Cathodes For Ion Gas Lasers


  • Despite the success of the solid state and semiconductor lasers, ion gas lasers are still widely used in a variety of industrial and scientific applications because of their superior characteristics in terms of coherence of the laser beam.
  • Since the beginning of the development of ion gas lasers, Spectra-Mat contributed to the success of the technology.
  • Since then Spectra-Mat has manufactured thousands of high quality and highly reliable cathodes.
  • Spectra-Mat Patent N° 3514661.
