Abstract
The turn-on delay of a gas laser is significantly reduced by creating a region of higher electric field intensity between the plasma discharge-confining region of the laser and the laser anode. This is accomplished by creating one or more regions of higher conductivity along the surfaces of the laser tube structure. In one embodiment, a conductive strip is placed upon the surface of the capillary tube containing the plasma discharge. In other embodiments, a second electrode for concentrating the electric field in the preferred region of the tube is included.
