Description
Technical field
The utility model relates to stimulated Brillouin scattering, particularly relates to a kind of stimulated scattering intensifier avoiding exciting light light source to damage, and can improve stimulated Brillouin scattering light strong, belong to photoelectron technical field.
Background technology
Stimulated Brillouin scattering belongs to a kind of very important scattering phenomenon in the middle of nonlinear scattering, a lot of about the research of stimulated Brillouin scattering in prior art, wherein all need generation and the observation that could realize stimulated Brillouin scattering by specific device and light path design, the stimulated Brillouin scattering device of prior art is generally divided into two kinds in the design of light path, one is flashlight and exciting light same light path, and another is that exciting light and pump light exist intersecting angle.The stimulated Brillouin scattering of these two kinds of forms, for the first situation, if carry out stimulated Brillouin scattering in liquid or gas medium, then need the container holding SBS medi um specially, light path design is carried out in outside, flashlight and exciting light same light path in the middle of medium is propagated, or just squeezes into exciting light in media as well, utilize spontaneous Brillouin scattering as flashlight.And for fiber medium, because the transmission of light in optical fiber is all strictly be limited in inside of optical fibre, so light must be same light path, for the stimulated Brillouin scattering of same light path, cell therefor is generally rectangle or the square of transparent cylindrical shape or rule, only needs at the same light path order incident generation laser of flashlight and the laser for amplifying when carrying out stimulated Brillouin scattering experiment.For the second situation, there is the stimulated Brillouin scattering of angle in flashlight and exciting light, then cell therefor needs specialization to design, such as, minimizing in order to light reflection loss, needs the intersecting angle of inhibit signal light and exciting light to be 90 degree.But no matter for which kind of situation, exciting light is all once pass through SBS medi um.In fact, when exciting light is once by after medium, the part that its energy is transformed into flashlight is just seldom a part of, major part exciting light has just slatterned after passage, such result is exactly that the flashlight of excited Brillouin can not be greatly enhanced, and causes the significant wastage of the energy.Meanwhile, also there is a problem, be exactly that exciting light may turn back in the light source of exciting light, thus may damage be produced to exciting light light source.
The utility model puts forward for the problems referred to above, little by force to solve stimulated Brillouin scattering light in prior art, and exciting light waste is serious and may produce to exciting light light source the problem damaged.
Utility model content
The utility model provides a kind of stimulated scattering intensifier avoiding exciting light light source to damage, and this device can not only take full advantage of remaining exciting light again, plays a very good protection for exciting light light source simultaneously.
According to an embodiment of the present utility model, provide a kind of stimulated scattering intensifier avoiding exciting light light source to damage, this device comprises: exciting light light source 1, polarizing beam splitter mirror 2, quarter-wave plate 3, stimulated scattering medium 4, and completely reflecting mirror 5, their pass that arranges is: exciting light light source 1, polarizing beam splitter mirror 2, quarter-wave plate 3, stimulated scattering medium 4, and completely reflecting mirror 5 sets gradually along light path, wherein except polarizing beam splitter mirror 2, all the other elements all intersect vertically with light path, polarizing beam splitter mirror 2 becomes miter angle to arrange with light path, described exciting light light source is linear polarization light source, what arrange polarizing beam splitter mirror 2 puts direction, the linear polarization exciting light that exciting light source 1 is sent can whole polarizing beam splitter mirrors 2 described in transmission.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the stimulated scattering intensifier avoiding exciting light light source to damage of the present utility model.
In above-mentioned accompanying drawing, 1 represents exciting light light source, and 2 represent polarizing beam splitter mirror, and 3 represent quarter-wave plate, and 4 represent stimulated scattering medium, and 5 represent completely reflecting mirror.
Embodiment
Below by by reference to the accompanying drawings 1 basis on describe embodiment of the present utility model in detail, in this embodiment, stimulated scattering both can be stimulated Brillouin scattering, also can be stimulated Raman scattering, stimulated Brillouin scattering is back scattering, stimulated Raman scattering forward scattering, no matter be wherein stimulated Brillouin scattering or stimulated Raman scattering, flashlight wherein all originates from the spontaneous scattering in stimulated scattering medium, this device comprises exciting light light source 1, polarizing beam splitter mirror 2, quarter-wave plate 3, stimulated scattering medium 4, and completely reflecting mirror 5, their pass that arranges is: exciting light light source 1, polarizing beam splitter mirror 2, quarter-wave plate 3, stimulated scattering medium 4, and completely reflecting mirror 5 sets gradually along light path, wherein except polarizing beam splitter mirror 2, all the other elements all intersect vertically with light path, polarizing beam splitter mirror 2 becomes miter angle to arrange with light path, described exciting light light source is linear polarization light source.
Describe operation principle of the present utility model and process in detail below, the exciting light of the linear polarization that exciting light source 1 sends, what arrange polarizing beam splitter mirror 2 puts direction, the linear polarization exciting light that exciting light source 1 is sent can whole polarizing beam splitter mirrors 2 described in transmission, incide after quarter-wave plate 3 in gain media 4 from the exciting light of polarizing beam splitter mirror 2 transmission, exciting light transmitted through gain media 4 impinges perpendicularly on completely reflecting mirror 5, reflected by the former road of completely reflecting mirror and again enter stimulated scattering medium 4, exciting light all obtains utilization in the process passing twice through stimulated scattering medium 4, also namely exciting light has been utilized twice, thus greatly improve the utilization ratio of exciting light.After again passing stimulated scattering medium 4; again through 1/4th slides; owing to having passed twice through quarter-wave plate before and after exciting light; the polarization direction of exciting light is now made to there occurs the rotation of 90 degree; light path is left when its again incident polarization beam splitter 2 being just polarized beam splitter 2 reflection; thus can not incide in exciting light light source, thus protective effect is served for exciting light light source.
