4Lasers variable reflectivity mirrors provide a circularly symmetric reflectance profile according to the super-Gaussian function with an order of 2. These mirrors are favorable in high-power unstable laser resonators for their wide filling of the active medium and weak diffraction on the hard-edge aperture. Therefore, super-Gaussian variable reflectivity mirrors contribute to better near- and far-field beam quality. It is worth mentioning that variable reflectivity mirrors can be designed to have various reflectance profiles, such as linear, parabolic, Gaussian.

In order to have better beam quality, i.e. in non-stable resonators, variable reflection mirrors - variable reflectivity 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. Standa offers variable reflectivity mirrors with dielectric coating, designed at wavelengths in a range from 266 to 2500 nm.
