Liquid or gas stimulated Brillouin scattering generation container

Abstract

The invention provides a liquid or gas stimulated Brillouin scattering generation container, which is characterized by comprising a semicircular guide rail, a spherical container and a laser emitting device, wherein the spherical container is used for containing a stimulated Brillouin scattering medium; the semicircular guide rail is more than the spherical container in diameter; the circle center of the semicircular guide rail and the sphere center of the spherical container are concentrically arranged; the laser emitting device is arranged on the semicircular guide rail in a sliding manner; when the laser emitting device slides on the semicircular guide rail, laser beams emitted by the laser emitting device pass through the semicircular circle center all the time; one laser beam emitted by the laser emitting device is used as one of the laser beams participating in stimulated Brillouin scattering; and the other laser beam participating in the stimulated Brillouin scattering is incident from the tail end of the semicircular guide rail and passes through the sphere center of the spherical container.

Problems solved by technology

[0002] The stimulated Brillouin scattering devices in the prior art are generally divided into two types, one is that the signal light and the pump light are in the same optical path, and the other is that the signal light and the pump light have a cross angle. Stimulated Brillouin scattering has different containers for containing corresponding liquids or gases. For stimulated Brillouin scattering with the same optical path, the corresponding containers are generally transparent cylinders or regular rectangles or squares , when performing stimulated Brillouin scattering experiments, it is only necessary to sequentially inject the laser for generating signal light and the laser for amplification in the same optical path, and there is stimulated Brillouin scattering with an included angle between signal light and pump light For example, Harbin Institute of Technology invented some corresponding containers, but there is a defect in these containers, because in order to minimize the light reflection loss, it is necessary to keep the incident angle at 90 degrees, which determines that for a specific medium tank Generally speaking, the angle between the two laser beams is fixed, because the two incident surfaces of the container itself for the incident two laser beams are fixed, so such a container can only complete the experimental process with a fixed angle, if During the experiment, it is basically impossible to change the angle between the two laser beams, but in many cases we need to change the angle between the two laser beams. A special case of the corner case, that is, the included angle is zero degrees. For the above two cases, it is necessary to prepare two kinds of containers, not to mention the high cost, and it will take up a lot of space in storage and use. For limited For test benches, it is often necessary to save as much space as possible
