Abstract
An asymmetric RF excited gas laser includes an elongated chamber, a first reflector and a second reflector, a first supporting mechanism, a ribbon of a metal conductor and a impedance-matching circuit. The elongated chamber is of cross-sectional dimensions suitable for confining a laser gas discharge and is formed from a dielectric material. A laser gas is disposed in the elongated chamber. The first and second reflector reflect and guide light energy from the laser gas discharge within the elongated chamber so that the light energy is optically independent of the internal walls of the elongated chamber as the light energy travels longitudinally the length of the elongated chamber. The first supporting mechanism supports the elongated chamber and forms negative electrode. The first supporting mechanism has cooling tubes and is electrically coupled to ground. The ribbon of the metal conductor forms a positive electrode which is disposed along the elongated chamber. An RF energy generator applies a voltage of alternating polarity to the positive electrode at a frequency ranging from 10 Mhz to about 3 Ghz in order to establish a laser gas discharge in the laser gas. An impedance-matching circuit matches the impedance of the elongated chamber and the positive electrode to the impedance of the RF energy generator.
