Mirrors

A mirror comprising a multi-layer dielectric (MLD) reflective stack and a dielectric layer which acts as a half-wave spacer for a specific wavelength of light at a predetermined angle of incidence so as to enhance the absorption or transmission, or both, of s-polarized light relative to that of p-polarized thereby to enhance the reflection of p-polarized light relative to that of s-polarized light further comprising an off-tune MLD underlying said half-wave spacer.

A mirror comprising a multi-layer dielectric (MLD) reflective stack and a dielectric layer which acts as a half-wave spacer for a specific wavelength of light at a predetermined angle of incidence so as to enhance the absorption or transmission, or both, of s-polarized light relative to that of p-polarized thereby to enhance the reflection of p-polarized light relative to that of s-polarized light further comprising a magneto-optic layer.

A ring laser gyroscope comprising a mirror including a multi-layer dielectric (MLD) reflective stack and a dielectric layer which acts as a half-wave spacer for a specific wavelength of light at a predetermined angle of incidence so as to enhance the absorption or transmission, or both, of s-polarised light relative to that of p-polarised light thereby to enhance the reflection of p-polarised light relative to that of s-polarised light.

A mirror comprising a multi-layer dielectric (MLD) reflective stack and a half-wavelength dielectric layer of high refractive index overlying said MLD stack so as to enhance the absorption or transmission, or both, of s-polarized light relative to that of p-polarized light thereby to enhance the reflection of p-polarized light relative to that of s-polarized light.
