Drive system for RF-excited gas lasers

Image Number 3 for United States Patent #5008894.

A system for improved drive and matching between an RF power source and a plasma tube in a laser system. The system uses standard 50 or 75 ohm quarter wave transmission lines as the sole interconnect and matching elements between discharge electrodes and drive transistors. The drive transistos may be operated in deep saturation or as switches providing near square wave output to approach the 100 percent theoretical electrical efficiency of switching power supplies. The system features better initial breakdown, bettwer discharge uniformity and power stability under narrow drive pulse conditions, lower matching electrical losses, and extreme simplicity and low cost.
