Abstract

The probabilities of the two-photon ionization of cesium atoms by ruby laser light from 6p1⁄2, 6p3⁄2, 5d3⁄2 and 5d5⁄2 excited states were calculated. The densities of the excited atoms in the cesium discharge tube were estimated from the measured density and temperature of electrons. The calculated increases of the electron density show good agreement with the experimental results.
