Problems solved by technology

[0003] The present invention is proposed in response to the above problems, and provides a stimulated Brillouin scattering container and a method for using the container to perform stimulated Brillouin scattering. Using the stimulated Brillouin scattering container of the present invention, by balancing the cross The number of times or the crossing angle and the length of the container can solve the problem that the intensity of stimulated Brillouin scattering light cannot be enhanced, so that significantly enhanced stimulated Brillouin scattering light can be obtained

Embodiment Construction

[0011] The stimulated Brillouin scattering container of the present invention will be described in detail below with reference to the accompanying drawings. attached figure 2 It shows the stimulated Brillouin scattering container of the present invention, the container has at least two grooves in the length direction, the grooves are symmetrically distributed in the axial direction of the length direction, and in figure 2 In the given embodiment, the number of grooves is 2. The cross-section of the container can be a known shape, such as rectangular, circular, etc.

[0012] Wherein the stimulated Brillouin scattering container needs to satisfy the following relationship: when the angle between the two beams of light incident on the stimulated Brillouin scattering container is required to be 6, the two beams of light on the incident surface of the container The intersection points between the place and the surface of the container are respectively a and b, and the length be...

Abstract

Provided is a stimulated Brillouin scattering container with grooves. At least two grooves are formed in the container in the length direction, and the grooves are symmetric in the axial direction of the length direction. When it is required that the included angle between two light beams incident to the stimulated Brillouin scattering container is delta, the intersection points of the incident plane of the two light beams on the container and the surface of the container are a and b respectively, and the length between a and b is L1, the length of the portion, in front of the first groove, of the container is L2 and should meet the formula in the specification, H is the height or diameter of the first groove, and h is the height or diameter of the second groove. According to the container structure, enhanced stimulated Brillouin scattering signals can be generated.

Description

technical field [0001] The invention relates to a stimulated Brillouin scattering container and a scattering method using the container, belonging to the field of optical technology. Background technique [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 have the same optical path, and the other is that the signal light and the pump light have crossing angles, each of which has advantages and disadvantages, and the same optical path The need to integrate the two beams of light that participate in stimulated scattering into exactly the same path generally adopts two methods, one is to use a half-mirror, and the other is to use a polarizing beam splitter, but in either case The prominent problem brought about is the loss of more light energy. For the case where there is a cross angle, it is not necessary to use a half mirror or a polarizing beam splitter, which will not ca...
