Gas laser pulses generation - uses specified gas fill with metallocene admixture exposed to UV light pulse

摘要

The gas laser has a gas mixture of carbon dioxide, nitrogen, and helium which is exposed to an electric discharge at each pulse. In order to attain a homogeneous discharge an admixture of a metallocene vapour is added to the gas mixture for its photo-preionising. The gas mixture, wetted with the vapour is exposed to an ultraviolet light pulse, at least before one discharge. Preferably ferrocene or nickelocene are used in powder form which is added to the gas stream for the laser. The powder may be deposited on a wall of a gas discharge tube through which the gas mixture flows.
