Dielectric High Reflective Coating

It is well know that dielectric coating can produce very high reflection (more than 99.8% at designed wavelength). This coating is generally used in a single wavelength laser cavity, where the lowest cavity loss at center wavelength is essential. Sinoceramics can provide such coatings with center wavelengths from 350nm to 2000nm according to customer’s requirement. When selecting a suitable dielectric high reflection coating, the damage threshold requirement must be considered.
