Laser: Qhov txawv ntawm ib hom Laser thiab Multi-mode Laser

Lasersyog cov khoom siv uas siv lub hauv paus ntsiab lus ntawm kev txhawb zog hluav taws xob los ua kom nrov lossis oscillate lub teeb nyob rau hauv qee yam tshuaj lom neeg. Lasers kuj tau muab faib ua ib hom thiab ntau hom. Qhov tseem ceeb sib txawv ntawm ib hom lasers thiab multi-mode lasers yog tias tsuas muaj ib hom nyob rau hauv cov zis beam hom ntawm ib hom lasers, thaum muaj ntau hom nyob rau hauv cov zis beam hom ntawm multi-mode lasers.

Ib hom lasers tsim cov kab teeb pom kev zoo heev nrog tib hom kev hloov pauv (TEM00), uas txhais tau hais tias cov nqaj sib txawv me ntsis thaum lub sijhawm nthuav tawm, tuaj yeem ua kom pom tseeb me dua thiab ci dua, thiab tsim nyog rau kev siv nrog Cov kab hluav taws xob siab heev uas yuav tsum muaj xws li kev ntsuas qhov tseeb, kev phais kho mob, thiab khaws cov ntaub ntawv kho qhov muag.

Nyob rau hauv sib piv, multi-mode lasers tsim kab teeb uas muaj ntau hom transverse. Txawm hais tias lawv cov zis hluav taws xob feem ntau yog siab dua thiab tus nqi qis, cov nqaj zoo tsis zoo li ib hom lasers. Lawv tsim nyog rau cov ntawv thov uas tsis xav tau cov kab teeb pom kev zoo, xws li cov khoom siv, luam ntawv, thiab teeb pom kev loj loj. Feem ntau, kev xaiv ntawm ib hom lossis ntau hom lasers nyob ntawm cov kev cai tshwj xeeb ntawm cov nqaj zoo, lub zog tso zis, thiab tus nqi rau cov ntawv thov tshwj xeeb.

Ib hom laser yog ib qho tseem ceeb ntawm kev faib tawm hauv tshuab laser, nrog rau ntau yam ntawm cov yam ntxwv thiab kev siv.
1. Kev txhais ntawm ib hom laser
Lub tswv yim ntawm transverse hom (TEM00 hom): Lub laser beam generated los ntawm ib hom laser muaj qis tshaj-order transverse hom, uas yog lub TEM00 hom. Hom no tseem hu ua hom qauv lossis Gaussian hom. Nws nthuav tawm lub teeb siv hluav taws xob uas txo qis los ntawm qhov chaw mus rau sab nraud, kom cov nqaj sib txawv me ntsis thaum propagating nyob rau qhov ntev thiab tswj tau qhov siab ntawm qhov sib txuam.
Beam zoo (M2 yam): M2 yam yog qhov ntsuas ntsuas qhov zoo ntawm lub teeb laser. Nws piav txog qhov zoo sib txawv ntawm lub beam piv rau qhov zoo tshaj Gaussian beam. Vim nws yuav luag zoo meej Gaussian hom, M2 yam ntawm ib hom laser ib leeg yog ze rau 1, qhia tau hais tias tsis tshua muaj siab beam zoo.
2. Qhov zoo ntawm ib hom laser
High beam zoo: Vim nws cov qauv transverse zoo heev, ib hom lasers muab cov nqaj zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau muaj cov kab teeb zoo heev thiab cov teeb pom kev zoo.
Tsawg divergence lub kaum sab xis: Lub divergence lub kaum sab xis ntawm ib hom laser yog qhov me me, uas tso cai rau lub nqaj kom nyob twj ywm thaum xa mus rau qhov ntev, txo qhov teeb meem ntawm qhov chaw loj los ntawm kev ncua deb.
High brightness: Lub siab ci ntawm ib hom lasers ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau lub teeb ci siab, xws li precision txiav thiab precision vuam.
3. Daim ntawv thov ntawm ib hom lasers
Kev ntsuas qhov tseeb: Hauv kev ntsuas kev ntsuas uas yuav tsum tau muaj qhov raug siab heev, xws li ntsuas qhov deb thiab ntsuas ntsuas, ib hom lasers nyiam vim lawv qhov kev coj ua siab thiab qis beam divergence.
Kev phais kho mob: Hauv kev siv kho mob xws li phais kho qhov muag thiab kho tawv nqaij, ib hom lasers tau siv dav vim lawv cov kev tswj xyuas zoo thiab kev tswj xyuas lub zog.
Kev khaws cov ntaub ntawv kho qhov muag: Hauv qhov muag disc hlawv thiab cov ntaub ntawv khaws cia thev naus laus zis, kev siv ib hom lasers tuaj yeem txhim kho cov ntaub ntawv khaws cia ceev thiab kev nyeem ntawv raug.

