Abstract
The author reports that TEA-CO2 with an intra-cavity etalon is a useful pumping source which can deliver widely tunable beam (tunable range ∼1 GHz) with accurate oscillation frequencies and with high power compared to a tunable wave guide laser.
The source is applied to the excitations of CH3OH and the FIR emissions from it are well assigned for there absorption transitions and FIR emissions. This proves that the source display not only usefulness for development of new FIR emissions but also for molecular spectroscopy.
