Abstract
A ballast resistor device for use in a gas laser system for stabilizing the operation of the gas laser includes a housing, a ballast resistor element and a filler material filled in the space between the housing and the resistor element is provided. In the preferred embodiment, the filler material is substantially high in dielectric breakdown strength as well as in thermal conductivity, so that the ballast resistor device of the present invention has a rigid structure providing a strong mechanical and electrical durability, not to mention an excellent heat dissipating characteristic thereby allowing to prevent the resistor element from being overheated.
