Abstract
The present disclosure provides embodiments for optical cavity apparatuses and methods for assembling such apparatuses. For example, an optical cavity apparatus includes a body and two mirrors that are attached to the body and form an optical cavity having an optical path inside the body. Furthermore, the body has an opening that allows gas to be pumped out of the optical cavity; and includes a closing means attached to the opening that can be closed for maintaining, after pumping the gas out of the optical path, a negative pressure in the optical cavity.
Claims14
An optical cavity apparatus, comprising:
- a body comprising an opening;
- two mirrors that are attached to the body and form an optical resonator having an optical path inside the body, wherein
- the opening allows gas to be pumped out of the optical resonator;
- and
- a pinched-off pinch-off tube attached to the opening that seals the optical resonator from an atmosphere outside the body and maintains a vacuum in the optical resonator.
A method for assembling an optical cavity apparatus, comprising:
- providing a body;
- providing two mirrors;
- processing the body to have:
- a cavity that comprises an optical path to be formed by attaching the two mirrors at predetermined positions to the body, and
- an opening that allows gas to be pumped out of the cavity after the two mirrors are attached at the predetermined positions to the body;
- attaching the two mirrors at the predetermined positions to the body thereby making the cavity an optical resonator having the optical path inside the body;
- providing a pinch-off tube;
- and
- attaching the pinch-off tube to the opening;
- pumping air out of the optical resonator via the pinch-off tube;
- and
- pinching off the pinch-off tube, thereby sealing the optical resonator from an atmosphere outside the body and maintaining a vacuum in the optical resonator.
