Dab tsi yog Txoj Kev Tiv Thaiv Laser thiab Tshuab?

Kev Tiv Thaiv Lasercov txheej txheem thiab thev naus laus zis feem ntau suav nrog cov hauv qab no:
Thawj yog lim tshuab, uas yog ib txoj kev tiv thaiv raws li cov qauv kev kho qhov muag, suav nrog cov lim dej nqus, cov ntxaij lim dej, cov ntxaij lim dej-reflection filters, coherent filters, pleated filters thiab Holographic filters, thiab lwm yam.
Qhov thib ob yog laser tiv thaiv tsom iav, uas tuaj yeem tiv thaiv tsis tau tsuas yog lasers ntawm cov wavelengths tshwj xeeb, tab sis kuj tag nrho cov wavelengths ntawm lub teeb, tab sis koj yuav tsum ceev faj tsis txhob saib ncaj qha ntawm lub laser thaum siv lawv.

Tsis tas li ntawd, kev tiv thaiv qhov muag tsis pom kev thiab kev tiv thaiv laser glare kuj yog lub hom phiaj tseem ceeb ntawm kev tiv thaiv laser. Cov qub feem ntau suav nrog kev siv cov ntaub ntawv tiv thaiv thiab kev siv cov duab kos duab, thaum lub sijhawm tom kawg suav nrog kev tsim kho qhov muag thiab cov duab ua cov thev naus laus zis.

Tsis tas li ntawd, muaj kev tiv thaiv thev naus laus zis raws li cov qauv kev kho qhov muag uas tsis yog-linear, xws li optical switching filters, self-focusing/self-defocusing limiters, thermal lens limiting, etc. Txhua txoj hauv kev thiab thev naus laus zis no muaj qhov zoo thiab qhov tsis zoo, thiab kev tiv thaiv tsim nyog. yuav tsum tau xaiv raws li qhov tshwj xeeb laser tsis thiab kev siv ib puag ncig. Nyob rau tib lub sijhawm, cov cuab yeej tiv thaiv yuav tsum tau siv kom raug, xws li hnav cov tsom iav tshwj xeeb, tshwj xeeb laser tiv thaiv qhov rais rau cov khoom siv, thiab lwm yam, kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb.

A. Reflection Technology
Kev siv thev naus laus zis ntawm kev tiv thaiv laser feem ntau coats cov txheej txheem siab refractive index dielectric zaj duab xis nyob rau saum npoo ntawm cov khoom. Thaum lub teeb hits no dielectric zaj duab xis, txij li thaum tag nrho cov reflected lub teeb ntawm lub interface muaj tib theem, qhov no yuav ua rau lub teeb ntawm lub wavelength yuav tsum reflected. ntxiv dag zog. Qhov kev tiv thaiv zoo li no tuaj yeem tsis tsuas yog muaj kev cuam tshuam lub teeb laser los tiv thaiv lub qhov muag, tab sis kuj muaj peev xwm xa mus rau lwm lub teeb pom kev zoo.

Tsis tas li ntawd, muaj ib txoj kev tsim khoom uas tuaj yeem nqus tau lub teeb hauv qhov dav spectrum band thiab txo qhov kev xav ntawm cov khoom nto. Cov txheej txheem suav nrog muab cov khoom siv los kho nrog qhov roughness tsawg dua 0.1, thiab tom qab ntawd ua ob theem kev kho ntawm cov khoom siv. Laser ua cov ntaub ntawv periodic micron lug nyob rau hauv thawj theem, thiab tom qab ntawd cov ntaub ntawv periodic micro-nano lug nyob rau hauv lub thib ob theem.

Tsis tas li ntawd, rau kev tiv thaiv kev tiv thaiv ntawm high-zog lasers, ntau cov txheej txheem txheej txheem tam sim no tsuas yog siv los ua cov yeeb yaj kiab nyias ntawm cov khoom siv uas tiv taus hluav taws xob laser. Kev tshawb fawb ntawm cov khoom siv hluav taws xob muaj zog laser tiv thaiv raws li cov cuab yeej siv tshuaj plasma tseem tab tom ua tiav.

B. Absorption Technology
Kev nqus tshuab ntawm kev tiv thaiv laser feem ntau yog siv cov kev xaiv haum ntawm cov khoom nws tus kheej kom ua tiav cov kev xaiv nqus ntawm laser ntawm cov wavelengths tshwj xeeb kom ua tiav lub hom phiaj ntawm kev tiv thaiv. Qhov zoo ntawm cov thev naus laus zis no yog tias nws tsis cuam tshuam los ntawm qhov xwm txheej ntawm lub kaum sab xis ntawm lub laser, yog qhov tsim nyog rau cov duab kos duab nrog lub ntsej muag loj dua, thiab qhov saum npoo tsis yooj yim rau hnav. Txawm li cas los xij, absorbing zog tuaj yeem ua rau cov khoom puas tsuaj rau nws tus kheej.

