Theoretical simulation of a pulsed HF/DF optical resonance transfer laser
Abstract
The theoretical performance of a pulsed HF/DF optical resonance transfer laser (ORTL) is presented. The key reaction of HF/DF is the HF-DF V-V energy transfer reaction, but its rate constant has not been accurately determined so far. Therefore, in order to precisely predict the CW HF/DF ORTL experiment, the rate constant of the HF-DF V-V energy transfer reaction is determined to be dependent on V squared. The relationship between gas concentration (HF, DF, and He) and pumping condition (pumping intensity and pulse width) is determined to maximize the DF small-signal gain. As a result, it is found that the pumping HF laser lines of 2.7-3.0 microns are shifted to the ORTL lines of 3.9-4.3 microns at a low total pulse efficiency of about 0.1 percent.
