Observation of XeF (C ? A) laser action in liquid argon
Abstract:
Superradiant and laser emissions of the XeF (C ? A) transition were observed at 530 nm in liquid argon for the first time to our knowledge. The liquid samples were prepared from Ar/Xe/F(2) mixtures in a ratio of 1600:10:1 and pumped by a commercial excimer laser at 351 nm. Dramatic line narrowing of the initially broad (FWHM ~60 nm) C ? A fluorescence spectrum was induced at elevated pump powers. The XeF (C) state excimer number density was estimated to be in excess of 5.26 x 10(17) cm(-3).
