Dulmar guud oo ah afar modulator oo caadi ah

Waraaqdani waxay soo bandhigaysaa afar qaab oo beddelaad ah (oo beddelanaysa dhererka laser-ka ee nanosecond ama sucnanoosecoscond-ka domainka 'oo inta badan loo isticmaalo nidaamyada Fiber Laser. Kuwaas waxaa ka mid ah isbadal (acousto-optic optics), eom (isbadal elektro-optro ah), som /Soa(Moodhadka 'Semiconductor' waxaa sidoo kale loo yaqaanay modemonum moodhan, iyoHabsida tooska ah ee tooska ah. Iyaga dhexdooda, AOM,Eom, SOM waxay ka tirsan tahay modemanlanta dibedda, ama isbadal aan toos ahayn.

1. Acousto-optictic modulator (AOM)

Madaafiicda acousto-optic-ka waa geedi socod jireed oo adeegsada saameynta acousto-optic si ay u xiraan macluumaadka sifooriska indhaha. Markii la moodo, seenyaalaha korantada (modemitudedudedudedudel) ayaa marka hore lagu dabaqayaa korantada korantada ee korantada, kaas oo u beddelaya calaamadaha korantada ee garoonka ultrasonic. Markuu ifice mowjarka iftiinka dhex maro dhexdhexaadka acousto-optic, sidaha indhaha ayaa la beddelay oo uu noqdaa mid xoojiya mowqif mowduuc la beddelay oo sidda loo wado macluumaadka sababta oo ah tallaabada acoussto-optic

2. Qalabka elektaroonigga ah ee elektaroonigga ah(Eom)

Qaybiyaha elektro-optro-optectator waa atunator oo adeegsata saamaynta indhaha ee indhaha ee critstals-ka korantada indhaha, sida lithium nithate niticals (GITH03) iyo Critstalates-ka jilicsan (litta03). Saamaynta korantada ee elektro-indhaha ayaa ah marka korantada lagu dabaqayo crystal elektro-midab leh, oo ah isbedelka crystal-ka korantada ee elektro-scrout ee crystal, iyo is-dhexgalka, amnifulka, xoogga xoogga ee calaamadaha indhaha ayaa la xaqiijiyey.

Jaantuska: Qaab-dhismeedka caadiga ah ee wareegga wadaha ee EOM

3. Semiconductor Modulator / semiconductor Politifier ophical opical (som / Soa)

Semiconductor Comimol Comimelier (SOA) waxaa badanaa loo isticmaalaa arimaha cod-weyne ee indhaha, kaas oo leh faa'iidooyinka chip, isticmaalka awoodda, iwm.Erbium-Fopifier fiber). Cudurka 'semiconductor' podulator podulator-ka 'semiconductor' (som) waa aalad isku mid ah sida loo yaqaan 'semiconductor', laakiin sida loo adeegsado waxyar ayaa loo adeegsadaa sida loo isticmaalo markii loo isticmaalo maadada iftiinka ah ayaa waxyar ka duwan kuwa loo isticmaalo cod-weyne. Markii loo isticmaalo cod-weyne exchical exchical, wadista xasilloonida ee hadda jirta waxaa badanaa la siiyaa SoA si loo hubiyo in Soa ay ka shaqeyso gobolka toosan; Markii loo isticmaalo in lagu habeeyo in lagu habeeyo puls-ka indhaha, waxay soo saartaa calaamadaha indhaha ee joogtada ah ee SOA, waxay u isticmaashaa koronto koronto si ay u xakameyso wadaha Soa ee hadda jira, ka dibna waxay xakameeyaan gobolka Soa ee muxadiisha / elecinta. Isticmaalka astaamaha cod-aadlaha iyo astaamaha qaab-dhismeedka, habkan moodalka ayaa si tartiib tartiib ah loogu dabaqay codsiyada cusub, sida dareenka fiber-ka indhaha, lidka ama sawirrada caafimaadka iyo beeraha kale. Gaar ahaan duruufaha qaarkood ee u baahan mugga ugu sarreeya, isticmaalka korantada iyo saamiga baabi'inta.

4. Moodhka tooska ah ee laser sidoo kale wuxuu si toos ah u dhexgali karaa seenyaalaha indhaha ah ee si toos ah u xakameynaya laser ee aan caadi ahayn, sida ku cad shaxanka hoose, oo ah 3 nanasecond gullada wadnaha ah waxaa laga helaa iyada oo loo marayo moodalka tooska ah. Waxaa la arki karaa in ay jirto soo ifbaxaya bilowga garaaca wadnaha, kaas oo keena wax ku saabsan nasashada side-ka laser. Haddii aad rabto inaad qaadato garaaca wadnaha oo ku dhawaad ​​100 picosusvonds, waad isticmaali kartaa kabatadan. Laakiin sida caadiga ah ma rabno inaan helno soo-dhafkan.

Xisaab

AOM waxay ku habboon tahay wax soo saarka korantada indhaha dhowr watts oo leh shaqo isbadal badan. EOM waa soon, laakiin kakanaanta wadista ayaa aad u sarreysa oo saamiga baabi'inta ayaa hooseeya. Som (SOA) waa xalka ugu habboon ee GHZ xawaaraha iyo saamiga sare, oo leh isticmaalka awood hooseeya, is-miidaaminta iyo astaamaha kale. Diyaaradaha tooska ah ee tooska ah ee laser waa xalka ugu jaban, laakiin la soco isbeddelada ku yimaadda astaamaha muuqaalka. Nidaam kasta oo moodel ah wuxuu leeyahay faa'iidooyin iyo faa'iido-darrooyin u gaar ah, waana muhiim in si sax ah loo fahmo shuruudaha dalabka marka aad dooranayso qorshe, oo aad u yaqaanaan faa iidooyinka, oo aad u tawracayaan qorshayaasha ugu habboon. Tusaale ahaan, in loo qaybiyo farqiga fiber-ga, AOM-ga caadiga ah waa kan ugu weyn, laakiin qaab-dhismeedka nidaamka cusub, adeegsiga qorshayaasha Dhaqanka ee Liidar si loo yareeyo cabirka, yareynta cabirka, iyo in la wanaajiyo saamiga baabi'inta, nidaamka So Soa waa la qaatay. Nidaamka isgaarsiinta, nidaamka xawaaraha hooseeya ayaa sida caadiga ah qaadanaya nidaamka badalka tooska ah, nidaamka xawaaraha sarena wuxuu caadiyan adeegsadaa nidaamka beddelka sawirka indhaha.
