摘要: A new approach, based on a double-pulse-discharge technique, has been successfully performed on a LE CO2 laser. This technique consists of two consecutive discharges. First, the preionization discharge, which is higher in voltage and less energetic. Then, after some delay time, the main discharge follows. TEA laser can perform double-discharge effectively, but it requires auxiliary preionization-electrodes.Double-discharge technique has been only possible for multi-electrode lasers[1]. Now, the new technique developed by us has been demonstrated to be capable of solving the aboved-mentioned difficulty beneficially. The discharge circuit is mainly constructed by using capacitors and spark gaps, and is ready to apply to any two-terminal discharge tube. Comparosons between this device and the same discharge tube[4,5] usinng conventional excitation technique show that the laser energy and overall efficiency can be increased at least by a factor of 1.5, and the optimal E/P ratio was decreased. Furthermore, the improved discharge conditions also enable arcingfree operation with higher pressure than that of applying conventional discharge technique. Up to the present time, this is the only preionization technique for the LE CO2 laser.
