Diode Pumped Alkali Lasers DPALs are a new type of laser that uses alkali metal vapor as a gain medium and a buffer gas to control the line shape and kinetics. While these systems were first demonstrated in 2003 48 they have just recently been scaled to the kilowatt power levels in 2012 18. To achieve these powers, the design of the gain cell relied on a set of incomplete line shape and kinetic data. The current focus areas of DPAL research are the continued power scaling of the systems and basic science research into the rates involved within the system. The purpose of this research is to determine the physical parameters of various alkali noble gas interactions with a high degree of accuracy.
