US 11,536,881 B2 · Conical mirror concentrator for a laser-cooled cold atom source

Abstract

A conical mirror concentrator is disclosed which is configured for use as a laser-cooled cooled atom source. According to embodiments, the conical mirror concentrator may comprise a body; a reflective inner conical surface formed on the body tapering from a large diameter at a first side of body inward to a smaller dimeter in an interior space of the body, wherein the inner conical surface focuses light to an axis within the interior space of the body; a hole extending from the interior space of the body near a pinnacle of the inner conical surface to a second, opposite side of body; and a structure configured to mount the concentrator to an ultra-high vacuum chamber, such as a CF (or Conflat) flange or an anodicly bonded glass plate.

Dependent claims

A conical mirror concentrator for a laser-cooled cold atom beam source comprising:

a body;
a reflective inner conical surface formed on the body tapering from a large diameter at a first side of the body inward to a smaller diameter in an interior space of the body, wherein the inner conical surface focuses light to an axis within the interior space of the body;
a hole extending from the interior space of the body near a pinnacle of the inner conical surface to a second, opposite side of body;
and
means for mounting the concentrator to a vacuum chamber and providing a vacuum seal therebetween comprising:
(i) a flange connected to the body, the flange being configured to readily deform around its circumference in conjunction with CF flange hardware to form the vacuum seal, or (ii) a glass plate anodicly bonded to the body.
