Abstract
Results are reported of an investigation of fundamental kinetic processes influencing discharge and laser properties typical of the 502‐nm HgBr(B→X)/HgBr2 dissociation laser. Specific attention is focused on conditions representative of electron‐beam‐controlled discharges. Experimental results and corresponding analysis and interpretation are presented for several laser mixtures, focusing particularly on the factors affecting discharge characteristics and HgBr(B) formation. A set of phenomenological electron‐HgBr2 cross sections inferred on the basis of analysis of experimental observations is presented, along with a discussion of the effect of electron‐electron collisions on medium properties at the level of fractional ionization typical of the HgBr(B)/HgBr2 laser.
