Lasing on the D’ - A’ transition of BrF molecules (355 nm) excited by TEA discharge

Abstract

High-power lasing was obtained on the electronic D’-A’ transition of the BrF molecules using a transverse electric discharge as a method of pumping a high-pressure He-Br2-NF3 active medium (5 atm). The maximum laser energy was 13 mJ. With the laser pulse duration of 10±2 ns (FWHM), the peak power was more than 1 MW.
