Abstract
A laser having a gain medium which includes boron oxide (BO) is shown to have an increased optical power output and to achieve other benefits from the addition of carbon tetrafluoride (CF.sub.4) to the gain medium. CF.sub.4, when mixed with BO, induces a vibrational relaxation of a BO(A.sup.2 .pi.) population to a single vibrational level without a significant quenching of the BO(A.sup.2 .pi.) state. The rate of vibrational relaxation induced by the CF.sub.4 additive occurs in an interval of time which is less than that associated with the radiative decay and quenching of the BO(A.sup.2 .pi.) state.
