Abstract
A diamond magneto-optical sensor includes: a diamond including a color center with an electronic spin, and a reflecting surface that reflects excitation light propagated through an optical system into the diamond, wherein the reflecting surface reflects light radiated from the color center excited by the excitation light and condenses the light in the direction of the optical system.
Claims3
A diamond magneto-optical sensor comprising:
- a diamond including a color center with an electronic spin;
- a small portion that allows excitation light propagated through an optical system to be emitted into the diamond, and
- a reflecting surface that reflects radiated light radiated from the color center excited by the excitation light incident from the small portion and condenses the radiated light in a direction of a light-receiving optical system that guides the light to a light-receiving element,
- wherein the reflecting surface has a larger area than the small portion and guides the light radiated from the same position in different directions, to the light-receiving optical system through a plurality of optical paths,
- wherein the excitation light is emitted to the diamond from an output part of the optical system, and
- wherein the reflecting surface condenses the radiated light at the output part of the optical system.
