Title: Simultaneous three primary color laser emissions from dye mixtures

Abstract

Simultaneous two- and three-band laser emissions were obtained in a process of mixing two and three kinds of dyes excited by a nitrogen laser. They were blue, green, and yellow in a coumarin 460 (C460)/disodium fluorescein (DF)/rhodamine 610 (R610) dye mixture, and blue, green, and red in a C460/DF/rhodamin 640 (R640) dye mixture. Strong energy transfers from DF to R610 and to R640 were shown. R610 and R640 laser emissions on mixing with DF were obtained at very low concentrations. They were 4{times}10{sup {minus}6} mol/l for R610 and 1{times}10{sup {minus}5} mol/l for R640, compared to the lasing threshold concentration of 1{times}10{sup {minus}4} and 2{times}10{sup {minus}4} mol/l of each dye alone. Also, the R610 radiation moved about 35 nm to a shorter wavelength at the reduced concentration.
