Abstract:

The major effort was to perform definitive gain measurements on discharge-excited T1-Hg laser mixtures and to demonstrate T1Hg laser output at 459 micrometers if the gain measurement indicated that laser tests were warranted. Gain and absorption measurements of the discharge containing high densities of mercury 3 x 10 to the 19th power cm -3 and thallium 6 x 10 to the 16th power cm -3 were undertaken. No transient gain was observed within the T1Hg excimer band at 459 nm on the contrary, a strong absorption from Hg2 molecules in this region was detected. Author
