In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Using power synthetic technique and automatic precision focusing technology, realized in 1km apart from interior to " low slow small " aircraft mesh
Target is intercepted and destroyed, relative to the cost reduced at present in the weapon laser system ground more than one hundred million members easily, the program it is excellent
Gesture is the cost for greatling save a whole set of laser defence system, and under current laser technique state of development, is ensuring
On the premise of system intercepts validity, the laser defence system is set to possess higher reliability, mobility and the ability that fights one battle after another.
Main optical path subsystem uses Shared aperture light path design, and to optical fiber laser, (optical fiber laser carries pre-collimated first
Function) laser beam that sends carries out closing beam by closing beam fast anti-mirror 4 and CCD3 and handles, and closes laser beam after beam processing fast by second
Anti- mirror 5 is reflected to spectroscope 6, and the laser beam that the second fast anti-mirror 5 reflects is all-trans to the first fast anti-mirror 8 by spectroscope 6, and first is fast anti-
The light that spectroscope 6 reflects is reflected to pyramid mirror 10 and transmitted by mirror 8, and (this case is by primary mirror 11 and secondary mirror 12 for the light of transmission
Off-axis cassette mirror laser emission optical system) launch from window.By adjusting the spacing between secondary mirror and primary mirror, realize and swash
Focusing of the light beam on far field objects.A laser beam part is transmitted by pyramid mirror 10, and another part is reflected by pyramid mirror 10,
Decay through attenuator 9, the first fast anti-mirror 8 reflects, and wedge mirror 7 is reflected into precision tracking detection system 13；What target was reflected
Light, main optical path is entered after window 14, is transmitted successively along secondary mirror 12, primary mirror 11, pyramid mirror 10, the first fast anti-reflection of mirror 8 and
The light that spectroscope 6 is transmitted enters precision tracking detection system 13 and forms image, realizes the acquisition and tracking to target.Main optical path
As shown in Figure 1.
Specific implementation is as follows：
Laser transmitting system is emulated using LightTools, system emulation figure is illustrated in figure 2, light source places master
The mirror left side, optical fiber laser is 7, forms the synthesis light beam that 6 tunnels surround 1 tunnel, and the part for blocking central light beam center carrys out mould
Intend hollow beam.The size of focusing distance focal beam spot in 0.5km, 1km is sets forth in Fig. 3, the shape of beam laser beam is closed
Shape has no effect on the shape of focal beam spot, and focal beam spot is a round hot spot.
With domestic current technology level, in laser weapon equipmentization application aspect, space power synthesis technical system ratio
The high-power technical system of single channel has obvious advantage.
1) influence of the beam quality to far field focus
Laser beam quality standard is M2The factor, it is defined as：
ω and ω in formula0(beamwidth is fixed by second moment for respectively tested actual light beam and the waist width of fundamental-mode gaussian beam
Justice), θ and θ0Respectively it is tested the far-field divergence angle of actual light beam and fundamental-mode gaussian beam.And laser far field facula area is：
Therefore, laser far field Bright efficacy and density is inversely proportional with facula area, laser far field Bright efficacy and density and light beam
Quality factor square is inversely proportional, and wherein L is the distance with target.
For example, at present, the beam quality M of the domestic myriawatt solid state laser of highest level 12The factor is about 2.5 or so, and skill
The beam quality M of 1000 watts of ripe optical fiber lasers of art2The factor is about 1.4 or so, using same optical system, then and 10,000
Watt solid state laser is about 3.2 times of 1000 watts of optical fiber lasers in far-field spot area, due to the strike efficiency of laser weapon
It is mainly relevant with laser spot power density, therefore, in theory, it is only necessary to which 3 1000 watts of optical fiber lasers carry out spatial power
Synthesis can reach the strike efficiency same with 1 myriawatt solid state laser, be carried out according to 10 1000 watts of optical fiber lasers empty
Between synthesize, power output equally reaches 1 myriawatt, then its fighting efficiency far will surpass 1 myriawatt solid state laser.
2) myriawatt level laser stream time is short, influence confrontation multi-batch targets
Single channel high power laser is larger due to its single channel power output, and electro-optical efficiency is relatively low, and opposite heat tube reason is required
Higher, stream time is shorter.
At present, the myriawatt level solid state laser stream time of domestic highest level is 30s, and operating interval is long
Up to more than 5min, it is impossible to realize that the strike to multi-batch targets is resisted.
And for the other optical fiber laser of multikilowatt, stream time is not limited substantially, it disclosure satisfy that pair
The continuous strike operation requirement of multi-batch targets.
3) manufacturing cost
With domestic current technology level, the development cost of myriawatt level solid state laser about more than 40,000,000, due to
Its optical system weight is up to 400 kilograms or so, and servo-drive system, pointing system pressure are larger, cause whole system cost higher, about
1.2 hundred million or so, and the price of multikilowatt high light beam quality optical fiber laser is about 400,000 or so, even if being carried out using 12 empty
Between power combing, whole system total cost is about 30,000,000 or so, still differ as many as 4 times.
In summary, the laser light source beam quality used by space power synthesis technical system laser weapon is much excellent
In separate unit high power laser, its far field focus capacity superiority is fairly obvious, can reach more preferable fighting effect, and
Its continuous striking capabilities to multi-batch targets is higher, and manufacturing cost is lower, therefore, just laser technique level domestic at present
For, it is the reasonable selection for realizing laser weapon equipment using many space power synthesis technical systems.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
