Attention! You can customise this product to your needs.
In order to have better beam quality, i.e. in non-stable resonators, variable reflection mirrors can be used. High intensity of the laser beam requires use of components with a high damage threshold. Dielectric coatings are best suited to meet these requirements. Altechna offers variable reflectivity mirrors with dielectric coatings, designed for wavelengths in the range from 266 to 2500 nm.
