Abstract
The efficiencies of laser isotope separation processes based on multiple photon absorption from infrared laser pulses are enhanced thermally by raising the temperature of the gas upon which the laser beam is incident, thereby increasing the absorption and the isotopically selective excitation which enables isotopes in the gas to be separated. This same enhancement is applicable to processes for laser purification of gases which involve multiple photon absorption from infrared laser pulses.
