Observation of a large number of new laser lines from /sup 12/CD/sub 3/F gas optically pumped with a continuously tunable high-pressure pulsed CO/sub 2/ laser

An observation is reported of a large number of new laser lines from /sup 12/CD/sub 3/F gas optically pumped with a continuously tunable high-pressure pulsed CO/sub 2/ laser. Making use of the coincidence of the 10 mu m P and R branches of CO/sub 2/ with the v/sub 3/ and v/sub 6/ vibrational-rotational absorption bands of /sup 12/CD/sub 3/F, 180 laser lines were found in the wavenumber range between 8 and 55 cm/sup -1/, all of them yet unknown; these lines are studied for characteristic properties of laser action. All laser lines are assigned as pure rotational transitions in the vibrational excited or ground states.<
