Abstract

It is known that in the case of molecular media, which show rich emission spectra, the optical resonator can select several lines, line by line, like in the co ₂ laser medium. Usually the lines appear in some "quasi-chaotic" order but their order can be predicted [1]. In our experiment it has been pointed out that co₂ laser lines can appear in the natural order of the co₂ emission spectrum. It was found that the longitudinal tuning of the co₂ laser could give a well-ordered laser signature - the WOLS effect. As we showed, also other sophisticated signatures are possible.
