Sarrafa Rarraba Laser a Fasahar Laser

Kula da Rarraba Lasera Fasahar Laser
1, Ma'anar Asali da Ƙimar Asali
Kula da rarrabawar Laser wata fasaha ce ta musamman ta sarrafa filin gani wadda ke daidaita, canzawa, daidaita, da kuma gano yanayin rabuwar raƙuman hasken laser. Yanayin rabuwar Laser yana nufin alkiblar girgizar vector na filin lantarki, gami da rabuwar layi, rabuwar zagaye, da rabuwar elliptical. Ana iya cimma sauyawar yanayin rabuwar, kwanciyar hankali na rabuwar, da daidaitawar rabuwar sauri ta hanyar faranti, polarizers, da na'urorin daidaitawar lokaci. Halayen rabuwar kai tsaye suna shafar juyawar mita mara layi, daidaitawar sadarwa ta gani, auna interferometric, da tasirin sarrafa laser. Sashe ne mai mahimmanci na aiki na tsarin laser daidaitacce daban-daban. Dangane da matsalar fitowar rabuwar mara kyau ko bazuwar wasu lasers,sarrafa rarrabuwar kawunaNaúrar na iya canza duk wani lamari na polarization zuwa yanayin polarization da aka yi niyya kuma tana canza polarization da sauri a babban gudu, tana biyan buƙatun tsarin daidaitawa daban-daban da tsarin interferometric.

2, Ka'idojin asali da tsarin da aka haɗa
Ka'idar zahiri ta wannan fasaha ta dogara ne akan rarrabuwar haske da ta samo asali daga yanayin girgizar sararin samaniya na filin lantarki na hasken: masu watsa haske suna cimma tantancewar rabuwar haske, suna ba da damar haske mai layi ɗaya kawai a takamaiman kwatance ya ratsa; Faranti masu watsawa sun dogara da tasirin walƙiya na lu'ulu'u don gabatar da bambancin lokaci mai ɗorewa da cimma canjin yanayin rabuwar haske daban-daban; Mai sarrafa watsa haske mai ƙarfi yana daidaita walƙiya ta hanyar matse zaren gani da lu'ulu'u na lantarki, kuma yana daidaita bambancin lokaci a ainihin lokaci don cimma yanayin rabuwar haske mai ɗorewa da daidaitawa. Hakanan yana iya ramawa ga raguwar walƙiya da bazuwar da rikice-rikicen muhalli suka haifar a cikin watsawar zaren gani da kuma kulle yanayin watsa haske.
Cikakken tsarin kula da polarization na laser ya ƙunshi polarizer/analyzer, farantin jinkiri na lokaci, mai sarrafa polarization mai ƙarfi, tsarin gano polarization, da kuma sashin kulle martanin polarization.

3, Maɓallan mahimmanci da rarrabuwar samfura
Babban maɓallan maɓallansa sun haɗa da rabon karewa na polarization, daidaiton jinkirin lokaci, saurin amsawar daidaitawa, kewayon tsawon aiki, da sauransu. Ana iya raba samfurin zuwa tsarin sarrafa polarization mai tsauri, tsarin sarrafa polarization mai ɗorewa, da tsarin kulle polarization bisa ga yanayin daidaitawa, sarrafa polarization na sarari kyauta da sarrafa polarization na nau'in fiber bisa ga nau'in na'urar, da kuma canjin polarization,daidaita rarrabuwar kawuna, kwanciyar hankali na polarization, da kuma nazarin polarization da ganowa bisa ga aikin.

4, Fa'idodi, rashin amfani da kuma alkiblar ci gaba
Babban fa'idodin wannan fasaha sun haɗa da ikon cimma canjin yanayin polarization ba tare da wani sharaɗi ba, tallafi ga sauya polarization mai sauri, danne karkatar da karkatarwar polarization ta hanyar gani, da kuma ƙarfin daidaitawa mai ƙarfi na na'urar. Duk da haka, tana da iyakoki kamar haɗin gwiwa mai ƙarfi na polarizers na farantin raƙuman ruwa, sauƙin kamuwa da birefringence na zafi a cikin yanayin wutar lantarki mai ƙarfi, ƙarancin iyaka na sama na ƙarfin gani don na'urorin fiber optic, da kuma karkatarwar lokaci wanda canje-canjen zafin jiki ke haifarwa. A halin yanzu, ana amfani da wannan fasaha sosai a cikin sadarwa ta fiber optic, tsarin gani mara layi, daidaitaccen interferometry, sarrafa laser, binciken kwantum optics da sauran yanayi. A nan gaba, za ta haɓaka zuwa ga na'urori masu girman baki masu girman baki, sarrafa electro-optical mai sauri, sarrafa polarization na guntu na photonic, kwanciyar hankali mai rufewa, da kuma gano cikakken polarization.
