metal - F, CI reactions are considered. Very near resonant energy transfers from selectively formed metastable states of SiO to receptor alkali atoms form sodium or potassium atom laser amplifiers, resulting in a gain condition at lambda = 569, 616, 819, and 581 mm.
