Hom Laser Modulators

Ua ntej, sab hauv kev hloov kho thiab sab nraud
Raws li cov txheeb ze sib txheeb ntawm tus modulator thiab laser, tusLaser tautuaj yeem muab faib ua kev hloov kho kev ua haujlwm thiab sab nraud.

01 Kev Ntsuas Sab Hauv
Cov teeb liab kev ntsuas yog nqa tawm hauv cov txheej txheem laser oscillation, yog li hloov pauv cov yam ntxwv ntawm lub laser tso tawm thiab ua kom tiav kev ua haujlwm.
(1) ncaj qha tswj lub laser twj tso rau kom ua tiav qhov kev tso tawm laser laser kev siv thiab seb muaj li ntawd nws tau tswj hwm los ntawm lub zog hluav taws xob.
(2) Cov kev hloov pauv tau muab tso rau hauv tus resonator, thiab kev hloov pauv ntawm lub teeb liab los tswj hwm cov kev tawm tsam, yog li hloov cov khoom tawm ntawm lub laser.

02 Kev Tawm Sab Nraud Sab Nraud
Kev hloov sab nraud yog qhov sib cais ntawm laser tiam thiab kev hloov kho. Yog hais txog kev thauj khoom ntawm cov teeb liab modulated tom qab tsim ntawm lub laser, uas yog muab tso rau hauv txoj kev kho kho kom nyob ntawm lub laser resonator.
Cov cim ntsuas hluav taws xob voltage yog ntxiv rau tus modulator los ua qee yam kev hloov pauv ntawm lub cev, thiab thaum lub teeb hla los ntawm kev hloov pauv, qee qhov kev hloov pauv, yog li nqa cov ntaub ntawv yuav kis tau. Yog li ntawd, kev hloov sab nraud tsis txhob hloov lub laser tsis, tab sis kom hloov pauv cov zis ntawm laser, xws li siv, ntau zaus, thiab lwm yam.

Thib ob,Laser Modulatorkev sib faib
Raws li cov ua haujlwm ua haujlwm ntawm tus modulator, nws tuaj yeem faib rau hauvElectro-Optic Hloov, AcoOttooptic kev hloov kho, Magicpingo-optic kev hloov kho thiab kev kho ncaj qha.

01 kev hloov kho ncaj qha
Tus tsav tsheb tam sim noSemiconductor laserlossis lub teeb-emitting diode yog modulated ncaj qha los ntawm lub teeb taws teeb liab, yog li cov zis tawm tau hloov kho nrog cov teeb liab hluav taws xob.

(1) TTL kev daws teeb meem hauv kev ua ncaj qha
Ib qho kev teeb liab ttl digital tau ntxiv rau lub teeb liab laser hluav taws xob, yog li ntawd lub teeb liab laser tam sim no tuaj yeem tswj hwm los ntawm cov paib sab nraud tuaj yeem tswj tau.

(2) Kev ntsuas kev sib tw hauv qhov ncaj qha
Ntxiv nrog rau lub teeb ci ntsa iab muab cov cim taw qhia (amplitude tsawg dua li 5V kev hloov pauv sab nraud sib sau mus rau lub laser sib txawv, thiab tom qab ntawd tswj cov zis laser fais fab.

02 Electro-optic kev kho mob
Kev siv cov nyhuv electro-outic yog hu ua electro-optic hloov. Lub cev ntawm lub cev ntawm electro-optic kev ua kom muaj cov khoom siv hluav taws xob, thiab thaum lub teeb hluav taws xob yuav hloov pauv, nws cov yam ntxwv kev kis tau yuav raug cuam tshuam thiab hloov pauv.

03 acoussto-optic kev hloov kho
Lub hauv paus ntawm lub cev ntawm acousto-optic kev hloov kho yog qhov tseeb ntawm lub teeb ci ntsa iab yog qhov tseeb ntawm lub teeb pom kev zoo nkauj lossis tawm los ntawm supernatural yoj thaum propagating nyob rau hauv nruab nrab. Thaum cov kev hloov pauv nruab nrab ntawm kev hloov pauv nruab nrab hauv nruab nrab, thiab kev coj ua ntawm lub teeb ci ntsa iab yuav tshwm sim thaum hloov pauv ntawm lub teb chaws supergenacer.
Acousto-optic kev hloov kho yog lub cev nqaij daim tawv uas siv cov nyhuv acoussto-optic kom thauj cov ntaub ntawv ntawm cov khoom siv kho tshiab zaus. Cov teeb liab modulated yog ua raws electro-acoustic transducer hauv daim ntawv ntawm hluav taws xob teeb liab), thiab cov teeb liab kev sib raug siv tau hloov mus rau hauv cov teb ultrasonic. Thaum lub teeb nthwv dej hla dhau ntawm cov acousto-optic nruab nrab, cov cab kuj kho qhov muag yog hloov kho thiab dhau los ua ib qho kev siv hluav taws xob uas "nqa".

04 Kev Tshaj Tawm Magneto-Kho Kho Mob
Magneto-optic kev hloov kho yog ib daim ntawv thov Faraday lub tshuab hluav taws xob lub tshuab hluav taws xob lub tshuab hluav taws xob. Thaum lub teeb vuag tshaj tawm los ntawm cov hlaueto-optical nruab nrab ntawm kev sib hloov ntawm lub dav hlau ntawm cov linearly polarized lub teeb yog hu ua sib nqus kev sib hloov.
Ib daim teb sib nqus yog siv rau hauv nruab nrab kom ua tiav kev sib nqus. Cov kev taw qhia ntawm Circuit Coatornetic teb yog nyob rau hauv cov kev taw qhia marcial ntawm qhov nruab nrab, thiab Faraday sib nraus yog nyob ntawm lub axial tam sim no sib nqus tam sim no sib nqus. Yog li no, los ntawm kev tswj hwm qhov tam sim no ntawm cov zaus high-zaus thiab hloov lub teeb ci ntsa iab, kom lub teeb hloov pauv nrog kev hloov pauv ntawm θ-θ kaum, thiaj li ua tiav kev hloov pauv.
