ABSTRACT:
An improvement in an electrical discharge laser. The improvement consists of modulating the input power to the laser; specifically, in the case of a gas laser for instance, either (1) the power to the electron gun which produces an electron beam used for preionization of the gas, or (2) the power to the main discharge electrodes of the laser. The parameters of the modulation, i.e. its frequency and depth, are matched to the vibration energy transfer characteristics of the molecules of the lasing medium, which in the preferred embodiment is a CO mixture.
