Abstract
Laser gain is reported on the 4p3d 3F - 4s3d 3D transitions of Ca at 643.907, 646.257, 647.166, and 649.378 nm following optical pumping of the 4s2 1S0 - 4s4p 3P1 intercombination transition at 657.278 nm. The effect is realized through large scale collisional redistribution of energy which rapidly leads to the excitation of higher states and eventual ionization of Ca atoms. Our calculations based on a simple rate equation model suggest that population inversions are a combined result of direct excitation of the upper lasing states through inelastic collisions, and three-body recombination.
