Future Possibilities, the Bromine and Chlorine Atom Lasers

Future Possibilities, the Bromine and Chlorine Atom Lasers 

Although a population inversion for the two states of the bromine atom has been observed following the vacuum ultraviolet photolysis of CF3Br,76 it has not yet proved possible to meet the threshold conditions for stimulated emission. The work reported in Ref. 76 showed that the intensity of the 

It has now been shown that a population inversion is not achieved between the aPi/2 and 2P% states of the chlorine atom in the vacuum ultraviolet flash photolysis of CF3C1,29 and thus the construction of a chlorine atom photodissociation laser appears remote at present.
