Variable reflectivity mirrors «In Stock»

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.
