Study of fission-fragment excited xenon laser in He-Xe, Ar-Xe, and He-Ar-Xe mixtures

摘要

Data on energy and threshold characteristics of xenon laser in the He-Xe (2.65 μm), Ar-Xe (1.73 μm), and He-Ar-Xe (2.03 and 2.65 μm) mixtures have been measured as a function of xenon partial pressure and output mirror reflectivity. Investigations were carried out using LUNA-2M setup irradiated by neutron flux of VIR-2M pulse reactor with pulse duration of about 3 ms. Using the experimental data and Rigrod model, small-signal gains and saturation intensities were determined.
