Method for generating laser pulses by means of a gas laser and apparatus for carrying out the method

摘要

Laser pulses are generated by means of a gas laser in which a gas mixture containing carbon dioxide, nitrogen and helium is at every pulse exposed to an electrical discharge. To achieve a homogeneous discharge, the vapor of a metallocene is added to the gas mixture which prior to at least a first discharge is irradiated with a pulse of ultra-violet light.
