ABSTRACT:
A laser device with a discharge tube forming a closed envelope with cylindrical end portions connected by an elongated constricted center portion and having external electrodes at the end portions, fed from a source of short pulses with a width measured in nanoseconds, capacity coupled to the discharge plasma. The discharge plasma may include metal vapor, a metal halide, including mercury halide, and internal electrodes may be included in the closed envelope but coupled to the external electrodes by capacity coupling so as to avoid any connections from electrodes passing through the glass or fused silica envelope.