Multimode lasers tau qhia lawv tus nqi tshwj xeeb thiab siv dav hauv ntau daim ntawv thov kev lag luam thiab kev lag luam.
1. Kev txhais ntawm multimode lasers
Ntau hom kev txiav txim siab dua: Tsis zoo li tib hom qauv (TEM00) tsim los ntawm ib hom lasers, multimode lasers tuaj yeem ua haujlwm hauv ntau hom transverse los tsim ntau hom ntawm lub teeb me ntsis, uas feem ntau suav nrog ntau lub teeb siv. peaks thiab tsim complex teeb pom kev qauv.
Beam zoo (ntau dua M2 yam): Hauv multimode lasers, vim muaj ntau hom kev hloov pauv, nws qhov M2 zoo tshaj yog siab dua li ntawm ib hom lasers, qhia tias cov nqaj zoo yog qis dua thiab lub divergence lub kaum sab xis loj dua, tab sis nws yog haum rau txawv daim ntawv thov scenarios.
2. Qhov zoo ntawm multimode lasers
Lub zog tso zis ntau dua: Multimode lasers feem ntau tuaj yeem muab lub zog tso zis ntau dua li ib hom lasers, uas ua rau lawv tsim nyog rau cov ntawv thov uas xav tau lub zog siab, xws li cov khoom siv ua haujlwm thiab thaj chaw loj irradiation.
Tus nqi-zoo: Piv nrog ib hom lasers, multimode lasers feem ntau pheej yig dua los tsim, ua rau lawv nrov dua hauv cov nqi siv tau.
Cov chaw thov dav dua: Vim lawv lub zog siab thiab tus nqi qis, multimode lasers tshwj xeeb tshaj yog nrov hauv kev tsim khoom, kev tshaj tawm thiab lwm yam lag luam uas xav tau cov kev daws teeb meem siab zog laser.
3. Kev siv ntau hom lasers
Kev ua cov khoom siv: Hauv kev ua cov khoom siv xws li hlau txiav, vuam thiab kho saum npoo, multimode lasers muab lub zog txaus los ua cov chaw loj lossis cov ntaub ntawv tuab.
Kev lag luam luam ntawv: Hauv laser luam ntawv thev naus laus zis, lub zog siab ntawm multimode lasers tuaj yeem ua tiav cov ntaub ntawv loj ntawm cov ntaub ntawv encoding thiab duab rendering.
Lub teeb pom kev loj hauv cheeb tsam: Hauv theem teeb pom kev zoo, teeb pom kev zoo vaj tsev, thiab kev ruaj ntseg thiab kev soj ntsuam daim ntawv thov, multimode lasers tau dav siv vim lawv cov hluav taws xob ntau dua kom ua tiav qhov ci ntsa iab thiab dav dav.

Thaum xaiv ib lub laser, nws yog ib qho tseem ceeb kom nkag siab txog cov yam ntxwv ntawm cov lasers sib txawv thiab lawv qhov chaw siv. Qhov no tsis yog tsuas yog xav txog cov kev qhia tshwj xeeb xwb, tab sis kuj tseem pom qhov kev txhim kho yav tom ntej.
1. Xaiv raws li daim ntawv thov
Kev lag luam tawm ntawm qhov tseeb thiab lub zog: Rau cov ntawv thov uas yuav tsum tau muaj qhov siab tshaj plaws (xws li kev ntsuas qhov tseeb lossis kev kho mob phais), ib hom lasers feem ntau yog thawj qhov kev xaiv vim lawv cov kab teeb pom kev zoo thiab lub kaum sab xis qis. Rau cov ntawv thov uas xav tau lub zog ntau dua (xws li kev ua cov khoom siv lossis cov teeb pom kev loj), ntau hom lasers yog qhov tsim nyog dua.
Kev txiav txim siab ntawm tus nqi thiab kev ua haujlwm: Ib hom lasers feem ntau kim dua, tab sis muab cov nqaj zoo dua; thaum multi-mode lasers muaj qhov zoo tshaj plaws hauv cov nqi-zoo, tshwj xeeb tshaj yog tsim rau kev lag luam loj. Cov neeg siv yuav tsum tau xaiv raws li kev siv nyiaj txiag thiab kev ua haujlwm.
2. Kev tsim kho thev naus laus zis
Kev txhim kho hauv ib hom laser tshuab: Nrog rau kev nce qib ntawm cov thev naus laus zis, ib hom lasers tau nce lub zog thaum tswj cov nqaj zoo, ua rau lawv siv ntau dua hauv cov teb yav dhau los los ntawm ntau hom lasers.
Ua kom muaj zog thiab txo cov nqi ntawm ntau hom lasers: Kev tsim kho thev naus laus zis kuj tseem ua rau kev txhim kho ntau hom lasers, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm kev ua kom muaj zog thiab txo cov nqi tsim khoom, uas ua rau lawv txaus nyiam nyob rau hauv ntau yam kev siv.

Thaum xaiv ib lub laser, nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai ntawm laser, xav txog cov kev xav tau sib txawv ntawm cov yam ntxwv ntawm laser xws li lub zog, qhov tseeb, thiab tus nqi rau cov kev xav tau sib txawv. Ib hom lasers yog tsim rau precision khiav hauj lwm xws li kev kho mob phais thiab precision ntsuas vim lawv zoo beam zoo thiab tsawg divergence kaum; thaum ntau hom lasers yog qhov tsim nyog rau kev siv xws li cov khoom siv thiab cov teeb pom kev loj hauv cheeb tsam vim lawv cov zis ntau zog thiab cov nqi siv tau zoo.

Raws li thev naus laus zis txuas ntxiv mus, qhov zoo ntawm ib hom thiab ntau hom lasers tau ntxiv dag zog ntxiv, uas tau maj mam nthuav lawv daim ntawv thov ntau yam. Piv txwv li, ib hom lasers tam sim no tuaj yeem muab lub zog ntau dua yam tsis tau poob cov kab zoo, thaum ntau hom lasers muaj zog ntxiv thaum txo nqi. Cov kev siv thev naus laus zis no tsis yog tsuas yog muab cov kev daws teeb meem zoo dua rau cov ntawv thov uas twb muaj lawm, tab sis kuj qhib rau thaj chaw thov tshiab.
