Abstract:

A transversely RF excited gas laser with an internally folded resonator includes an elongated chamber of cross-sectional dimensions suitable for confining a laser gas discharge, a plurality of reflectors and a laser gas. The reflectors form a stable folded laser resonator cavity of a compact geometry in order to efficiently extract laser power from the laser resonator cavity. There are at least two of the reflectors and at least one of the plurality of reflectors is concave. The laser gas is disposed in the folded resonator cavity which reflect and guide light energy from the laser gas discharge within the elongated chamber. The transversely RF excited gas laser with an internally folded resonator also includes a pair of electrodes and a pair of cooling electrodes. The electrodes are transversely disposed on the elongated chamber and excite the laser gas. The cooling electrodes are transversely disposed on the elongated chamber and electrically coupled to ground.
