Abstract

In recent experiments the feasibility of using high pressure transversely excited (TE) discharge tubes for operation of pulsed Sr⁺ and Ca⁺ recombination lasers has been demonstrated.^1-3 Maximum specific energy densities on the 430.5-nm transition of Sr⁺ and on the 373.7-nm transition of Ca⁺ of ~50 μJ/cm³ (Ref. 2) and 30 μJ/cm³ (Ref. 3), respectively, have been achieved from an active volume of 30 cm³.
