Title: Ulraviolet-resistant high-reflectivity multilayer dielectric mirror
Inventor: BARETSUTO II KOORU
IPC: H01S3/08
Filed: 1989-12-05
Abstract: PURPOSE: To obtain a multilayered dielectric mirror which does not respond to a gyro environment without requiring many layers by forming the mirror of a plurality of thin TiO2 film/SiO2 1/4-wavelength layer pairs formed on a substrate and a plurality of second HfO2 or ZrO2 dielectric thin film/SiO2 1/4-wavelength layer pairs respectively formed on the thin TiO2 film/SiO2 1/4-wavelength layer pairs. CONSTITUTION: Many thin TiO2 film/SiO2 1/4-wavelength layer pairs 10 are formed on a substrate 11. On the first thin TiO2 layer/SiO2 1/4-wavelength layer pair, a second HfO2 or ZrO2 dielectric thin film/SiO2 1/4-wavelength layer pair 12 is formed. Since the high-refractive-index material of the lower layer, such as TiO2 , etc., has a high refractive index, a high reflectivity level can be attained, but each thin TiO2 film/SiO2 1/4-wavelength pair has sensitivity to UV. In order to reduce the sensitivity of a multilayer dielectric mirror to UV, the mirror is constructed in the above-mentioned two-layer structure in which the TiO2 /SiO2 layer pairs are coated with the HfO2 /SiO2 or ZrO2 /SiO2 pairs so as to bury the UV-sensitive material in the stack. Therefore, the sensitivity of the mirror to UV is reduced, and the total number of the constituent layers can be reduced.
