Observation of tunable far-infrared emission from optically pumped D2O with a 17-GHz tuning range.

ABSTRACT

We report the observation of tunable far-infrared emission from D(2)O with a 17-GHz tuning range. Using a tunable high-pressure CO(2) laser for optical pumping, we have studied laser emission from D(2)O and achieved tunable laser emission from 91.23 to 91.81 cm(-1) with a maximum detuning of 13 GHz from resonance. We have also studied the temporal behavior of the far-infrared laser emission.
