The buildup and decay of the HgBr (FORMULA PRESENTED) species during a pulsed discharge in Ne, N2, and HgBr2 vapor and in its afterglow have been examined by monitoring (FORMULA PRESENTED) absorption by the discharge at 351 nm. Also, the UV-to-green conversion efficiency for the 350-nm pumped HgBr laser is shown to be sensitive to the 502-nm fluence circulating in the cavity when the XeF laser pump pulse arrives. The maximum observed efficiency (tj) of 22% is obtained for intracavity intensities of 1 to 2 MW/cm2, but η falls to ˜10% for I≃1 kW/cm2.
