Investigation of Gain and Absorption Processes in the Cadmium-Mercury Excimer.
Abstract
The CdHg excimer has received attention as a possible efficient visible laser medium. In the experiments described here, a pulsed, tunable laser was used to excite the Cd atomic state which forms CdHg excimers in three body collisions with Hg and Ar. Gain and absorption measurements were performed by using an argon-ion laser to probe several wavelengths within the 470 nm excimer emission band. Net absorption was observed at all wavelengths investigated. Acoustic and thermal disturbances which might mimic absorption have been carefully considered and it is determined that these are not important. We conclude that the CdHg excimer exhibits net absorption within its 470 nm emission band. These results cast considerable doubt on the possibility of efficient laser action in CdHg. (Author)
