Abstract: In this paper, we report new optically pumped far-infrared (FIR) laser lines from the in-plane CD3-rocking and asymmetric CD3 deformation absorption vibrational bands of (CD3)-C-13 OD. A waveguide CO2 laser of wide tunability (290 MHz) was used as the pump source, and a Fabry-Perot open cavity as the FIR laser resonator. Optoacoustic absorption spectrum was used as a guide to search for new FIR laser lines, We could observe 14 new laser lines in the range 103-491 mu m. The lines were characterized according to wavelength, relative polarization, relative intensity, and optimum working pressure. The transferred lamb-dip technique was used to measure the frequency absorption transition for both new and previously reported laser lines.
