Discovery of Optically Pumped Far-infrared Laser Emissions from Formic Acid and its Isotopologues
Department or Administrative Unit
An optically pumped molecular laser system with a transverse excitation scheme has been used to generate far-infrared radiation. Over 100 laser emissions with wavelengths up to 1.03 mm have been detected with this system using formic acid and several of its isotopologues. This includes ten new laser lines which are reported with their operating pressure, power, polarization with respect to the CO2 pump laser, and wavelength measured to an uncertainty of ± 0.5 μm.
