Abstract

We have developed the resonance system which is able to operate a TE-CO2 discharge tube in two color emission source. The two color source is excellent in pumping efficiency, spacial overlap and time synchronization of the two emission CO2 lines.

We indicate that the competitive operation of the two emissions is well explained by a simple model.

When a TE-CO2 laser operates at the total pressure of below half atmospheric pressure, we make clear in this work that the operation of a TE-CO2 laser forms “depression” like hole burning, with regards to the J of the upper laser level by J-J collisional relaxation during the laser emission.

As an example of the two-photon source, two-photon pumping of NH3 and FIR emissions are given in this paper.
