β¦ Synopsis
Characteristics of excimer laser-generated pulsed Na beams are studied by time-resolved emission spectroscopy and LIF techniques. Fast speed Rydberg state Na atoms, slow speed Na: and Na aioms are identified experimentally. Their formation mechanisms are attributed to the inverse bremsstrahlung and the photothermal processes. Rydberg state metal atoms with kinetic energies in the range of a few lo more than 100 eV can be generated by this laser vaporization technique.

We measured the HF Iaser energy output of a pulsed chemical laser as a function of pressure and mixing ratio for various mixtures of IF, and H, . A pulsed electron beam was used to initiate the chemicxI reaction. We found that the laser energy output peaks at approximately 100 torr for a wide we of
