The arrangement and operating principle of a setup for studying the main parameters of a beam of thallium atoms using the laser resonance atomic photoionization technique and the experimental results obtained are presented. The measured characteristics are the evaporation time, the atomic beam intensity, the evaporation rate, the saturated vapor pressure, and the heat of thallium evaporation.

Coherent radiation at the 1.28-\ensuremath{\mu}m electric-dipole-forbidden $6^{2}P_{\frac{3}{2}}\ensuremath{-}6^{2}P_{\frac{1}{2}}$ transition in thallium vapor has been produced by the simultaneous application of a magnetic field and two collinear, overlapping laser beams nearly resonant with the $6^{2}P_{\frac{1}{2}}\ensuremath{-}7^{2}S_{\frac{1}{2}}$ and $6^{2}P_{\frac{3}{2}}\ensuremath{-}7^{2}S_{\frac{1}{2}}$ transitions, respectively. The effect of the magnetic field is to mix hyperfine levels---atomic polarization effects are negligible. The optical difference-frequency power generated at low magnetic field varies as the square of the magnetic-field component normal to the laser-beam propagation direction.
