Kulamulira Kugawanika kwa Laser mu Ukadaulo wa Laser

Kulamulira Kugawanika kwa Lasermu Ukadaulo wa Laser
1, Tanthauzo Loyambira ndi Makhalidwe Abwino
Kulamulira kwa polarization ya laser ndi ukadaulo wapadera wowongolera malo owoneka bwino womwe umasintha, kusintha, kukhazikika, ndikuzindikira momwe mafunde a kuwala kwa laser alili. Mkhalidwe wa polarization wa laser umatanthauza njira ya kugwedezeka kwa vector yamagetsi, kuphatikiza polarization yolunjika, polarization yozungulira, ndi polarization yozungulira. Kusintha kwa polarization state, kukhazikika kwa polarization, ndi modulation ya polarization yothamanga kwambiri kumatha kuchitika kudzera mu ma waveplates, polarizers, ndi zida zosinthira magawo. Makhalidwe a polarization amakhudza mwachindunji kusintha kwa ma frequency osakhala a linear, modulation yolumikizirana ya optical, muyeso wa interferometric, ndi zotsatira za laser processing. Ndi gawo lofunikira kwambiri la machitidwe osiyanasiyana a laser olondola. Poyankha vuto la kutulutsa kosakhazikika kapena kosasinthika kwa polarization kwa ma laser ena,kulamulira kwa polarizationchipangizochi chimatha kusintha polarization iliyonse ya chochitika kukhala mkhalidwe wa polarization womwe ukufunidwa ndikusintha polarization mwachangu kwambiri, kukwaniritsa zosowa za machitidwe osiyanasiyana a modulation ndi interferometric.

2, mfundo zazikulu ndi kapangidwe ka dongosolo
Mfundo yeniyeni ya ukadaulo uwu imachokera pa kugawa kwa kuwala kochokera ku malo ozungulira mphamvu ya magetsi a mafunde a kuwala: ma polarizer amakwaniritsa kuwunikira kwa polarization, zomwe zimangolola kuwala kolumikizidwa molunjika mbali zinazake kuti kudutse; Ma Wave plates amadalira mphamvu ya birefringence ya ma crystals kuti abweretse kusiyana kwa magawo okhazikika ndikukwaniritsa kusintha kwa mitundu yosiyanasiyana ya polarization; Wowongolera polarization wamphamvu amasintha birefringence mwa kufinya ulusi wa kuwala ndi kristalo wa electro-optic, ndikusintha kusiyana kwa magawo nthawi yeniyeni kuti akwaniritse mkhalidwe wopitilira komanso wosinthika wa polarization. Ikhozanso kulipira birefringence yosasinthika yomwe imachitika chifukwa cha kusokonezeka kwa chilengedwe pakutumiza kwa ulusi wa kuwala ndikutseka mkhalidwe wa polarization yotuluka.
Dongosolo lonse lolamulira polarization la laser limapangidwa ndi polarizer/analyzer, phase delay waveplate, dynamic polarization controller, polarization detection module, ndi polarization feedback locking unit.

3, magawo ofunikira ndi gulu la zinthu
Magawo ake ofunikira ndi monga chiŵerengero cha kutha kwa polarization, kulondola kwa kuchedwa kwa gawo, liwiro la kuyankha kwa modulation, kuchuluka kwa mafunde ogwirira ntchito, ndi zina zotero. Chogulitsachi chingagawidwe m'magulu awiri: static polarization control, dynamic programmable polarization control, ndi polarization locking system malinga ndi modulation mode, free space polarization control ndi fiber type polarization control malinga ndi mtundu wa chipangizo, ndi polarization transformation,kusintha kwa polarization, kukhazikika kwa polarization, ndi kusanthula ndi kuzindikira polarization malinga ndi ntchitoyo.

4, Ubwino, kuipa ndi njira yopititsira patsogolo chitukuko
Ubwino waukulu wa ukadaulo uwu ndi monga kuthekera kokwaniritsa kusintha kwa polarization state, kuthandizira kusintha kwa polarization mwachangu, kuletsa kusuntha kwa optical path polarization, komanso kusinthasintha kwamphamvu kwa chipangizocho. Komabe, ilinso ndi zoletsa monga kulumikizana kwamphamvu kwa mafunde a mafunde, kuthekera kwa kutentha kwa birefringence m'malo amphamvu kwambiri, malire otsika a mphamvu ya optical pazida za fiber optic, ndi kusuntha kwa gawo komwe kumachitika chifukwa cha kusintha kwa kutentha. Pakadali pano, ukadaulo uwu wagwiritsidwa ntchito kwambiri pakulankhulana kwa fiber optic, machitidwe osalunjika a optic, interferometry yolondola, kukonza laser, kafukufuku wa quantum optics ndi zochitika zina. M'tsogolomu, idzapita ku zida zowononga kwambiri za broadband, ultra high speed electro-optical control, integrated photonic chip polarization control, intelligent closed-loop stability, komanso kuzindikira kwathunthu kwa polarization.
