Kev faib tawm thiab Schememulation Schemulation ntawm Laser Modulator

Laser Modulatoryog ib hom tswj cov khoom siv laser laser, nws tsis yog qhov pib ua cov muaju, lo ntsiab muag thiab lwm yam, tsis yog ua ke raws li lasers,Cov Khoom Siv Laser, yog qib siab ntawm kev sib koom ua ke, hom thiab cov haujlwm ntawm cov khoom siv hauv chav kawm. Los ntawm cov nyom ntawm lub teeb, nws tuaj yeem pom tias qhov cuam tshuam rau lub teeb dej hiav txwv tuaj yeem hloov kho lub teeb, feem ntau ω thiab plaub yam sib piv, tus qauv laser modulator yog tusKev Siv Cov Qauv Kho, theem modulator, zaus shifter thiab deflector.

1. Siv cov khoom siv thiab cov khoom siv kho tshiab, nrog cov khoom siv kho qhov muag, cov khoom siv kho qhov muag, cov khoom siv hluav taws xob, cov suab nrov detenters, suab nrov omenatics, cov suab nrov omenators, suab nrov omenators, cov suab nrov omenatics, suab nrov omenatics, suab nrov omenators, cov suab nrov omenators, cov suab nrov omenatics, cov suab nrov omenators, cov suab nrov omenators, cov suab nrov omenators, cov suab nrov omenators, cov suab nrov omenators.

2. Theem Modulator: Siv los tswj cov theem ntawm nqaj, qhov nce ntxiv hu ua Lag, cov theem qis yog hu ua txhuas. Muaj ntau ntau yam kev hloov pauv theem, thiab lawv cov qauv ua haujlwm sib txawv, xws li theem kev siv ua kua me me, thiab lwm yam.

3. Zaus shifter: siv los hloov qhov zaus ntawm lub teeb pom kev, yog siv dav ua laser, nrog cov cuab yeej cuab tam, nrog Acoussto-Optical zaus shifter raws li tus neeg sawv cev raug.

4. Deflector: Siv los hloov cov kev taw qhia ntawm nqaj ntawm cov ntawv tshaj tawm, ntxiv rau qhov ntsuas hluav taws xob thiab cov ntsuas hluav taws xob thiab cov acousto-kho qhov muag.

Peb muaj cov tswvyim dav dav ntawm lub laser modulator, uas yog, cov khoom siv uas muaj kev tswj hwm ntawm laser modulator, tsuas yog ib tsab xov xwm yog qhov txaus los ntawm txaus. Yog li, ua ntej ntawm txhua yam, tsom rau kev siv cov qauv hloov kho. Kev siv modulator ua ib hom kev hloov kho dav hauv txhua hom kev siv kho mob, cov qauv siv tshuab hluav taws xob, cov qauv siv hluav taws xob, cov qauv siv hluav taws xob thiab cov kua siv lead ua kua.

1. Cov txheej txheem khomob: tshuab tas li los ntawm cov modulator yog qhov ntxov thiab feem ntau dav siv lub zog ntawm lub zog. Lub hauv paus ntsiab lus yog hloov qhov sib piv ntawm s teeb thiab p pom nyob rau hauv lub teeb polarized los ntawm kev sib hloov phaj, thiab faib lub teeb los ntawm polarizer. Los ntawm thawj phau ntawv hloov kho rau hnub no lub tshuab ua haujlwm siab thiab siab-precision, nws cov khoom lag luam tau raug ua tiav heev.

2.. Electro-optical cov phiaj xwm: Electro-optical siv cov qauv hloov kho, cov qauv yog raws cov pockels nyhuv ntawm electro-kho muaju. Lub xeev polarization ntawm tus nqaj polarized hloov pauv tom qab lub tshuab hluav taws xob nrog hluav taws xob tau thov, thiab tom qab ntawd cov polarization yog xaiv faib los ntawm polarizer. Kev siv ntawm lub teeb emitted tuaj yeem tswj tau los ntawm kev hloov cov kev siv hluav taws xob, thiab sawv / lub caij nplooj zeeg ntug ntawm NS qhov ntau tau tuaj yeem ncav cuag.

3. Acousto-optic cov phiaj xwm: acousto-optic modulator tseem siv tau los ua kev siv cov qauv hloov kho. Los ntawm kev hloov pauv qhov sib txawv, lub zog ntawm 0 lub teeb thiab 1 lub teeb tuaj yeem tswj tau kom ua tiav lub hom phiaj ntawm kev hloov kho lub teeb. Acoustooptic rooj vag (Optical HwjTuj) muaj cov yam ntxwv ntawm kev ceev nrawm thiab muaj kev puas tsuaj rau kev ua kom ceev.

4 Ua Kua Ua Kua Crystal Ntaus Feem ntau yog siv ua kua siv cov kua roj crystal, los ntawm kev thov kom muaj kua crystal los ntawm lub teeb loj los ntawm lub teeb, muaj cov yam ntxwv kev ntseeg siab.
