Problems solved by technology

In order to meet these requirements, scientists have proposed a variety of transportable ultra-stable optical cavity designs. These designs can meet the handling requirements to a certain extent, but there is still a large extrusion force on the optical cavity during installation, resulting in too strong coupling with the outside, or Unable to withstand large vibration acceleration and shock, not suitable for vehicle, airborne, rocket launch and other scenarios

Abstract

The invention discloses a super-stable optical cavity comprising an optical cavity. The cavity is provided with a light through hole, a first protrusion, a second protrusion and a third protrusion. The super-stable optical cavity also comprises a first cavity mirror and the second cavity mirror and further comprises an adapter ring. The super-stable cavity is enabled to have low vibration sensitivity and maintain a stable mechanical structure so as to realize that the super-stable laser can withstand high vibration acceleration and is suitable for application in the non-laboratory environment.

Description

technical field [0001] The invention belongs to the field of optical experiment equipment, and in particular relates to an ultra-stable optical cavity. It is suitable for ultra-stable lasers, optical clock systems and precision measurement physics experiments. Background technique [0002] The ultrastable optical cavity as the frequency locking reference of the laser is a necessary device to generate ultrastable laser. It is mainly used in clock lasers of optical clocks and precision measurement physics experiments. In order to improve the frequency stability of the ultrastable laser in the experiment, it is necessary to require the ultrastable optical cavity to have very low vibration sensitivity. In order to ensure low vibration sensitivity, the traditional ultra-stable optical cavity is placed on several support points. The optical cavity cannot be moved and can only be used in the laboratory. [0003] With the maturity of ultra-stable laser technology, more and more w...
