Study on a Non-Chain Discharge-Pumped Pulse Deuterium Fluoride Lasers
The compact non-chain discharge-pumped pulse deuterium fluoride (DF) laser is studied, the discharge trigger circuit is introduced based on one-stage thyratron magnetic pulse with fast rise time. Discharging voltage of 39.5 kV and pulse rise time of 100 ns are achieved. With the condition of 190 J/L energy depositions, a uniform glow discharge is formed using compact Chang-electrode combined with ultraviolet (UV) spark pre-ionization, and the distance between the cathode and anode is 30 mm. With flat-flat cavity laser resonators, mixture gas of SF6and D2is investigated. By optimizing the gas ratio to 10:3, the laser pulse energy is up to 877 mJ. The electro-optic conversion efficiency is about 1.9% and the pulse width is 200 ns with the beam dimensions of 30 mm×9 mm.
