Kwiminyaka elishumi edlulileyo, ngokuphuculwa okuqhubekayo komthombo wempompo kunye nesakhiwo se-laser, iteknoloji ye-fiber laser iphuculwe kakhulu. Ngokusekelwe kwifayibha ye-optical ene-doped (YDF-Laser) isetyenziswa kakhulu kwimizi-mveliso, uphando lwezenzululwazi, njl.njl. ngenxa yoguqulo lombane oluphezulu, umgangatho ongcono we-beam kunye nokuzinza.
Isazobe soku1. Isantya sokufunxa iSpectral sezinto ezahlukeneyo zetsimbi
Namhlanje-amandla aphezulu-imowudi ye-laser ifayibha kudala bakwazi ukuphumeza ngokulula imveliso yedijithali KW-level optical amandla, nto leyo eyenza lasers entsimini ukusetyenzwa kwesinyithi. Ngaphantsi kweemeko zamandla okukhanya okufanayo, ngenxa yezinga lokufunxa elahlukileyo, i-1 micron fiber laser esekelwe kwifiber yabantu abadala iphuculwe kakhulu xa i-CO2 laser ye-microns eyi-10 isebenza ngakumbi kunempahla yensimbi. Umzobo we-1 unika isantya sokufunxa okubonakalayo kwezinto ezahlukeneyo zetsimbi, ezinokubonwa kumfanekiso wokuba uninzi lwezinto zetsimbi kwiimpawu zokufunxa ze-spectrum zibonisa utyekelo lokuncipha njengoko ukwanda kwamaza optical kunyuka. Izinto zetsimbi ngokucacileyo zinamandla kunobude obuphumayo obumalunga ne-1070 nm xa kuthelekiswa nobude bendawo ye-CO2 laser kwi-CO2 laser kwi-10.6um. Ngokukodwa, izinga lokufunxa kwentsimbi phantsi kwe-1070 nm wavelength liphantse libe ngama-6 ngaphantsi kweemeko ze-10.6um zamaza.
Umzobo 2. Ukufunxwa okunxulumene ne-aluminosilicate kunye ne-phosphosilicate (YB) ifayibha kwi-800-1100 nm spectrum
Ngenxa yokuba ifayibha yamehlo edityanisiweyo inophawu lokufunxa olomeleleyo lwe-976 nm kunye ne-915 nm wavelength, ezo lasers ikakhulu zimpontshwa yi-semiconductor laser (LD) ekhupha ubude bobude obungasentla. Umzobo wesi-2 ziintsinga ezimbini ze-doped optical eziqhelekileyo ukuya kumazinga okufunxa anxulumene ne-800 ukuya kwi-1100 nm spectroscopy, kwaye kukho uphawu olubalulekileyo lokufunxa kufutshane ne-915 nm kunye ne-976 nm. Izinga lokufunxa kwamaza okukhanya angama-976nm kwifayibha yokulahla i-aluminosilicate iphantse yaphinda kathathu igagasi lokukhanya le-915 nm, kwaye isantya sokufunxa sangaphambili kwi-phosphosilicate siphantse sibe si-5 amaxesha okugqibela. Ukusilela okunjalo kwahlukile, okuthetha ukuba iilaser ezinjalo zamkela itekhnoloji yempompo ye-976nm LD ukufezekisa ukusebenza kakuhle koguqulo lokukhanya. Kwangaxeshanye, ukufunxa okuphezulu kuthetha ukunciphisa ngokufanelekileyo ubude befayibha, ngaloo ndlela kuthintelwa imiphumo eyingozi engaqhelekanga ukuya kumlinganiselo othile.
Umzobo we-3 Ijika le-Photon Dinoff (PD) Ilahleko ye-YB Ion yaManyathelo aMandla ahlukeneyo.
Okwangoku, ii-laser ze-doped fiber lasers ezisebenza ngamandla amakhulu kufuneka zijongane neengxaki zokufota. Le ngxaki ibangela ukuhla okukhulu kwamandla okuphuma kwelaser, ukuzinza kunye nobomi bokusebenza. Ubumnyama be-Photon I-phenomenon iphinda ichazwe kwinani elikhulu le-ion-doped fiber lasers. Ngokuqhelekileyo kuqwalaselwa ukuba le nto ibangelwa ngumbala-ziko eliveliswe kwi-matrix yeglasi. Uphononongo lwangaphambili lucebise indlela eninzi enokwenzeka yokusombulula le foton dacte, kubandakanywa ne-co-doped phosphorus kwifayibha, kusetyenziswa i-405 nm laser, i-photobleaching, nkqu nokusetyenziswa kobushushu obuphezulu, ukufakwa kwe-photon decimensing ye-photon kwenzeka. . Phakathi kwabo, nangona i-phosphorus inokunyanzeliswa ngokufanelekileyo, ilahleko yangasemva kunye nokuvuleka kwamanani kwandiswa.
