Cov yam ntxwv ntawm AOM acousto-optic modulator

Cov yam ntxwv ntawmAOM acousto-optic modulator

Tiv taus lub zog kho qhov muag siab

Lub AOM acousto-optic modulator tuaj yeem tiv taus lub zog laser muaj zog, kom ntseeg tau tias cov lasers muaj zog tuaj yeem hla dhau mus zoo. Hauv qhov txuas laser fiber tag nrho, qhovfiber acousto-optic modulatorhloov lub teeb tas mus li mus ua lub teeb pulsed. Vim yog lub voj voog ua haujlwm qis ntawm lub teeb optical pulse, feem ntau ntawm lub zog teeb nyob hauv lub teeb xoom. Lub teeb diffraction thawj zaug thiab lub teeb xoom sab nraum lub acousto-optic crystal kis mus rau hauv daim ntawv ntawm divergent Gaussian beams. Txawm hais tias lawv ua tau raws li cov xwm txheej sib cais nruj, ib feem ntawm lub zog teeb ntawm lub teeb xoom sib sau ua ke ntawm ntug ntawm lub optical fiber collimator thiab tsis tuaj yeem xa mus los ntawm lub optical fiber, thaum kawg hlawv los ntawm lub optical fiber collimator. Lub diaphragm qauv yog muab tso rau hauv txoj kev optical los ntawm lub thav duab kho kom raug rau-seem kom txwv tsis pub xa cov teeb diffracted ntawm qhov chaw ntawm lub collimator, thiab lub teeb xoom raug xa mus rau lub tsev kom tiv thaiv lub teeb xoom los ntawm kev hlawv lub optical fiber collimator.

Lub sijhawm nce sai

Hauv qhov txuas laser fiber ntau tag nrho, lub sijhawm nce ceev ntawm lub zog optical ntawm AOMacouste-optic modulatorua kom lub suab nrov ntawm lub cev muaj zog hla dhau mus tau zoo tshaj plaws, thaum tiv thaiv lub suab nrov hauv paus kom tsis txhob nkag mus rau hauv lub qhov rooj kaw suab acouste-optic (lub rooj vag pulse gate). Lub hauv paus tseem ceeb rau kev ua kom lub sijhawm nce sai ntawm cov suab nrov optical yog txo lub sijhawm hla ntawm cov nthwv dej ultrasonic los ntawm lub teeb ci. Cov txheej txheem tseem ceeb suav nrog kev txo qhov dav ntawm lub duav ntawm lub teeb ci lossis siv cov ntaub ntawv nrog lub suab nrov siab los tsim cov siv lead ua suab nrov.

Kev siv hluav taws xob tsawg thiab kev ntseeg siab siab

Cov dav hlau ya dav hlau muaj cov peev txheej tsawg, cov xwm txheej nyuaj thiab cov chaw nyuaj, uas ua rau muaj kev xav tau ntau dua rau kev siv hluav taws xob thiab kev ntseeg siab ntawm cov khoom siv fiber ntau optical AOM modulators. Cov fiber ntau opticalAOM modulatorsiv lub siv lead ua tangential acousto-optic tshwj xeeb, uas muaj qhov zoo acousto-optic M2. Yog li ntawd, nyob rau hauv tib qho kev ua haujlwm diffraction, qhov kev siv zog tsav tsheb uas xav tau yog tsawg. Lub optical fiber acoust-optic modulator siv lub zog qis no, uas tsis tsuas yog txo qhov kev xav tau rau kev siv zog tsav tsheb thiab txuag cov peev txheej tsawg hauv spacecraft, tab sis kuj txo qhov hluav taws xob electromagnetic ntawm lub teeb liab tsav tsheb thiab txo qhov kub dissipation siab ntawm lub kaw lus. Raws li cov txheej txheem txwv tsis pub (txwv) cov txheej txheem ntawm cov khoom spacecraft, txoj kev teeb tsa siv lead ua ib txwm ntawm optical fiber acousti-optic modulators tsuas yog siv cov txheej txheem sib txuas roj hmab silicone ib sab. Thaum cov roj hmab silicone tsis ua haujlwm, cov kev cai ntawm cov siv lead ua yuav hloov pauv nyob rau hauv cov xwm txheej kev co, uas tsis ua raws li cov txheej txheem ntawm cov khoom aerospace. Hauv qhov txuas laser, lub siv lead ua ntawm optical fiber acoust-optic modulator yog kho los ntawm kev sib txuas kho tshuab nrog silicone roj hmab sib txuas. Cov qauv teeb tsa ntawm cov nplaim sab saud thiab sab hauv qab yog qhov sib npaug li sai tau, thiab tib lub sijhawm, thaj chaw sib cuag ntawm qhov chaw siv lead ua thiab lub tsev teeb tsa tau ua kom siab tshaj plaws. Nws muaj qhov zoo ntawm lub peev xwm ua kom sov tau zoo thiab kev faib tawm qhov kub thiab txias sib npaug. Cov collimators ib txwm muaj tau kho los ntawm kev sib txuas roj hmab silicone. Nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias siab thiab kev co, lawv tuaj yeem hloov pauv, cuam tshuam rau kev ua haujlwm ntawm cov khoom. Cov qauv kho tshuab tam sim no tau txais yuav los kho cov khoom siv fiber ntau optical, uas ua rau cov khoom ruaj khov thiab ua tau raws li cov txheej txheem xav tau ntawm cov khoom siv aerospace.
