Description
Technical field
It the utility model is related to laser technology field, and in particular to a kind of laser closes beam system.
Background technology
Sharp combiner is the process of a raising far-field laser power density, can be in the constant situation of former power output
Under, effectively improve laser power density.Present laser closes beam technology and device, either laterally closes beam or beam is closed in longitudinal direction,
The problem of poor expandability all be present, i.e. the complexity of system steeply rises with the increase for closing beam way, it is impossible to according to
Need the scale of simply and flexibly expansion of laser light conjunction beam.
Utility model content
The purpose of this utility model is to provide a kind of annular spread laser and closes beam system, realize well annular+in
The conjunction Shu Wenti of heart distribution laser array output laser beam, and the system closes beam efficiency high, simple in construction, scalability
It is good.
To achieve the above object, the utility model employs following technical scheme：A kind of photosynthetic beam system, including laser
Array, speculum group, laser array, which includes being located at along several outer lasers of same even circumferential distribution and one, to be somebody's turn to do
The interior laser in the circumference center of circle, speculum group include external reflectance microscope group and internal reflection microscope group, each eyeglass of external reflectance microscope group with it is outer
Laser corresponds, and each eyeglass of external reflectance microscope group be located at the center line surface of the light path of outer laser and towards interior laser
Device direction is tilted horizontal by 45 ° of angles；The number of lenses of internal reflection microscope group is identical with external reflectance microscope group, internal reflection microscope group
Each eyeglass surrounds interior laser annular spread, and is corresponded with each eyeglass of external reflectance microscope group, any two corresponding mirrors
The reflecting surface of piece is relative and is parallel to each other.
Further improvement as above-mentioned technical proposal：
The laser, which closes beam system, also includes the governor motion of regulation lens angle.
As shown from the above technical solution, the utility model includes laser array, speculum group and lens adjustment mechanism group
Into, two groups of speculum groups for being circumferentially uniformly distributed and being parallel to each other, set with level in 45 ° of angles, one-to-one corresponding are employed,
Can by the laser beam being distributed along same even circumferential and positioned at the center of circle laser beam close beam, solve annular+in
The heart is distributed the conjunction Shu Wenti of laser beam.The system architecture is simple, and closes beam efficiency high, and scalability is good, well should have
Use prospect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is speculum group operating diagram of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, the laser of the present embodiment closes beam system, including laser array 1, speculum group 2, the laser
Array 1 includes several outer lasers 11 along the distribution of same even circumferential and the interior laser in the position circumference center of circle
12, the speculum group 2 includes external reflectance microscope group 21 and internal reflection microscope group 22, and each eyeglass of the external reflectance microscope group 21 swashs with outer
Light device 11 corresponds, and each eyeglass of external reflectance microscope group 21 is located at directly over the center line of the light path of outer laser 11 and towards interior
The direction of laser 12 is tilted horizontal by 45 ° of angles；The number of lenses of the internal reflection microscope group 22 and the phase of external reflectance microscope group 21
Together, each eyeglass of internal reflection microscope group 22 surrounds the interior annular spread of laser 12, and with a pair of each eyeglass 1 of external reflectance microscope group 21
Should, the reflecting surface of any two corresponding eyeglasses is relative and is parallel to each other.The circumferentially equally distributed light beam of laser 11 warp
Cross external reflectance microscope group 21 reflect after, directive internal reflection microscope group 22, due to inside and outside speculum group relative to and it is parallel and with ground into
45 ° of angles, after the reflection of internal reflection microscope group 22, laser beam keeps former outbound course, and with the laser positioned at home position
The beam direction of device 12 is consistent, so as to realize the conjunction beam of 1 all light beams of laser array.The lens dimension of internal reflection microscope group 22 is got over
Small, final beam separation is smaller, and conjunction Shu Xiaoguo is better, and the utility model can be according to laser array scale, flexible expansion, tool
There is preferable scalability.The utility model can also set governor motion, for adjusting the eyeglass of speculum group 2, be easy to pacify
Regulation in dress and use.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
