Investigation on Parallel Spark Array Pre-ionization TEA CO2 Laser

摘要

Operation of a TEA CO2 laser with parallel spark array pre-ionization is investigated. Low repetition rate pulsed laser has been made having integrated pre-ionization and peaking circuits. The effect of gas mixture, applied voltage and capacity of the main , peaking and preionization capacitors on output power of the laser are presented. Total efficency up to 7% was obtained and although the fraction of the He in gas mixture was only 58% stability of discharge was good (2 arc in 55 discharges).
