"Polarization" waa astaamo caadi ah oo ay leeyihiin laysarka kala duwan, kaas oo lagu go'aamiyo mabda'a sameynta laysarka.laambadda laysarkawaxaa soo saara shucaaca kiciya ee walxaha dhexdhexaadka ah ee iftiinka soo saaraya gudahalaysarShucaaca kiciya wuxuu leeyahay astaamo cajiib ah: marka photon dibadeed uu ku dhaco walxo ku jira xaalad tamar sare, walxaha ayaa shucaaca photon wuxuuna u gudbaa xaalad tamar hoose. Fotoonnada lagu soo saaro habkan waxay leeyihiin isla marxaladda, jihada faafinta iyo xaaladda polarization sida fototoonnada shisheeye. Marka durdurka photon lagu sameeyo laysarka, dhammaan fototoonnada ku jira durdurka photon-ka qaabka waxay wadaagaan isla marxaladda, jihada faafinta, iyo xaaladda polarization-ka. Sidaa darteed, habka dheer ee laysarka (soo noqnoqoshada) waa in la polarized.
Dhammaan laysarka ma aha kuwo kala qaybsan. Xaaladda kala qaybsanaan ee laysarka waxaa saameeya dhowr arrimood, oo ay ku jiraan:
1. Milicsiga resonator-ka: Si loo hubiyo in photons badan ay ku yaalliin meel gaar ah si ay u sameeyaan gariirro deggan oo ku jira godka oo ay u soo saaraannalka laysarka, wejiga ugu dambeeya ee resonator-ka waxaa badanaa lagu dahaadhaa filim milicsi oo la xoojiyay. Sida waafaqsan sharciga Fresnel, ficilka filimka milicsiga badan wuxuu sababaa in iftiinka ugu dambeeya ee milicsiga uu ka beddelo iftiinka dabiiciga ah una beddelo mid toosan.iftiin kala qaybsan.
2. Astaamaha habka faa'iidada: jiilka laysarka wuxuu ku salaysan yahay shucaaca kiciya. Marka atamka kacsan uu ku faafo fotonada hoos yimaada kicinta fotonada shisheeye, fotonadani waxay ku gariiraan jihada isku midka ah (xaaladda polarization) sida fotonada shisheeye, taasoo u oggolaanaysa laysarka inuu ilaaliyo xaalad polarization oo deggan oo gaar ah. Xitaa isbeddellada yaryar ee xaaladda polarization waxaa sifeeyn doona resonator-ka sababtoo ah oscillations xasilloon lama samayn karo.
Habka wax soo saarka laysarka dhabta ah, saxanka hirarka iyo kiristaalka polarization-ka ayaa badanaa lagu daraa gudaha laysarka si loo hagaajiyo xaaladda xasilloonida ee resonator-ka, si xaaladda polarization-ka ee godka uu u noqdo mid gaar ah. Tani ma aha oo kaliya inay ka dhigto tamarta laysarka mid aad u xoog badan, waxtarka kicinta ayaa sarreeya, laakiin sidoo kale waxay ka hortagtaa khasaaraha ka dhasha awood la'aanta in la ruxmo. Sidaa darteed, xaaladda polarization-ka ee laysarka waxay ku xiran tahay arrimo badan sida qaab-dhismeedka resonator-ka, dabeecadda dhexdhexaadka faa'iidada iyo xaaladaha oscillation-ka, mana aha mid had iyo jeer gaar ah.
