Gas laser systems

摘要

A gas laser system which provides sequence lines of emission in addition to the regular lines. The system includes a discharge cavity having a discharge tube and a hot gas absorber cell. The lasing gas and the gas in absorber are identical and may be either CO2, N2O or isotopes of this gas. The absorber cell is approximately 1/5 to 1/3 the length of the discharge cavity with the interior temperature of the absorber cell being greater than 200 DEG C. and the pressure within the cell being in the order of 20 torr.
