Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art
Member is further appreciated by the present invention, but limits the present invention the most in any form.It should be pointed out that, the common skill to this area
For art personnel, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into
Protection scope of the present invention.
It is divided into three masters according to the communication system based on sunshine pump-coupling spatial light carrier generator that the present invention proposes
Want operational module, sunshine polymerization segmentation module, pumping operational module, modulation communication module.
The function of sunshine polymerization segmentation module is to assemble solar energy and energy is split according to different frequency ranges,
Segmentation Hou Ge road light source is transported to subsequent work module.Spectrum segmentation refers to the absorption according to different pumping operation materials
Frequency range carries out classifying rationally.Sunshine polymerization segmentation module is mainly made up of four parts: sunlight tracking system, optically focused system
System, spectrum segmenting system, output coupled system.
The core of sunshine polymerization segmentation module is spectrum segmenting system.Described sunshine polymerization segmentation module major function is
The sunlight light source of wide-band is divided into several narrow-band light sources, generates the arrowband pumping that each pumping operation material needs
Light, and couple be input at each pumping operation material after produce light carrier, simultaneously the light source natural filtration of useless frequency band
The heat energy input of reduction system.
The function of pumping operational module is to produce multi-path light carrier wave, there is multiple absorption in described pumping operational module simultaneously
The optical pumping light carrier generator that frequency range is different, configures heat control system and temperature-sensing system at pumping operation material, uses
To control pumping operation material temperature.Pumping operation material in the present invention, in order to improve absorption efficiency and reduce heat consumption, is adopted
Deploying to ensure effective monitoring and control of illegal activities doped metal ion by nanometer gradient doping means, the operation material of nanometer gradient doping can be axially
Realize the uniform pickup to incident light.
The core of pumping operational module is pumping operation material.Traditional pumping operation material uses Uniform Doped or limited
The Doping of exponent number, it is too high, in pumping material, along entering that this mode can cause pumping material end face to absorb heat energy
Penetrate light and be formed radially the temperature difference, cause Temperature grade thermal effect and end-face deformation thermal lensing effect, destruction work material performance.
The principle of nanometer gradient doping is to utilize non-uniform doping, makes pump energy each several part uniform pickup in working media,
And then reduce the unbalanced of heat distribution.In the case of not reducing total absorption efficiency, both it was avoided that local temperature was too high,
The generation of temperature step can be avoided again.
The major function of modulation communication module is by the middle of modulate communications information to carrier wave, and light beam carries out shaping and defeated
Go out.Described modulation communication module is configured with signal source, light carrier modulator and optical outputting system.
Existing spectral unmixing technology, is mainly used in the two or more narrow-band light source of segmentation or monochromatic source, profit
Different by each monochromatic source refractive index in media as well, by prism, each light source is spatially segregated from, regathers
In corresponding processing unit.
And sunshine belongs to wide spectrum light source, the narrow frequency range light source that isolation is high, and rib cannot be obtained by conventional treatment mode
Sunlight after the effect of dispersion of mirror will converge dissipates again, output pumping optical power density will be made to reduce, and then cause system
Efficiency reduces.
As it is shown on figure 3, utilize the solar spectrum segmenting system that the Transflective mirror of multiple plating different medium film forms, this
Design can make full use of the wavelength between different medium film and select interval, isolates high power close the sunlight after converging
Degree, the pump light source of narrow-band, do not cause the secondary of light source to dissipate, and can naturally leak out useless frequency range energy of light source,
The accumulation of heat of minimizing system, the loss of system effective light energy is little.Multi-path light carrier wave pumping skill based on solar spectrum segmentation
Art, the sunshine after segmentation can have the operation material of different absorption spectrum with pumping, improves solar energy further
Utilization rate.The advantage of multi-path light carrier wave pump technology resides in reduced energy waste during the single operation material of pumping, simultaneously
Avoid producing many waste heat energies owing to invalid pump energy irradiates operation material, bring thermal control pressure to system.Pumping works
Material uses nanometer gradient doping means to process, and makes operation material have high-selenium corn efficiency and uniform heat distribution, reduces
The thermal control pressure of system.It is unbalanced existing that the pumping operation material of Uniform Doped can be upwardly formed heat energy distribution in incident light side
As, producing heat near the position of incidence end high, produce heat away from incidence end position low, the unbalanced meeting of heat causes
Operation material absorption efficiency reduces, and the light carrier quality also resulting in generation declines.
Nanometer gradient doping technology refers on nanoscale, makes the metal ion mixing concentration of pumping operation material enter
Penetrate and be incremented by light direction, make pumping operation material reduce absorption at the high-energy-density of incidence end, along with in operation material
Portion's incident optical energy metric density is gradually reduced and is continuously increased absorption efficiency, thus realizes the heat energy equilibrium of whole operation material.
Specifically, as it is shown in figure 1, sunshine polymerization segmentation module includes: condenser system, sunlight tracking system, light
Spectrum segmenting system, output coupled system.Specifically, as in figure 2 it is shown, described condenser system by Fresnel Lenses face and

As it is shown on figure 3, pumping operational module is mainly controlled by light on-off switch, sunshine pump laser, TEMP
System forms.As shown in Figure 4, modulation communication district mainly by signal source, laser signal modulating system, optical shaping system,
And optical antenna composition.
Further, the work of the communication system based on sunshine pump-coupling spatial light carrier generator in the present invention
Process is as follows:
Step 1: sunlight tracking system according to position of sun adjust Fresnel Lenses face and 3D-CPC laser pump cavity towards,
Make Fresnel Lenses face vertical with sunshine incident direction all the time；
Step 2: the secondary of the incident sunshine focussing force through Fresnel Lenses face and 3D-CPC laser pump cavity gathers
Jiaozhuo use, forms the solar-pumped light source with high power density；
Step 3: the solar-pumped light source of high power density sequentially passes through one or more plating deielectric-coating Transflective mirror, makes
Spectrum is separated according to the demand of different pumping operation materials, it is simple to each pumping operation material independence pumping follow-up produces and swashs
Light carrier；Wherein, sunshine pump light source is a full frequency band white noise light source, and the suction of light carrier pumping operation material
Receive frequency range relative narrower, it is therefore desirable to sunshine light source is carried out spectrum imaging；
Step 4: the pump light source after segmentation carries out pumping also according to the light path shown in Fig. 4 to corresponding pumping operation material
Produce continuous laser carrier wave, containing temperature sensor in each pump laser, when operating temperature is higher than the steady of operation material
When determining the state temperature upper limit, shutdown signal is sent to light on-off switch by TEMP control system, cuts off light source input；
Step 5: the multi-path persistent laser carrier that pumping operational module produces enters modulation communication module and carries out laser signal tune
System and transmitting, signal source produces modulated signal, and modulated signal is transferred to modulating system, and then is modulated light carrier,
Light carrier after modulation warp after optical shaping is sent to external world by optical antenna.
