Uyilo lwe-1018nm Fiber Laser

Uyilo lweI-Laser yeFayibha ye-1018nm
I-laser yefayibha ye-1018nm isetyenziswa rhoqo njengomthombo wepompo ye-laser yefayibha ye-ytterbium enamandla aphezulu e-cascaded. Kwiskimu sokumpompa ngqo, i-976nmi-laser ye-semiconductorisetyenziswa ngokubanzi njengomthombo wepompo. Ukuze kufezekiswe amandla aphezulu e-ytterbium doped fiber lasers, ukwandisa amandla omthombo wokukhanya wepompo yindlela ebalulekileyo. Nangona kunjalo, i-1018nmi-laser yefayibhaithintelwe yimpembelelo yokukhupha okuzenzekelayo eyandisiweyo, kwaye amandla okukhupha kube nzima ukuwanyusa kakhulu. Abaphandi bafikelele kwi-2kw level 1018nm fiber laser ngokuphucula uyilo lweeparameter.
1. Uhlalutyo lwethiyori kunye noyilo
Umzobo wesicwangciso sendlela yovavanyo lwe-optical uboniswe ngezantsi. Umthombo wepompo usebenzisa i-976nm wavelength locked semiconductor laser WS-LD. I-WS-LD nganye inokubonelela malunga ne-250W yamandla epompo, adityaniswe kwi-resonator ye-ytterbium doped fiber nge-combiner. Yonke inkqubo isebenzisa i-bidirectional cascade pumping scheme. Ngokusetyenziswa kokubala kwethiyori kunye nokulinganisa, iiparameter ezifanelekileyo ze-ytterbium doped fiber (YDF) kunye ne-fiber Bragg grating (FBG) zahlalutywa ngokunzulu, kwaye imithetho yokwahluka kweempawu zemveliso ezifana namandla okukhupha i-laser, ukusebenza kakuhle kokuguqulwa kwe-optical ukuya kwi-optical, kunye ne-ASE suppression ratio (SAR) yafunyanwa, kwaye ixabiso elifanelekileyo leeparameter lamiselwa.

Okokuqala, ubudlelwane phakathi kweempawu zokuphuma kwelaser kunye nobude befayibha efakwe i-ytterbium, i-coefficient yokufunxwa kokukhanya kwepompo, kunye namaxabiso anxulumene namanani afunekayo buyabalwa; Okwesibini, ubudlelwane phakathi kweempawu zokuphuma kwelaser kunye nobude befayibha efakwe i-ytterbium, i-output coupling grating OC-FBG reflectivity, kunye nokubalwa kwamaxabiso afanelekileyo; Okokugqibela, ubudlelwane phakathi kobubanzi be-fiber winding, ukusebenza kakuhle kokuguqulwa, kunye nokusasazwa kwentsimi ye-optical output kuyaxoxwa, kwaye amaxabiso afanelekileyo eenombolo ayabalwa.
2. Isiphumo
Isicwangciso sokugqibela sikhethe i-YDF ye-2.6m kunye ne-grating reflectivity ye-99.5% kunye ne-20%, ngokwahlukeneyo. Ububanzi be-fiber winding yi-8cm. Amandla epompo angaphambili nangasemva yi-1500W kunye ne-1040W, ngokwahlukeneyo, kunye namandla okukhupha ayi-1940W kunye nokusebenza kokuguqula ukukhanya ukuya ekukhanyeni kwe-76.38%. Kwangaxeshanye, abaphandi bafumanise nesiphumo sokungazinzi semodi ye-TMI kwiimvavanyo ezisebenzayo, kwaye bonyusa umda we-TMI ngokunciphisa ububanzi be-winding ukuze kuthintelwe isiphumo se-TMI.
