Kev Tswj Xyuas Kev Ua Phem Laserhauv Kev Siv Tshuab Laser
1、 Cov Lus Txhais Tseem Ceeb thiab Cov Txiaj Ntsig Tseem Ceeb
Kev tswj hwm polarization ntawm laser yog ib qho thev naus laus zis tswj hwm qhov chaw pom kev tshwj xeeb uas hloov kho, hloov pauv, ruaj khov, thiab ntes tau lub xeev polarization ntawm cov teeb laser. Lub xeev polarization ntawm laser hais txog kev coj ntawm lub zog hluav taws xob vector vibration, suav nrog linear polarization, circular polarization, thiab elliptical polarization. Kev hloov pauv ntawm lub xeev polarization, kev ruaj khov polarization, thiab kev hloov pauv polarization ceev ceev tuaj yeem ua tiav los ntawm waveplates, polarizers, thiab cov khoom siv hloov kho theem. Cov yam ntxwv polarization cuam tshuam ncaj qha rau kev hloov pauv zaus nonlinear, kev sib txuas lus optical modulation, kev ntsuas interferometric, thiab cov teebmeem ua laser. Nws yog ib chav ua haujlwm tseem ceeb ntawm ntau yam kev ua haujlwm laser precision. Hauv kev teb rau qhov teeb meem ntawm cov zis polarization tsis ruaj khov lossis random ntawm qee lub lasers, lubkev tswj hwm polarizationChav tsev tuaj yeem hloov txhua qhov xwm txheej polarization mus rau lub xeev polarization lub hom phiaj thiab dynamically hloov polarization ntawm kev kub ceev, ua tau raws li qhov xav tau ntawm ntau yam modulation thiab interferometric systems.
2. Cov ntsiab cai tseem ceeb thiab cov qauv ntawm lub kaw lus
Lub hauv paus ntsiab lus ntawm cov thev naus laus zis no yog raws li kev sib hloov ntawm lub teeb uas los ntawm qhov kev co ntawm lub teeb hluav taws xob nthwv dej: cov polarizers ua tiav kev tshuaj ntsuam polarization, tso cai rau tsuas yog lub teeb polarized linearly hauv cov lus qhia tshwj xeeb kom dhau los; Cov phaj nthwv dej vam khom cov nyhuv birefringence ntawm cov siv lead ua kom qhia txog qhov sib txawv ntawm theem ruaj khov thiab ua tiav kev hloov pauv ntawm cov xeev polarization sib txawv; Lub tshuab tswj hwm polarization dynamic kho qhov birefringence los ntawm kev nias lub fiber ntau optical thiab electro-optic siv lead ua, thiab kho qhov sib txawv ntawm theem hauv lub sijhawm tiag tiag kom ua tiav lub xeev polarization txuas ntxiv thiab hloov kho tau. Nws kuj tseem tuaj yeem them rau qhov birefringence random tshwm sim los ntawm kev cuam tshuam ib puag ncig hauv kev sib kis fiber ntau optical thiab xauv lub xeev polarization tso zis.
Lub kaw lus tswj polarization laser tag nrho muaj lub polarizer/analyzer, lub phaj waveplate qeeb, lub tswj polarization dynamic, lub module nrhiav polarization, thiab lub chav tswj polarization feedback.
3, Cov yam tseem ceeb thiab kev faib tawm khoom
Nws cov ntsiab lus tseem ceeb suav nrog qhov piv txwv polarization extinction, theem qeeb qhov tseeb, modulation teb ceev, ua haujlwm wavelength ntau yam, thiab lwm yam. Cov khoom tuaj yeem muab faib ua static polarization tswj, dynamic programmable polarization tswj, thiab polarization locking system raws li hom modulation, free space polarization tswj thiab fiber hom polarization tswj raws li hom ntaus ntawv, thiab polarization hloov pauv,kev hloov pauv polarization, kev ruaj khov ntawm polarization, thiab kev tshuaj xyuas polarization thiab kev tshawb pom raws li kev ua haujlwm.
4, Cov txiaj ntsig, qhov tsis zoo thiab kev coj ua ntawm kev loj hlob
Cov txiaj ntsig tseem ceeb ntawm cov thev naus laus zis no suav nrog lub peev xwm los ua tiav qhov kev hloov pauv polarization random, kev txhawb nqa rau kev hloov pauv polarization ceev ceev, kev tswj hwm ntawm txoj kev optical polarization drift, thiab kev hloov pauv modular muaj zog ntawm lub cuab yeej. Txawm li cas los xij, nws kuj muaj cov kev txwv xws li kev sib raug zoo ntawm wavelength ntawm cov phaj polarizers, kev cuam tshuam rau thermal birefringence hauv cov xwm txheej muaj zog siab, qhov txwv qis ntawm lub zog optical rau cov khoom siv fiber optic, thiab theem drift los ntawm kev hloov pauv kub. Tam sim no, cov thev naus laus zis no tau siv dav hauv kev sib txuas lus fiber optic, nonlinear optical systems, precision interferometry, laser processing, quantum optics kev tshawb fawb thiab lwm yam xwm txheej. Yav tom ntej, nws yuav tsim mus rau wideband siab puas tsuaj threshold cov khoom siv, ultra high speed electro-optical tswj, kev sib xyaw photonic chip polarization tswj, kev ruaj khov kaw-loop ntse, thiab kev sib xyaw ua ke polarization nrhiav.
