Development of laser mirrors of very high reflectivity using the cavity-attenuated phase-shift method
Abstract
A simple four-step procedure for obtaining mirrors of very high reflectivity is described. The success of the technique is based on the ability to measure the scattering and other losses of the substrates and dielectric coatings to ensure that the specifications are being met. These measurements are especially critical in the cleaning process. The cavity-attenuated phase shift method is well suited for performing these measurements, making it possible to obtain mirrors with reflectivities of 0.99975 + or - 0.00005.
