Scalable overtone HF chemical laser
Patent
·
OSTI ID:6905229
A method of producing essentially coherent electromagnetic emissions with high efficiency from excited HF molecules at overtone frequencies is described comprising the steps of: thermally dissociating a molecular gas containing fluorine to produce F atoms; reacting the F atoms with a gas containing hydrogen to produce excited HF molecules; preferentially depleting ..delta..v=2 overtone vibrational transitions of the excited HF molecules to produce the electromagnetic emissions at overtone frequencies such that the electromagnetic emissions from the ..delta..v=2 overtone vibrational transitions have an output power which is a significant percentage of the output power obtainable from ..delta..v=1 fundamental vibrational transitions of excited HF molecules so that the electromagnetic emissions produced by the ..delta..v=2 overtone vibrational transitions can be efficiently scaled to high output powers.
