Search for the composition of the active medium of an HgF laser

An emission band corresponding to the B →X transition in the HgF molecule was recorded in the spectra of a plasma produced by a high-voltage pulse-periodic discharge in mercury difluoride and trifluoromethylmercury fluoride vapor. This indicated that it is advisable to use pumping methods based on a dissociative excitation mechanism in attempts to develop an HgF laser.
