摘要：An electrically excited laser is disclosed wherein a laser gas is caused to flowalong a gas flow channel and through an excitation region thereof in which an electricdischarge is established between an anode and a cathode disposed substantially flushwith respective opposing walls of the gas flow channel, and wherein an electron beam isintroduced into the excitation region along a direction parallel to the discharge direction.A shield arrangement is provided immediately downstream from the laser excitationregion to confine the discharge to the region directly between the anode and thecathode. The shield arrangement includes a plurality of planar electrically insulating rackmembers disposed across the gas flow channel in respective spaced planes parallel toboth the direction of the discharge and the gas flow direction, and a plurality of planarshelf members carried by the rack members and oriented with their board surfacestransverse to the rack members. The shelf members are tightly fit within grooves in therack members and are held in place by the gas flow pressure without any bonding orcementing.
