Abstract
Absorption resonances in the ν2 band of D2O in near coincidence with CO2 laser lines are reported and assigned. Optical pumping induces strong laser emission at new submillimeter wavelengths, confirming the assignments. Acousto−optic modulation is used to tune the R (22) line of the CO2 laser into coincidence with the 000,533−010,422 D2O transition. Its center frequency is 1079.8628 cm−1; the linewidth (HWHM) due to collisional broadening is 13 MHz/Torr. D2S and HDS transitions in near coincidence with CO2 laser lines are also reported.Keywords
