| Abstract | SummaryUsing a high pressure CO2-laser we have studied laser action in12CD3F stimulated by R-branch pumping. We used an arrangement with low-feedback mirrors as suitable for Raman laser action. However, no Raman laser action has been observed in12CD3F though similar experimental conditions were met as for12CH3F and13CH3F. The reason for the different behavior of the gases is not yet clear.Instead of Raman laser action we found 15 FIR resonant laser lines with 13 of them unknown up to now in the frequency range from 50 cm−1 to 68 cm−1. We reached FIR pulse energies up to 900 μJ, corresponding to a photon conversion efficiency of 12%. For our arrangement the optimum operation pressure varied from 40 torr at low J values (J=36) to 70 torr at high J values (J=49). |