Uphononongo lwangaphambili lweqela le-Koponen, kwi-photon emnyama lubonise ukuba i-photon intake yesantya ixhomekeke kakhulu kugxininiso lwe-excitation mites, oluyimeko yamandla ukuguqulwa kwe-ion (YB Inversion Rate). Baye bafumanisa ukuba i-photon intake rates yayilingana namaxesha e-7 kwi-ionic energy reversal rate. I-curve ye-photon intiminated ilahleko ngokuhamba kwexesha kwi-Fig 3 kwi-Fig 3 inikwe kwi-Fig 3. Idatha inembile kakhulu ukuba izinga lobumnyama be-photon landa ngokukhawuleza ngokunyuka kokuguqulwa kwamandla.
Umzobo 4, i-YB Ion Energy Reverse Rate Njengoko iPump Power Change Curve phantsi kwe-976 Nm kunye ne-920 NM Pump Condition (Cinga ukuba izinga lokubuyisela idatha ligudileyo ngokwaneleyo xa umahluko osemgangathweni ungaphantsi kwe-1%).
Izinga lokuguqulwa kwemeko yamandla kwifayibha ene-doped ichatshazelwa bubunzima befayibha, amandla empompo, impendulo yokukhanya, kunye nobude bobude bokukhanya kwempompo. Umgama wokukhanya wempompo efanelekileyo unokucinezelwa ubukhulu becala. Ukuguqulwa kwemeko ye-eneji kuchazwa ngokuqikelelwa njengomlinganiselo wokufunxa kwefotonic kunye necandelo elinqamlezayo lokukhutshwa kwinqanaba elithile lokukhanya kwempompo, kwaye ke imeko yamandla yefayibha ene-doped ifunyanwa phantsi kweemeko ezimbini zokukhanya kwepompo ye-976 nm kunye ne-920 nm. Izinga lokuguqulwa lihluka ngokutshintsha kwamandla epompo (umzobo 4). Nangona i-spectrum yokufunxa kwi-FIG 2 kwi-FiG 2 yokuqala ibonisa ukuba iimpawu zokufunxa kwe-976nm wavelength ukukhanya komelele kakhulu kunamanye amaza amaza, kodwa ngenxa yokuba i-976 nm ye-wavelength ukukhanya kukhulu kakhulu, ekugqibeleni ifunyenwe ngokukhanya kwempompo kunokukhanya. 920 nm. Amandla aphantsi kwimeko aphantsi. Nangona idatha ayizange inike ngokuthe ngqo ukuguqulwa kwamandla e-915 nm pump, kwakusenokwenzeka ukucinga ukuba umthombo wokukhanya wepompo ye-976nm unamandla anamandla okuchasana ne-optical sub-profiling kuneyangaphambili.
Nangona indlela yepompo ye-976nm inezinga eliphezulu lokufunxa kunye nokusebenza kakuhle kokuguqulwa kokukhanya, inokunciphisa ngokufanelekileyo ubude bokufumana ifayibha, kwaye umphumo onobungozi we-photon canache ungancitshiswa, kodwa uhambelana ne-915 nm imo yepompo yonyango kunye nokudibanisa. . Ubugcisa bunzima ngakumbi. Ngaphezu koko, i-spectrum yokufunxa yefiber ehlanganisiweyo kuluhlu lwe-976 nm luncinci kakhulu. Utshintsho lwe-wavelength olubangelwa ukuguquguquka kobushushu bomthombo wempompo kunokubangela ukuba amandla okukhutshwa kwe-laser angazinzi, kwaye le teknoloji yempompo inemfuno engqongqo kakhulu yenkqubo yokulawula ukushisa kwe-laser. Ngenxa yoku, bambalwa kuphela abavelisi be-laser abafana ne-IPG yaseJamani, i-United States Coherent-Rofin, kunye ne-US GW kunye nabanye abavelisi basebenzisa umthombo wempompo we-976 nm kwii-laser zamashishini amakhulu.
