Description
Technical field
This utility model is related to field of laser device technology, more particularly, to a kind of pulse laser.
Background technology
Pulse laser because its have power height, small volume, reliability high the features such as, be widely used in civilian survey
Away from fields such as, civilian detections, in addition also there is significant role in military fields such as laser fuze, laser guidances.Pulse laser is made
For the core component of laser fuze, laser instrument is proposed high-peak power, light field uniformly, the requirement of small size, low cost.Domestic
The pulse laser light-source structure of outer like product is relatively fixed, and generally to realize by the way of laser light source is evenly distributed
The certain output of 220W, laser beam is sent by glass optical window, realizes 60 ° of beam angle after slow axis carries out optical beam-expanding
Degree.
The inferior position of prior art：Laser light source is in evenly distributed, and original distribution of light intensity is uniformly distributed, after expanding through slow axis
The decay of light field edge work(intensity values is very fast, in 60 ° of effective angles, 2 times of zone line light intensity value approximate edge area light intensity values,
Thus leading to carry interior equalization of intensity poor, system debug tolerance is little.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pulse laser, and described laser instrument decreases centre
Region light intensity value, increases marginal area light intensity value, therefore improves light field uniformity, can obtain uniformity in optimal band.
For solving above-mentioned technical problem, technical solution adopted in the utility model is：A kind of pulse laser, including absolutely
Edge substrate layer, described dielectric substrate layers are provided with metal level, described metal level be provided with light source it is characterised in that：Described light source
Be provided with more than four, all of light source be in a line arrange, described light source be divided into more than two, be provided with every group of light source two with
On light source, in wherein two groups light sources, the distance between two adjacent light sources D1 is more than the distance between light source in every group of light source
D2.
Further technical scheme is：Described light source is provided with 6, is divided into two groups of left and right, is provided with three in every group of light source
Individual light source.
Further technical scheme is：In every group of light source, the distance between light source D2 is identical.
Further technical scheme is：In every group of light source, the number of light source is identical.
Have the beneficial effects that using produced by technique scheme：Adjacent two in two groups of light sources in described laser instrument
The distance between light source is more than the distance between light source in every group of light source, decreases zone line light intensity value, increases marginal area
Light intensity value, therefore improves light field uniformity, can obtain uniformity in optimal band.

Specific embodiment
With reference to the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Elaborate a lot of details in the following description in order to fully understand this utility model, but this practicality is new
Type can also be different from alternate manner described here to implement using other, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore this utility model is not limited by following public specific embodiment.
Overall, the utility model discloses a kind of pulse laser, including dielectric substrate layers 1, described dielectric substrate layers 1
It is provided with metal level 2, described metal level 2 is provided with light source 3, and above content is same as the prior art, will not be described here.This reality
It is different from place of prior art with new：Described light source 3 is provided with more than four, and all of light source 3 is in that a line arranges, described
Light source is divided into more than two, is provided with plural light source 3, two adjacent light sources in wherein two groups light sources in every group of light source
The distance between 3 D1 are more than the distance between light source 3 D2 in every group of light source, and in every group of light source, the distance between light source 3 D2 is identical,
In every group of light source, the number of light source 3 is identical.
In an embodiment of the present utility model, as shown in figure 1, described light source 3 is provided with 6, it is divided into two groups of left and right,
It is provided with three light sources 3, in every group of light source, the distance between light source 3 D2 is identical in every group of light source.
Wherein, Fig. 2 be light source in laser instrument evenly distributed under optical field distribution figure；Fig. 3 is this utility model embodiment
The optical field distribution figure of described laser instrument；Fig. 4 is that evenly distributed and light source uneven arrangement the light-source structure of light source optimizes comparison diagram.
Figure 4, it is seen that laser instrument described in the utility model decreases zone line light intensity value, increase marginal area light intensity value,
