Incamake yuburyo bwiza bwo gushushanya

Uburyo bwa passiyo bwafunzwe bubiri-bwumurambararo ukwirakwiza soliton resonant thulium-dope fibre laser ishingiye kumiterere yindorerwamo ya fibre idafite umurongo.

2. Ibisobanuro byiza byinzira

Uburebure-bubiri-butandukanya soliton resonant thulium-ikopowelaserifata igishushanyo mbonera cya “8 ″ gifite imiterere yububiko (Ishusho 1).

Igice cyibumoso nigice nyamukuru kidafite icyerekezo, mugihe igice cyiburyo ari umurongo utari mwiza wa fibre fibre indorerwamo. Umuzenguruko w’ibumoso uterekejweho uruzitiro rurimo bundle itandukanya, fibre optique ya tulium 2,7m (SM-TDF-10P130-HE), hamwe na 2 μm band optique fibre fibre hamwe na coefficient ya 90:10. Isolator imwe iterwa na polarisiyasi (PDI), Igenzura rya Polarisiyasi ebyiri (Igenzura rya Polarisation: PC), 0.41m Fibre-kubungabunga Fibre (PMF). Imiterere idafite indorerwamo ya fibre optique yimpeta iburyo igerwaho muguhuza urumuri kuva ibumoso buterekejwe kumurongo hamwe nindorerwamo ya fibre optique ya fibre optique iburyo unyuze kuri 2 × 2 imiterere ya optique hamwe na coefficient ya 90:10. Imiterere y'indorerwamo idafite umurongo wa optique fibre iburyo irimo fibre optique ya metero 75 z'uburebure (SMF-28e) hamwe nu mugenzuzi wa polarisiyasi. Metero 75 ya fibre optique fibre ikoreshwa mugutezimbere ingaruka zitari kumurongo. Hano, fibre optique ya 90:10 ikoreshwa kugirango yongere itandukaniro ryumurongo utandukanijwe hagati yisaha nisaha yo gukwirakwiza amasaha. Uburebure bwuzuye bwubu buryo bubiri-burebure ni metero 89.5. Muri ubu buryo bwo kugerageza, urumuri rwa pompe rubanza kunyura mumashanyarazi kugirango rugere kunguka fibre optique ya fibre optique. Nyuma ya fibre optique ya thulium, ihuza 90:10 ihuza guhuza 90% yingufu ziri mu cyuho no kohereza 10% yingufu ziva mu cyuho. Muri icyo gihe, akayunguruzo ka Lyot kagizwe na fibre optique ya fibre optique iri hagati yubugenzuzi bubiri bwa polarisiyasi na polarizer, igira uruhare mukuyungurura uburebure bwumurongo.

3. Ubumenyi bwibanze

Kugeza ubu, hari uburyo bubiri bwibanze bwo kongera ingufu za pulse ya laseri. Uburyo bumwe ni ukugabanya mu buryo butaziguye ingaruka zidafite umurongo, harimo kugabanya imbaraga zimpiswi zinyuze muburyo butandukanye, nko gukoresha imiyoborere yo gukwirakwiza impiswi irambuye, oscillator nini nini, hamwe na laseri igabanya ibiti, nibindi. Uburyo bwavuzwe haruguru burashobora kongera imbaraga za pulse yalaserkugeza kuri nanojoules. Dissipative soliton resonance (Dissipative soliton resonance: DSR) ni uburyo bwo gushiraho impagarike y'urukiramende rwasabwe bwa mbere na N. Akhmediev n'abandi. muri 2008. Ikiranga impanuka ya soliton resonance pulses ni uko, mugihe ukomeje amplitude ihoraho, ubugari bwimpiswi nimbaraga zumurambararo utagabanije urukiramende rwiyongera rwonyine hamwe no kongera ingufu za pompe. Ibi, kurwego runaka, bicamo imbogamizi yimyumvire gakondo ya soliton kumbaraga imwe. Dissipative soliton resonance irashobora kugerwaho mukubaka ibyuzuye byuzuye hamwe no kwuzuza kwuzuye, nkibintu bitagira umurongo bya polarisiyonike (NPR) hamwe ningaruka zindorerwamo ya fibre idafite umurongo (NOLM). Raporo nyinshi kubyerekeranye no kubyara soliton resonance pulses ishingiye kuri ubwo buryo bubiri bwo gufunga.
