ABSTRACT:
A compact drive system drives an RF-excited gas laser to produce laser energy. The drive system is implemented on a ceramic circuit board having a high dielectric constant. The drive system includes an RF energy source that produces RF energy that is transmitted by a quarter-wave transmission line to the plasma tube of the laser. The transmission line is a microstrip transmission line having a conductive strip and a conductive ground plane bonded to opposite sides of the ceramic circuit board. Such a microstrip transmission line enables the entire drive system to be implemented on the ceramic circuit board. The drive system includes a feedback path to the input of the RF energy source transistor, which enables the drive system to be self-oscillating in that the frequency of the RF energy produced is maintained equal to the resonant frequency of the laser.
