Abstract :

In this research, a theoretical study to design high reflection mirrors which used as an output coupler for cw laser resonator have been established the (open filter) to study the multi–layers coating on (BK7) substrate From the results, the (maximum reflectivity was 98%) for mirror with (five layers) form (InSb+InAs). While the reflectivity become (90%) for mirror number of (GaAs+InSb) with the same number of layers. By use the MATLAB program, the reflectivity against the number of coating layers have been and studied. Finally we can get the maximum reflectivity when the optical thickness of coating layers quarter wave length and at this value the change in reflectivity become less.
