Description
Technical Field
The invention relates to stimulated scattering, in particular to a device for improving the light intensity of stimulated Brillouin or stimulated Raman scattering, and belongs to the technical field of photoelectrons.
Background
Stimulated brillouin and stimulated raman scattering belong to scattering phenomena which are very important in nonlinear scattering, and many researches on stimulated brillouin and stimulated raman scattering in the prior art are carried out, wherein the stimulated brillouin and stimulated raman scattering can be generated and observed only by means of specific device and optical path design, the stimulated brillouin and stimulated raman scattering devices in the prior art are generally divided into two types on the design of optical paths, one type is that signal light and excitation light are in the same optical path, and the other type is that the excitation light and the pumping light have a cross angle, aiming at the two types of stimulated brillouin and stimulated raman scattering, for the first case, if the stimulated brillouin and the stimulated raman scattering are carried out in a liquid or gas medium, a container specially used for placing the stimulated brillouin and the stimulated raman scattering medium is needed, and the optical path design is carried out outside, the signal light and the exciting light are propagated in the medium in the same optical path, or only the exciting light is driven into the medium, the spontaneous brillouin scattering light is used as the signal light, for the optical fiber medium, the transmission of the light in the optical fiber is strictly limited in the optical fiber, so the optical path is necessarily in the same optical path, for the stimulated brillouin and the stimulated raman scattering in the same optical path, the corresponding container is generally transparent cylindrical or regular rectangle or square, only the laser for generating the signal light and the laser for amplification need to be sequentially incident in the same optical path when the stimulated brillouin and the stimulated raman scattering experiments are carried out, for the stimulated brillouin and the stimulated raman scattering in which the signal light and the exciting light have included angles, the corresponding container needs to be specially designed, for example, in order to minimize the light reflection loss, the intersection angle of the signal light and the exciting light needs to be kept at 90 degrees, however, in any case, the excitation light passes through the stimulated brillouin and stimulated raman scattering medium once, and in fact, when the excitation light passes through the medium once, the part of the energy of the excitation light converted into the signal light is only a small part, and most of the excitation light is wasted after passing through, so that the signal light of the stimulated brillouin cannot be greatly enhanced, and a great waste of energy is also caused.
The invention is provided aiming at the problems, and aims to solve the problems that the stimulated Brillouin and stimulated Raman scattering in the prior art are low in light intensity and serious in excitation light waste.
