High power triple laser mirrors

Laser Components has developed a new coating method that enables the production of triple mirrors in a single coating run. Not only does this reduce production time, and thus the unit cost, but also yields a higher spectral performance than previous production techniques. This method allows for triple mirrors with custom wavelength combinations to suit any application.

When using frequency multiplying lasers, laser optics must be optimised for each of the wavelengths produced. Triple mirrors are used for this purpose, and a high degree of reflectivity at each of wavelength is required. Traditionally, mirror coatings for different wavelengths have been applied in two separate runs, resulting in costly and time-consuming triple mirror production.
