摘要

摘要实验发现，当用伽马-中子混合辐射核反应堆泵浦 Ar-Xe-CCl4 介质时，在 XeCl* 分子的 B-X- 和 C-A 转变（308，352 nm）处，核泵浦准分子激光器的有源介质增益下降。这种效应是由于准分子激光器活性介质中形成的次级电子在瞬时伽马辐射的影响下产生的淬火效应。这种效应随着伽马辐射通量密度的增加而明显增大，损耗系数可达 ~10-2-2 × 10-2 cm-1。

Generation and Quenching in the XeCl* Excimer Laser Pumped by Mixed Gamma-Neutron Radiation from a Nuclear Reactor

A decrease in the gain of the active medium of a nuclear-pumped excimer laser has been experimentally discovered at the B–X- and C–A-transitions of the XeCl* molecule (308, 352 nm), when the Ar‒Xe–CCl₄ medium is pumped with mixed gamma-neutron radiation nuclear reactor. The effect is due to the quenching effect of secondary electrons formed in the active medium of an excimer laser under the influence of instantaneous gamma radiation. The effect increases significantly with increasing gamma radiation flux density, and the loss coefficient can reach values of ~10^–2–2 × 10^–2 cm^–1.
