| Abstract | ||
| Design and manufacture of high reflectance He: Ne laser mirrors have been fulfilled. Dielectric materials such as zinc sulfide and Magnesium fluoride are used as high and low index materials to obtain of low losses laser mirrors. To obtain high reflectance, the sequences are arranged in stacks of quarter-wave of alternative high and low index. The two materials show a large difference in refractive index to obtain high reflectance value with the least number of layers. Any addition of layers does not effect the zone of high reflectance. | ||
