Kev hloov pauv cov kev lig kev caiLiNbO3 modulator
Tsis ntev los no, ib pab pawg tshawb fawb hauv Suav teb tau tshaj tawm daim ntawv pov thawj tsim khoom rau kev siv tshuab laser zaus xauv siv LiNbO3 modulator. Lub hauv paus ntawm daim ntawv pov thawj yog lub kaw lus tshiab PDH (Pound Driver Hall) laser zaus xauv uas tig rov qab cov txheej txheem ib txwm muaj.
1. Cov teeb meem ntawm cov thev naus laus zis ib txwm muaj:
Cov txheej txheem xauv zaus PDH ib txwm siv feem ntau siv lithium niobate (LiNbO3)electro-optic modulatorlos tsim cov optical sidebands uas xav tau. Txoj hauv kev no muaj peb qhov teeb meem tseem ceeb: tus nqi siab thiab cov qauv nyuaj (xav tau cov RF driver circuits nyuaj), kev nkag siab rau ib puag ncig (qhov kub thiab kev hloov pauv ntawm kev ntxhov siab tuaj yeem ua rau kev ua haujlwm tsis ruaj khov), thiab cov teebmeem amplitude modulation (RAM), uas tuaj yeem ua rau lub teeb liab xauv thiab cuam tshuam loj heev rau kev ruaj khov mus sij hawm ntev ntawm lub kaw lus.
2. Cov kev daws teeb meem tshiab:
Cov pab pawg tshawb fawb Suav tau tso tseg tag nrho cov khoom siv hluav taws xob-optic modulator ib txwm muaj. Lub hauv paus tseem ceeb ntawm kev tsim kho tshiab yog nyob rau hauv kev tsim qauv sib koom tes ntawm "semiconductor optical amplifier (SOA amplifier) ua ke nrog dual channel acousto-optic frequency shifter (AOM modulator)". Lub hauv paus ntsiab lus tshwj xeeb yog: tom qab faib cov noob laser beam, obAOM modulatorsiv rau kev hloov pauv zaus kom meej, thiab tom qab ntawd ob lub teeb ci no raug txhaj rau hauv SOA amplifier hauv lub xeev nce siab. Tsim kom muaj ntau lub teeb liab sab nraud uas xav tau rau PDH zaus xauv los ntawm kev siv cov teebmeem nonlinear xws li plaub nthwv dej sib xyaw (FWM) hauvSOA amplifier.
3. Cov txiaj ntsig ntawm kev ua tau zoo los ntawm:
Kev ruaj khov kawg: Cov khoom siv SOA (xws li cov ntawv ntim npauj npaim) tau koom ua ke nrog kev tswj kub thiab tsis muaj kev cuam tshuam rau kev cuam tshuam ib puag ncig, tshem tawm cov teebmeem RAM los ntawm lub cev thiab ua tiav qhov kev xauv ntev ntev ultra-high precision (zoo dua 5 × 10 ⁻¹¹ / hnub).
Qhov sib piv ntawm lub teeb liab thiab lub suab nrov: Los ntawm kev tswj hwm qhov hloov pauv zaus ntawm lub dual AOM modulator, nws muaj peev xwm ua tiav qhov sib phim meej ntawm qhov zaus ntawm sab thiab qhov ntau yam spectral dawb (FSR) ntawm qhov chaw siv, yog li txhim kho qhov sib piv ntawm lub teeb liab thiab lub suab nrov ntawm lub teeb liab yuam kev.
Txo nqi thiab me me: SOA amplifier tshem tawm cov khoom siv hluav taws xob kim thiab cov voj voog nyuaj, tsuas yog xav tau kev tsav tsheb tam sim no yooj yim xwb. Qhov no ua rau lub kaw lus me dua thiab pheej yig dua, uas yog qhov zoo rau kev ua tiav me me thiab kev siv tau ntawm cov khoom siv.
4. Cov kev cia siab ntawm daim ntawv thov thiab kev xav tau ntawm kev ua lag luam:
Cov thev naus laus zis no ua tau raws li qhov xav tau ntawm cov khoom siv laser ruaj khov heev hauv kev txhim kho thev naus laus zis quantum, thiab muaj kev cia siab dav dav, suav nrog:
Lub moos teeb uas teeb rau hauv qhov chaw thiab lub tsheb (yuav tsum tiv taus kev co hnyav).
Quantum gravimeter thiab cold atom interferometer (siv rau kev tshawb nrhiav geological thiab kev caij nkoj hauv qab dej).
Kev siv fiber optic sensing thiab LiDAR.
Hauv kev ua lag luam tam sim no, tshwj xeeb tshaj yog nyob rau hauv kev tshawb fawb txog kev tshawb fawb, kev lag luam tub rog, thiab kev lag luam aerospace, muaj kev nce ntxiv ntawm kev xav tau rau cov modules laser uas tswj tau ywj pheej, pheej yig, thiab ruaj khov heev los ntawm cov tuam txhab. Cov thev naus laus zis patented no ntes tau qhov sib txawv ntawm kev ua lag luam no.
