Abstract

Multi-kolowatt pulses with limited wavelength tunability have been produced in several bands between 186 and 817 μm by pumping v3 P-branch transitions in12CH3F and12CD3F with the 10.6 μm band of a ten-atmosphere CO2 laser. The FIR emissions are all restricted to the immediate neighborhood of the resonances associated with successive J-numbers, but there is some evidence that additional off-resonant emission could be produced with stronger pumping. The optimum operating pressure for the various molecule/J-number combinations range from 7 to 75 torr and increase rapidly with increasing J-number.
