Abstract

For nearly 45 years, the optically pumped molecular laser has been the most prolific source of coherent far-infrared radiation. This type of laser system has generated over 5,000 discrete laser frequencies from about 0.025 to 3.030 mm. At Central Washington University, our optically pumped molecular laser system is a two laser system consisting of a carbon dioxide (CO2) pump laser that is used to excite the medium housed in the second, far-infrared laser cavity. For this investigation the media used to generate far-infrared laser emissions were the 13CD3OH and 13CD3OD methanol isotopologues, along with CD3CN, and 13CD3I. Between these four media 125 far-infrared laser emissions were generated, with 34 of these emissions being observed for the first time. The far-infrared laser emissions discovered during our investigation ranged in wavelength from 55.0 to 873.2 µm. This presentation will discuss the unique properties and operating characteristics of this specific far-infrared laser system, along with operational procedures utilized when searching for new laser emissions.