Lub hauv paus ntsiab lus yog ntxiv lub teeb absorber ntawm ib lub wavelength tshwj xeeb rau cov khoom siv lens, thiab siv lub teeb pom kev zoo ntawm lub absorber kom nqus tau thiab tiv thaiv lub teeb ntawm cov wavelength sib thooj uas nws los rau hauv kev sib cuag nrog. Nws yog ib qho tsim nyog sau cia tias koj yuav tsum tsis txhob saib ncaj qha rau ntawm qhov chaw laser thaum hnav cov tsom iav tiv thaiv laser, thiab kev ruaj ntseg ntawm cov tsom iav laser tiv thaiv yuav tsum tau tswj lub teeb pom kev hauv 5 vib nas this.

C. Scattering Technology
Lub tshuab hluav taws xob ntawm kev tiv thaiv laser feem ntau yog siv qhov tshwm sim uas thaum lub teeb ntsib teeb meem los yog cov khoom thaum lub sij hawm nthuav tawm, nws yuav deviate los ntawm thawj propagation kev taw qhia. Qhov no deviation tshwm sim tuaj yeem txhim kho los ntawm kev nce qhov loj me, cov duab lossis kev faib tawm ntawm cov scatterers, yog li ua tiav kev tawg paj zoo thiab kev tiv thaiv ntawm lasers ntawm cov wavelengths tshwj xeeb.

Tshwj xeeb, optical limiting technology raws li nonlinear kho qhov muag cov hauv paus ntsiab lus yog tam sim no ib qho ntawm feem kev tshawb fawb thiab kev cog lus thev naus laus zis. Nws plays lub luag haujlwm tseem ceeb hauv kev siv hluav taws xob siab siv laser. Ntawm lawv, kev tiv thaiv thev naus laus zis raws li lub teeb pom kev tsis zoo ntawm cov pa roj carbon nanoparticle ncua kev kawm yog ib qho piv txwv. Los ntawm kev tswj cov concentration, particle loj thiab lwm yam tsis tau ntawm cov pa roj carbon nanoparticle ncua kev kawm ntawv, zoo scattering los ntawm laser teeb ntawm tej wavelengths yuav ua tau tiav.

Tsis tas li ntawd, kuj tseem muaj txoj hauv kev uas siv cov khoom siv kho qhov muag ntawm cov khoom nto kom ua tiav cov kev tiv thaiv laser, xws li laser tiv thaiv films npaj los ntawm cov ntaub ntawv nanostructured. Cov txheej no tuaj yeem ua tiav qhov nqus tau zoo ntawm lub teeb laser ntawm qhov tshwj xeeb wavelengths los ntawm qhov ua kom zoo dua Raman tawg.

D. Attenuation Technology

Lub tshuab thev naus laus zis ntawm kev tiv thaiv laser feem ntau txo qhov kev siv ntawm laser los ntawm kev nqus, tawg lossis kev xav, thiaj li ua tiav lub hom phiaj ntawm kev tiv thaiv. Tshwj xeeb, attenuated laser tiv thaiv tsom iav siv lub hauv paus ntsiab lus no los lo lo ntsiab muag nrog ib txheej ntawm cov khoom uas tuaj yeem nqus tau lub teeb ntawm cov wavelengths tshwj xeeb. Thaum cov teeb pom kev ntawm cov wavelengths tshwj xeeb ntaus lub lo ntsiab muag, lawv yuav nqus thiab thaiv lub teeb, yog li tiv thaiv lawv los ntawm kev nkag mus rau lub qhov muag thiab ua rau muaj kev puas tsuaj.

Tsis tas li ntawd, muaj kev tiv thaiv thev naus laus zis raws li cov qauv kev kho qhov muag tsis zoo xws li cov ntxaij lim dej hloov kho qhov muag, tsom rau tus kheej / tus kheej-defocusing limiters, thermal lens limiting, thiab lwm yam. Txhua txoj hauv kev thiab cov thev naus laus zis no muaj qhov zoo thiab qhov tsis zoo, thiab kev tiv thaiv tsim nyog. yuav raug xaiv raws li qhov tshwj xeeb laser tsis thiab kev siv ib puag ncig. Nyob rau tib lub sijhawm, cov khoom siv tiv thaiv, xws li hnav tsom iav tshwj xeeb, yuav tsum tau siv kom raug kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
