Abstract

Abstract

The design and performance of a non-chain transverse excited HF laser with ultraviolet spark is described. It has high energy implantation and great energy output, and takes a high power excitation system with thyratron combined magnetic pulse compression switch. The laser pulse energy was studied in different gas pressure and fractions of the media SF6 and H2. The maximal output energy 1.3 J was achieved under the condition of 88 kPa gas pressure with 10% H2 and 90% SF6. Laser electro-optical conversion efficiency 5.3% were obtained.
