Abstract

A compact and efficient multi-joule TEA CO₂ laser using the modified overshoot mode (MOM) magnetic-spiker sustainer (MSS) excitation technique is described, giving an enhanced laser performance at a significantly reduced spiker switching energy (typically ~5% of total input energy) necessary for producing a stable discharge. A laser output energy of 7.1J was obtained with an overall efficiency of ~13.5%. The implementation of this technique in a dual module 10J TEA CO₂ laser is also successfully obtained, demonstrating the scalability of this technology to high pulse energy (=10J) systems.
