Resumen
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 13CD3OD. 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 μm. 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. 35 11 1613 1615 Moruzzi, G., Moraes, J.C.S., Strumia, F., Far-infrared laser lines and assignments of CH3OH - A review (1992) Int.
