Abstract
The utility model provides a stimulated brillouin scattering reinforcing means, the device be to pulsed laser that brand -new general type and an in the form incides the stimulated brillouin scattering medium once more that the continuous laser of all is suitable for, its adopt holophote and dichroic mirror with remaining exciting light with the same light path of pilot light to once more make full use of remaining exciting light.
Description
Technical field
This utility model relates to stimulated Brillouin scattering, particularly relates to and a kind of improves the device that stimulated Brillouin scattering light is strong, belongs to photoelectron technical field。
Background technology
Stimulated Brillouin scattering belongs to a kind of very important scattering phenomenon in the middle of nonlinear scattering, in prior art a lot of about the research of stimulated Brillouin scattering, wherein it is required for could realizing generation and the observation of 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 excitation light same light path, another is that excitation light exists intersecting angle with pump light, stimulated Brillouin scattering for both forms, for the first situation, if in liquid or gas medium carry out stimulated Brillouin scattering, then need to house specially the container of SBS medi um, light path design is carried out in outside, flashlight and excitation light same light path in the middle of medium are propagated, or simply squeeze into excitation light in media as well, utilize spontaneous Brillouin scattering as flashlight, and for fiber medium, owing to light transmission in optical fiber is all strictly be limited in inside of optical fibre, so light path must be same light path, stimulated Brillouin scattering for same light path, cell therefor is generally the rectangular or square when of transparent cylindrical shape or rule, have only at the incident laser producing flashlight of same light path order and the laser for amplifying when carrying out stimulated Brillouin scattering experiment, flashlight and excitation light are existed to the stimulated Brillouin scattering of angle, then cell therefor needs specialization to design, the such as luminous reflectance loss in order to minimize, needing the intersecting angle keeping flashlight with encouraging light is 90 degree, but, no matter for which kind of situation, excitation light is all once pass through SBS medi um, actually, when excitation light is once by after medium, the part that its energy is transformed into flashlight is simply seldom a part of, major part excitation light just slatterns after passage, such result is just so that the flashlight of excited Brillouin can not be greatly enhanced, and also cause the significant wastage of the energy。
This utility model is aiming at what the problems referred to above put forward, little by force to solve stimulated Brillouin scattering light in prior art, the problem that excitation light waste is serious。
Utility model content
This utility model provides a kind of brand-new universal stimulated Brillouin scattering intensifier, this device is all applicable to pulse laser and continuous laser, it adopts completely reflecting mirror and dichroic mirror to be again incident in SBS medi um with the form with flashlight same light path by remaining excitation light, thus again taking full advantage of remaining excitation light。
According to an embodiment of the present utility model, provide a kind of universal stimulated Brillouin scattering intensifier, this device includes: excitation radiant (1), shaping lens (2), dichroic mirror (3), SBS medi um (5), first completely reflecting mirror (6), second completely reflecting mirror (7), flashlight light source (8), it is characterized in that: their relation that arranges is: excitation radiant (1), shaping lens (2), SBS medi um (5) and the first completely reflecting mirror (6) set gradually along light path order, the flashlight that flashlight light source (8) sends enters SBS medi um (5) through dichroic mirror (3), SBS medi um (5) intersects with non-zero angle with excitation light, reflexed to completely reflecting mirror (7) from the excitation light of SBS medi um (5) transmission by the first completely reflecting mirror (6), then it is totally reflected mirror (7) and reflexes on dichroic mirror (3), dichroic mirror (3) for flashlight transmission for excitation luminous reflectance, the excitation light incided on dichroic mirror (3) is reflexed in SBS medi um (5) with the form with flashlight same light path by dichroic mirror (3)。
According to an other embodiment of the present utility model, also including the semi-transparent semi-reflecting lens (9) being positioned between flashlight light source (8) and dichroic mirror (3), backward scattered stimulated Brillouin scattering flashlight reflexes on detector (10) via semi-transparent semi-reflecting lens (9)。
According to an embodiment of the present utility model, this device is all applicable for pulse laser and continuous laser。
Accompanying drawing explanation
Accompanying drawing 1 be universal stimulated Brillouin scattering intensifier of the present utility model schematic diagram。
In above-mentioned accompanying drawing, 1 represents excitation radiant, and 2 represent shaping lens, and 3 represent dichroic mirror, and 5 represent SBS medi um, and 6-7 represents completely reflecting mirror, and 9 represent semi-transparent semi-reflecting lens, and 10 represent detector, and 8 represent flashlight light source。
Detailed description of the invention
Of the present utility model embodiment will be described in detail below on the basis in conjunction with accompanying drawing 1, in this embodiment, wherein flashlight intersects with non-zero angle in SBS medi um 5 inside with excitation light, this device includes: excitation radiant 1, shaping lens 2, dichroic mirror 3, SBS medi um 5, completely reflecting mirror 6-7, detector 10, flashlight light source 8, partial mirror 9, their relation that arranges is: excitation radiant 1, shaping lens 2, SBS medi um 5 and completely reflecting mirror 6 set gradually along light path order, the flashlight that flashlight light source 8 sends enters SBS medi um 5 sequentially through semi-transparent semi-reflecting lens 9 and dichroic mirror 3, SBS medi um intersects with non-zero angle with excitation light, it is totally reflected mirror 6 from the excitation light of SBS medi um 5 transmission and reflexes to completely reflecting mirror 7, then it is totally reflected mirror 7 and reflexes on dichroic mirror 3, dichroic mirror 3 for flashlight transmission for excitation luminous reflectance, the excitation light incided on dichroic mirror 3 is reflexed in SBS medi um 5 by dichroic mirror 3 with the form with flashlight same light path, and backward stimulated Brillouin scattering light incides on semi-transparent semi-reflecting lens 9 through dichroic mirror 3, reflexed on detector 10 by semi-transparent semi-reflecting lens 9。
Operation principle and process below for above-described embodiment are described in detail, owing to the generation of stimulated Brillouin scattering belongs to technology known in the field with detection, so being no longer described in detail for this part, in the light path focusing on excitation light described below, when encouraging light to intersect first in media as well with flashlight, flashlight is amplified by excitation light, remaining excitation light then incides on dichroic mirror 3 via completely reflecting mirror 6 and 7, owing to dichroic mirror 3 just reflects for excitation, and it is that the form with flashlight same light path reflects, here it is make remaining excitation light incident SBS medi um again coaxially interacts with flashlight, this mode not only makes remaining excitation light again be fully used, and again with time change the mode of anterior cruciate, but become coaxial mode, obviously, it is bigger that coaxial mode intersects area, action time is longer, so that excitation light obtains utilizing fully very much。
It will be apparent that no matter above-mentioned device is for pulse laser, or it is all applicable for continuous laser, so stimulated Brillouin scattering intensifier of the present utility model is a kind of universal intensifier。
