Abstract
An investigation of exciplex pumped alkali laser (XPAL) has been conducted. A 4-cm gain cell containing Cs as an active medium is pumped by a tunable Ti: sapphire pulse laser. Laser oscillation is observed in both five-level and four-level systems. Small signal gain and saturation intensity of the active medium is measured by both probe laser amplification and oscillation experiment with varied output coupling. A one-dimensional numerical simulation is developed and the result of calculations is compared with the experiments. The pulse shape and oscillation threshed agree reasonably while calculated optical-optical conversion efficiency is underestimated.
