Scalable overtone HF chemical laser

摘要

A chemically driven HF overtone laser operates from either thermal or electrical dissociation of a molecular gas containing fluorine. Significant output powers are produced from &Dgr;v=2 vibrational transitions. Free F atoms produced by both thermal and electrical dissociation techniques are reacted with a molecular gas containing hydrogen to produce excited HF molecules. Overtone transitions, i.e., . DELTA.v=2 transitions are preferentially depleted by both optical enhancement and preinjection techniques to produce overtone laser transitions.
