Background

Laser is another important invention of human beings after nuclear power, computers and semiconductors in 20 th century, and is called as "fastest knife", "best-line ruler" and "brightest light". The english name light amplification by modulated Emission of radiation means "amplified by Stimulated Emission of light". The english full name of the laser has fully expressed the main process of making the laser. The principle of laser light was discovered by the famous jewish physicist einstein as early as 1916.

The atoms are stimulated to emit light, hence the name "laser": when the electrons in the atoms absorb energy and then jump from a low energy level to a high energy level and then fall back from the high energy level to the low energy level, the released energy is released in the form of photons. The induced (excited) photon beam (laser) has highly uniform photon optical characteristics. Therefore, compared with a common light source, the laser has good monochromaticity and directivity and higher brightness.

The laser is widely applied, and comprises laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser weapons, laser records, laser correction of vision, laser cosmetology, laser scanning, laser mosquito killer, LIF nondestructive testing technology and the like. Laser systems can be divided into continuous wave lasers and pulsed lasers.

A cavity in which optical cavity (optical resonator cavity) light waves are reflected back and forth to provide optical energy feedback. The necessary components of a laser are usually made up of two flat or concave spherical mirrors perpendicular to the axis of the active medium.

The optical cavity has two roles, one to provide positive feedback and one to control the characteristics of the oscillating beam within the cavity.

According to the shapes of two reflectors forming a resonant cavity and their relative positions, the optical resonant cavity can be divided into: a parallel plane cavity, a flat concave cavity, a symmetrical concave cavity, a convex cavity, etc. If the focus of the concave mirror in the flat concave cavity is just on the plane mirror, the concave cavity is called a semi-confocal cavity; if the sphere center of the concave mirror is on the plane mirror, a semi-concentric cavity is formed. The curvature radiuses of the two reflecting spherical mirrors in the symmetrical concave cavity are the same. If the mirror foci are all located at the midpoint of the cavity, it is called a symmetric confocal cavity. If the spherical centers of the two spherical mirrors are at the center of the cavity, the two spherical mirrors are called concentric cavities.

Patent number CN204529301U discloses an optical micro-nano resonant cavity structure, the optical micro-nano resonant cavity structure includes two single-row particle chains having a total reflection function for working electromagnetic waves, the single-row particle chains are composed of a plurality of particles arranged at intervals, and the interval distance between the two single-row particle chains makes the resonant wavelength of the optical micro-nano resonant cavity structure be the wavelength of the working electromagnetic waves. According to the invention, the total reflection characteristic of a single-row particle chain to specific polarized light is utilized, and a novel high-quality factor optical micro-nano resonant cavity is obtained by optimizing the structure of the single-row particle chain and the distance between two single-row particle chains. The resonant cavity designed by utilizing the total reflection of the two single-row particle chains has the characteristics of low loss, high quality factor and small size, and has good application prospect in the field of integrated optics.

The optical micro-nano resonant cavity structure has the following disadvantages when in use: 1. when the optical micro-nano resonant cavity structure is used, the reflecting height of the total reflector cannot be rapidly adjusted, and further the reflecting effect is poor.

2. When the optical micro-nano resonant cavity structure is used, an output mirror in the device cannot be quickly replaced or maintained, so that the replacement efficiency of the output mirror is low.
