Dulmar guud ee naqshadaynta waddada indhaha
Qaab dadban oo xiran laba-mawjadaha-mawjadaha kala-baxa soliton resonant thulium-doped fiber laser oo ku salaysan qaab-dhismeedka muraayadda giraanta fiber-ka ee aan toos ahayn.
2. Sharaxaada jidka indhaha
Soliton-ka laba-mawjadaha-dhererka ah ee kala-baxa ayaa resonant thulium-dopedlaser fiberqaatay qaab-dhismeedka godka qaabdhismeedka qaabdhismeedka "8" (Jaantuska 1).
Qaybta bidix waa wareegga ugu weyn ee jiho-jiho ah, halka qaybta saxda ah ay tahay qaab-dhismeedka muraayadda fibre-ga ee aan toos ahayn. Wareegta aan jihayn ee bidixda ah waxa ka mid ah qaybiye xidhmo ah, 2.7m thulium-doped fiber optical (SM-TDF-10P130-HE), iyo 2 μm band fiber optic fiber-optical oo leh isku xidhka isku xidhka ee 90:10. Mid ka mid ah go'doon-ku-tiirsanaanta polarization (PDI), laba Kontaroolayaasha Polarization (Kontaroolayaasha Polarization: PC), 0.41m Fiber dayactir-dayactirka (PMF). Qaab dhismeedka muraayadda fibre optic-ga ee aan toos ahayn ee dhinaca midigta ah waxaa lagu gaaraa iyada oo la isku dhejiyo iftiinka ka soo baxa wareegga unidirectional ee bidix ilaa muraayadda fibre optic ee aan toos ahayn ee dhinaca midig iyada oo loo marayo qaab dhismeedka 2 × 2 isku-xiraha indhaha oo leh isku-dhafan 90:10. Qaab dhismeedka muraayadda muraayadda fibre-ga ee aan toos ahayn ee dhinaca midig waxaa ka mid ah 75-mitir fiber fiber optic ah (SMF-28e) iyo kontaroolaha polarization. Fiber indhaha oo 75-mitir ah oo hal-hab ah ayaa loo isticmaalaa si kor loogu qaado saamaynta aan tooska ahayn. Halkan, 90:10 isku-xidhaha fiber indhaha ayaa la shaqaaleysiiyay si loo kordhiyo faraqa wejiga aan tooska ahayn ee u dhexeeya faafinta saacadda iyo ka soo horjeeda. Wadarta dhererka qaabkan laba-mawjadaha dhererka ah waa 89.5 mitir. Habayntan tijaabada ah, nalka bamka ayaa marka hore soo mara isku-darka biamka si uu u gaadho faa'iidada dhexdhexaadka ah ee thulium-doped fiber optical. Ka dib thulium-doped fiber optical, 90:10 lammaane ayaa ku xiran si uu u wareego 90% tamarta gudaha daloolka oo u diro 10% tamarta ka soo baxa godka. Isla mar ahaantaana, filtariyaha Lyot ee birefringent waxa uu ka kooban yahay fibre-gaab-ilaalin-ilaaliye oo ku yaalla inta u dhaxaysa laba kontaroolayaasha polarization iyo polarizer, kaas oo door ka ciyaara shaandhaynta hirarka hirarka.
3. Aqoonta asalka ah
Waqtigan xaadirka ah, waxaa jira laba hab oo aasaasi ah oo lagu kordhinayo tamarta garaaca wadnaha ee lasers-ka. Mid ka mid ah habka ayaa ah in si toos ah loo yareeyo saameynta aan tooska ahayn, oo ay ku jiraan hoos u dhigista awoodda ugu sarreysa ee garaaca wadnaha iyada oo loo marayo habab kala duwan, sida isticmaalka maaraynta kala firdhinta ee garaaca wadnaha, oscillators Giant chirped, iyo laser-ka-baxa pulsed, iwm. Hab kale ayaa ah in la raadiyo habab cusub oo u dulqaadan kara isugeynta wejiga badan ee aan tooska ahayn, sida isku ekaanshaha iyo isku ekaanshaha. Habka kor ku xusan wuxuu si guul leh u kordhin karaa tamarta garaaca wadnaha eelaser garaacailaa tobanaan nanojoules. Resonance soliton dissipative (Dissipative soliton resonance: DSR) waa qaab samaynta kicinta leydi-geeska ah marka hore waxaa soo jeediyay N. Akhmediev et al. 2008. Sifada garaaca garaaca resonance soliton dissipative waa in, iyadoo la ilaalinayo baaxadda joogtada ah, ballaca garaaca garaaca iyo tamarta garaaca garaaca wadnaha ee aan mawjada kala qaybsanaan kordho monotonically kororka awoodda bamka. Tani, ilaa xad, waxay jebisaa xaddidaadda aragtida soliton-dhaqameedka ee tamarta hal-wadareedka. Resonance soliton dissipative waxaa lagu gaari karaa iyadoo la dhisayo nuugista qoyan iyo rogida nuugista buuxda, sida saameynta wareegtada polarization-ka ee aan tooska ahayn (NPR) iyo saamaynta muraayadda giraanta fiber-ka ee aan tooska ahayn (NOLM). Inta badan warbixinnada ku saabsan jiilka garaaca garaaca dhawaaqa soliton ee kala daadsan waxay ku saleysan yihiin labadan hab-qaab-quful.
