Abstract
A laser excitation lamp has a discharge tube and a hot cathode in the shape of a pin. The gas space is reduced in the region of the pin cathode. A method is also provided for production of the lamp, in which the gas space or the free cross section around the cathode is reduced by another processing step. The laser excitation lamp may be used as a pumping light source for lasing media.
