Two and three photon ionization of Xe has been studied using excimer lasers. Employing a microwave bridge to determine the temporal behavior of the absolute photoelectron density, the cross‐section for two photon ionization of Xe at 193 nm has been measured to be (4±1)⋅10−32 cm4−W−1. An order of magnitude improvement in the peak electron density is realized by ionizing Xe with two XeF (351.1 nm) and one ArF (193.3 nm) photons. This process is resonantly enhanced by the 6p[1/2]0 level of Xe. The strong, selective pumping of this state has resulted in the observation of stimulated emission on the Xe {6p[1/2]0→6s[3/2]11} transition at 828.0 nm−the first optically pumped rare gas laser. |
