Multihyphen;Joule pulses from a sequence band transversely excited atmospheric CO2laser

摘要

We have used an inhyphen;cavity hot CO2cell to convert a conventional transversely excited atmospheric (TEA) CO2laser to operation on the 00thinsp;deg;2 sequence transitions. Careful cavity design enables us to attain efficient energy extraction. Output energies of 6 J per pulse have been obtained from a nonselective cavity, while a gratinghyphen;tuned cavity produces numerous sequence lines having output energies in excess of 2 J per pulse.
