Description
Technical field
The present invention relates to field of laser device technology, particularly relate to a kind of pulse laser.
Background technology
Power is high, volume is little, reliability high, has been widely used in civilian survey because it has for pulse laser
Away from fields such as, civilian detections, additionally also there is significant role in the military field such as laser fuze, laser guidance.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 the mode generally using laser light source evenly distributed realizes
The output that 220W is certain, laser beam is sent by glass optical window, realizes the beam angle of 60 ° after slow axis carries out optical beam-expanding
Degree.
The inferior position of prior art: laser light source is evenly distributed, primary light field intensity is uniformly distributed, after slow axis expands
The decay of light field edge merit intensity values is very fast, in 60 ° of effective angles, and 2 times of zone line light intensity value approximation edge area light intensity values,
Thus cause carrying interior equalization of intensity poor, system debug tolerance is little.
Summary of the invention
The technical problem to be solved is to provide a kind of pulse laser, and described laser instrument decreases zone line
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, the technical solution used in the present invention is: a kind of pulse laser, including insulation lining
Bottom, described dielectric substrate layers is provided with metal level, and described metal level is provided with light source, it is characterised in that: described light source is provided with
More than four, all of light source is a line arrangement, and described light source is divided into more than two, is often provided with plural in group light source
Light source, wherein adjacent in two groups of light sources distance D1 between two light sources is more than distance D2 between light source in often group light source.
Further technical scheme is: described light source is provided with 6, is divided into two groups, left and right, is often provided with three in group light source
Individual light source.
Further technical scheme is: often in group light source, distance D2 between light source is identical.
Further technical scheme is: often in group light source, the number of light source is identical.
Use and have the beneficial effects that produced by technique scheme: adjacent in two groups of light sources in described laser instrument two
Distance between light source, more than distance between light source in often group 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.
