Optics Balzers produces individually adaptable, application-specific laser cavity mirrors. A perfectly controlled coating optimizes the precise spectral parameters of the laser mirrors. The optimization of the spectral attributes allows the targeted influencing of the laser power yield.
With their spectral stability, gas lasers remain an indispensable signal source, especially in the fields of measurement technology and microscopy. However, the performance parameters are decisive in the optimization and adaptation of the lasers for the relevant applications.
The know-how of Optics Balzers, both in the polishing of the required substrates and in relation to the special coating technology, allows the performance parameters to be tailored precisely to each application. The reflection of the HR cavity mirrors can be guaranteed up to R>99.99%. The cavities´ OC mirrors have a transmission tolerance of +/- 0.05%. They are manufactured both as flat substrates and as substrates with a defined radius. Currently, a range of cavity mirrors of various radii is available, with diameters measuring from Ø6mm to Ø7.75mm.
All substrates for the cavity mirrors are made by an in-house polishing process. A P4 grade is standard for all substrates. On average, the residual roughness of substrates after the polishing process is RMS <0.3nm, and for assorted applications, substrates with an RMS value of <0.2nm are selected.
Our capacity for the precise process control of our coating technology along with the exceptional quality of our polishing process have been decisive factors in the success of the technological development of this Optics Balzers product line.
