Uphuhliso lobuchwephesha lwe-laser yefayibha enamandla aphezulu

Ukuphucula ukusebenza kwei-laser yefayibhaisakhiwo

1, isakhiwo sepompo yokukhanya kwendawo

Iilaser zefayibha zakuqala zazisebenzisa kakhulu imveliso yepompo ye-optical,ilezaimveliso, amandla ayo okukhupha aphantsi, ukuze kuphuculwe ngokukhawuleza amandla okukhupha e-fiber lasers ngexesha elifutshane kukho ubunzima obukhulu. Ngo-1999, amandla okukhupha entsimini yophando nophuhliso lwe-fiber laser aphule i-10,000 watts okokuqala, ulwakhiwo lwe-fiber laser lusetyenziswa kakhulu yi-optical bidirectional pumping, eyenza i-resonator, kunye nophando lokusebenza kakuhle kwe-slope ye-fiber laser lufikelele kwi-58.3%.
Nangona kunjalo, nangona ukusetyenziswa kobuchwepheshe bokukhanya kwepompo yefayibha kunye netekhnoloji yokudibanisa ilaser ukuphuhlisa iilaser zefayibha kunokuphucula ngempumelelo amandla okukhupha iilaser zefayibha, kodwa kwangaxeshanye kukho ubunzima, obungalungelanga ilensi yokukhanya ukwakha indlela yokukhanya, xa ilaser kufuneka ishukunyiswe kwinkqubo yokwakha indlela yokukhanya, ke indlela yokukhanya nayo kufuneka ihlengahlengiswe, nto leyo ethintela ukusetyenziswa ngokubanzi kweelaser zefayibha zesakhiwo sepompo yokukhanya.

2, isakhiwo se-oscillator ngqo kunye nesakhiwo se-MOPA

Ngophuhliso lwee-laser zefayibha, ii-cladding power strippers ziye zatshintsha kancinci kancinci izinto zelensi, zenza lula amanyathelo ophuhliso lwee-laser zefayibha kwaye ziphucula ngokungathanga ngqo ukusebenza kakuhle kokugcinwa kwee-laser zefayibha. Olu phuhliso lubonisa ukusebenza kancinci kancinci kwee-laser zefayibha. Ulwakhiwo lwe-oscillator ethe ngqo kunye nolwakhiwo lwe-MOPA zezona zakhiwo zimbini ziqhelekileyo zee-laser zefayibha kwimarike. Ulwakhiwo lwe-oscillator ethe ngqo kukuba i-grating ikhetha ubude be-wavelength kwinkqubo ye-oscillation, ize ikhuphe ubude be-wavelength obukhethiweyo, ngelixa i-MOPA isebenzisa ubude be-wavelength obukhethwe yi-grating njengokukhanya kwembewu, kwaye ukukhanya kwembewu kuyandiswa phantsi kwesenzo se-amplifier yenqanaba lokuqala, ngoko ke amandla okukhupha e-laser yefayibha nawo aya kuphuculwa ukuya kwinqanaba elithile. Kangangexesha elide, ii-laser zefayibha ezinesakhiwo se-MPOA ziye zasetyenziswa njengesakhiwo esithandwayo kwii-laser zefayibha ezinamandla aphezulu. Nangona kunjalo, izifundo ezilandelayo zifumanise ukuba isiphumo samandla aphezulu kwesi sakhiwo kulula ukukhokelela ekungazinzini kokusasazwa kwendawo ngaphakathi kwe-fiber laser, kwaye ukukhanya kwe-output laser kuya kuchaphazeleka kwinqanaba elithile, nto leyo enefuthe ngqo kwisiphumo sesiphumo samandla aphezulu.

Ngophuhliso lwetekhnoloji yokupompa

Ubude bomphezulu bokupompa be-laser yefayibha ye-ytterbium yokuqala budla ngokuba yi-915nm okanye i-975nm, kodwa ezi yure zimbini zomphezulu womphezulu ziincopho zokufunxa ii-ion ze-ytterbium, ngoko ke zibizwa ngokuba kukupompa ngokuthe ngqo, ukupompa ngokuthe ngqo akusetyenziswanga kakhulu ngenxa yokulahleka kwe-quantum. Itekhnoloji yokupompa ngaphakathi kwebhendi lulwandiso lwetekhnoloji yokupompa ngokuthe ngqo, apho ubude bomphezulu phakathi kobude bomphezulu wo ...

I-laser yefayibha enamandla aphezuluumqobo wophuhliso lobuchwepheshe

Nangona ii-laser zefayibha zixabisa kakhulu kwimizi-mveliso yasemkhosini, kwezonyango nakwamanye amashishini, iTshayina ikhuthaze ukusetyenziswa ngokubanzi kwee-laser zefayibha kwiminyaka ephantse ibe ngama-30 yophando nophuhliso lobuchwepheshe, kodwa ukuba ufuna ukwenza ii-laser zefayibha zinokukhupha amandla aphezulu, kusekho imiqobo emininzi kubuchwepheshe obukhoyo. Umzekelo, ukuba amandla okukhupha e-laser yefayibha anokufikelela kwi-single-fiber single-mode 36.6KW; Impembelelo yamandla okupompa kumandla okukhupha e-fiber laser; Impembelelo yempembelelo yelensi yobushushu kumandla okukhupha e-fiber laser.

Ukongeza, uphando lwetekhnoloji yokukhupha amandla aphezulu ye-fiber laser kufuneka luqwalasele ukuzinza kwe-transverse mode kunye ne-photon darkening effect. Ngophando, kuyacaca ukuba impembelelo ye-transverse mode instability kukufudumala kwe-fiber, kwaye i-photon darkening effect ibhekisa ikakhulu ekubeni xa i-fiber laser ikhupha amakhulu ee-watts okanye ii-kilowatts ezininzi zamandla ngokuqhubekayo, amandla okukhupha aya kubonisa umkhwa wokuhla ngokukhawuleza, kwaye kukho umda othile kwi-continuous high power output ye-fiber laser.

Nangona izizathu ezithile zesiphumo sobumnyama be-photon zingakhange zichazwe ngokucacileyo okwangoku, uninzi lwabantu lukholelwa ukuba iziko le-oxygen defect kunye nokufunxwa kwetshaja kunokukhokelela ekuveleni kwesiphumo sobumnyama be-photon. Kule miba mibini, kucetyiswa iindlela ezilandelayo zokuthintela isiphumo sobumnyama be-photon. Ezifana ne-aluminium, i-phosphorus, njl.njl., ukuze kuthintelwe ukufunxwa kwetshaja, kwaye emva koko i-fiber esebenzayo ephuculiweyo iyavavanywa kwaye isetyenziswe, umgangatho othile kukugcina amandla e-3KW iiyure ezininzi kunye nokugcina amandla e-1KW ezinzileyo ephuma iiyure ezili-100.
