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.
