Abstract
When using CO as the absorbing and lasing species for vibration-vibration energy transfer and subsequent vibration-vibration pumping, CO can be made to dissociate and subsequently form C.sub.2 with isotope separation, or CO may be made to chemically react with N.sub.2 to produce CN with isotope separation.
Claims5
A method for initiating chemical reactions in a mixture of flowing gases by low pressure optical pumping including the steps of:
- supplying a mixture of gases, including at least one species capable of resonant absorption of pump radiation, to an absorption cell;
- flowing the mixture of gases through the absorption cell;
- and
- irradiating the mixture of gases in the absorption cell with radiation from a pump laser having a lasant species which produces radiation capable of resonant absorption by said at least one species whereby said at least one species in the absorption cell absorbs pump laser radiation in the lower vibrational states of said at least one species and by vibration-to-vibration pumping populates the upper vibrational states of said at least one species.
