Transverse electrically excited the gas discharge laser for the generation of light pulses having a high pulse repetition frequency and a process for preparing

摘要

The gas discharge laser with a discharge tube, main - and the auxiliary electrodes, resonator mirrors and an electric excitation circuit can be in the light pulses to generate subnanosecond. They have a broad range of applications, for example, as a stimulation - or ionization light source in the case of different spectroscopy method and in conjunction with the uv - microscope. Known the gas discharge laser have various seals in the region of the discharge tube and are not be re-adjusted in the final assembled state. In the case of the invention, maintenance-free the gas discharge laser (gl) having a capability in the range of several 100 million are light pulses for fine adjustment the main electrodes (he1, he2) in the deformable support pans (tw) and the resonator mirror (rs) in the deformable support rings (tr) is supported, which by a hard solder (hl) is bonded to partial metal coatings (mb) on the discharge tube (it) are connected. All of the ultra high vacuum components are suitable for the complete removal of water via the second water limit (355°C.) bakeable. A preferred process for the production provides a hard soldering of above 900°C of the components with partial metal coatings (mb) on the discharge tube (it), a welding of the resonator mirrors (rs), a heating via the second water limit and a subsequent fine adjustment before.
