TEA CARBON DIOXIDE GAS LASER DEVICE

摘要

A sealed-off CO2 TEA laser employs a corona discharge preionization technique and improved mechanical construction to improve vibration resistance and shelf life and to decrease sensitivity to the form of the electrical input. Extra-cavity preionizing electrode 310 is connected to cathode 301 by low inductance lead and is arranged relative to radiused edge 312 of anode electrode 302 to generate high field (>18 Kv/cm) in a region of the discharge space 320. The cavity housing is of four pieces all of the same material sealed together, e.g. by epoxy or glass frit bonding.
