Description
Technical field
The present invention relates to stimulated Brillouin scattering, relate in particular to a kind of container that occurs for liquid or gas stimulated Brillouin scattering, belong to the photoelectron technology field.
Background technology
the stimulated Brillouin scattering device of prior art generally is divided into two kinds, a kind of is flashlight and pump light same light path, another is that flashlight and pump light exist intersecting angle, stimulated Brillouin scattering for these two kinds of forms, has respectively the different containers that is used for accommodating respective liquid or gas, stimulated Brillouin scattering for same light path, cell therefor is generally rectangle or the square of transparent cylindrical shape or rule, only need to produce the laser of flashlight and get final product for the laser that amplifies in the incident of same light path order when carrying out the stimulated Brillouin scattering experiment, there is the stimulated Brillouin scattering of angle for flashlight and pump light, some cell therefors have been invented by Harbin Institute of Technology, but these containers all exist a defective, in order to realize catoptrical minimizing, needing to keep the incident angle of laser beam is 90 degree, so for certain specific medium pool, angle between two bundle laser beam is fixed, because being used for two planes of incidence of incident two bundle laser beam, fixes by container itself, so such container can only be the experimentation of completing fixed angle, if want to change the angle between two bundle laser books in experimentation, basically can not realize, but in a lot of situations, we need to change the angle between two bundle laser beam, and from essence, the situation of same light path just has a kind of special case of angle situation, also namely wherein angle is zero degree, for above-mentioned situation, just need to prepare the container of different angles, the cost height is not said, and can take very large space in storage and use, and for limited testing table, often need to save space as much as possible.
Summary of the invention
The present invention puts forward for above-mentioned defective, the container that a kind of stimulated Brillouin scattering for liquid or gas occurs has been proposed, use this container, can one of address the above problem at least, it can change arbitrarily the angle between two bundle laser beam, this angle almost can change to 90 degree from 0 degree, and in the process of Angulation changes, the incident angle that can realize all the time two bundle laser beam is 90 degree, the variety of issue of having mentioned above well having solved, reduce cost, saved the space.
according to an embodiment, a kind of stimulated Brillouin scattering generation container is provided, comprise the parabolic mirror that sets gradually along light path, part transmissive portion catoptron, spherical SBS medi um container and laser instrument, it is characterized in that: the center of described parabolic mirror has for the through hole by laser beam, described part transmissive portion catoptron is positioned on paraboloidal first focus of parabolic mirror, the centre of sphere of described spherical SBS medi um container is positioned on described paraboloidal the second focus, described part transmissive portion catoptron is rotatable, its rotating shaft is positioned on the first focus.
According to an embodiment, described part transmissive portion catoptron is semi-transparent semi-reflecting lens.
according to an other embodiment, a kind of method that realizes the multi-angle stimulated Brillouin scattering is provided, laser beam incident is arrived in the through hole at parabolic mirror center, then incide on part transmissive portion catoptron, the light beam that sees through is called the first light beam, the light beam that is reflected is called the second light beam, after this first light beam of transmission passes through the centre of sphere of spherical SBS medi um container, also pass the described centre of sphere after the second light beam polished object face mirror reflects that is reflected, change the first light beam and the second light beam at the angle at described centre of sphere place by rotating part transmissive portion catoptron.
Description of drawings
Accompanying drawing 1 is the schematic diagram of the container that occurs of the stimulated Brillouin scattering for liquid or gas of the present invention;
In above-mentioned figure, 1 expression parabolic mirror, 2 expression semi-transparent semi-reflecting lens, 3 expression SBS medi um containers, 4 and 5 expressions are used for the two bundle laser beam that stimulated Brillouin scattering occurs, a focus of 6 expression parabolic mirrors, 7 expression laser instruments.
Embodiment
The below will describe container of the present invention in detail on basis by reference to the accompanying drawings, the SBS medi um container of 3 expression printing opacities, it is spheroidal, be used for accommodating liquid or the gas that carries out stimulated Brillouin scattering, this container is provided be used to the import that pours into and/or pour out SBS medi um and/or outlet, belong to well-known to those skilled in the art due to import and outlet being set at such device, no longer be described in detail for the setting of import and outlet.The centre of sphere of the SBS medi um container of this spheroidal is positioned on a focus of parabolic mirror 1, and semi-transparent semi-reflecting lens 2 is positioned on the another one focus of parabolic mirror.The center of parabolic mirror 1 wherein is provided with the through hole that passes for laser.when carrying out stimulated Brillouin scattering, at first be full of in the SBS medi um container be used to the liquid that carries out stimulated Brillouin scattering or gas, then with the through-hole alignment at the laser beam of laser instrument emission and parabolic mirror 1 center, make this laser beam pass this through hole, laser beam incides on the semi-transparent semi-reflecting lens 2 that is positioned on the first focus after passing this through hole, be divided into two-beam, wherein the light of transmission is light beam 5, be directly incident in the SBS medi um container of spheroidal and pass the centre of sphere of this ball, the light that is reflected in addition is light beam 4, light beam 4 incides on parabolic mirror 1, and then polished object face mirror reflects, the light of polished object face mirror reflects can incide on the centre of sphere of described ball, and semi-transparent semi-reflecting lens 2 wherein is rotatable, like this, can realize that by rotation semi-transparent semi-reflecting lens 2 light beam 4 and light beam 5 are sentenced different angles at the centre of sphere crossing.Be positioned at a focus of parabolic mirror due to semi-transparent semi-reflecting lens, and the centre of sphere of ball is positioned on the another one focus, so that reflected by semi-transparent semi-reflecting lens and incide on parabolic mirror again that the light of polished object face mirror reflects must pass through the centre of sphere, must pass through the another one focus because send light by a paraboloidal focus through after parabolic reflector.Like this, by the design cleverly of this device, obtain the crossing effect of different angles when having realized the laser beam beam splitting, thereby can realize stimulated Brillouin scattering experiment at any angle, because two bundle laser beam are all passed the center of circle, so the incident angle of two bundle laser beam on sphere is all 90 degree forever.
In the present invention, owing to having utilized semi-transparent semi-reflecting lens 2 to carry out beam splitting, test so this device can not be realized the stimulated Brillouin scattering of going the same way fully, the angle of its realization should be greater than 0 less than 90 degree.
Moreover semi-transparent semi-reflecting lens 2 is not that to necessarily require be semi-transparent semi-reflecting, and it can be a part reflecting part diaphotoscope, can determine according to the needs of concrete stimulated Brillouin scattering as for the ratio of reflection and transmission.
