Abstract:

The first observation of resonantly-enhanced Stark-induced two-photon mixing in a gas was previously reported on this program. Parametric single sideband generation in N14H2D at the difference frequency of 10.6 micrometers and 4 GHz microwave radiation was described. During this reporting period, exact confirmation of the theoretical prediction of conversion efficiency versus gas pressure was established by new precision measurements of the N14H2D absorption linewidth versus pressure. Two new parametric converter systems that promise increased parametric gain and conversion efficiency several times to two orders of magnitude have been identified. These are 1 the C12O216 P26 laser line and 2.15 GHz microwave radiation resonating with the Stark tuned vibrational-rotational transitions of N15H2D and 2 the isotopic C13 O216 R18 laser line and 26.378 GHz microwave radiation resonating with N14 H3. The basis for the increased gain is described.
