Patent ID: 8098705

Claim:
A gas laser comprising: a pair of substantially mutually parallel and opposed electrodes, between which a volume is defined, said volume containing a gas in which said electrodes generate a discharge; at opposed ends of said electrodes, in said volume, mirrors to define a resonant cavity, wherein said electrodes form an integral part of two portions of a sealed housing, containing said gas and in which said mirrors and said electrodes are housed, each of said electrodes having a substantially elongated rectangular extension and each of said electrodes having a flat surface, said flat surfaces being mutually parallel and delimiting said volume containing the gas, said two housing portions being electrically insulated from each other by means of an insulating element arranged between said two housing portions, wherein a first of said housing portions has a first perimeter edge and a second of said housing portions has a second perimeter edge, said two perimeter edges being mutually coupled with interposition of said electrically insulating element.
