Ufezekiso lweifayibha laserisakhiwo

I-1, isakhiwo sempompo yokukhanya kwendawo

Iilaser zefiber zakwangoko zazisetyenziswa kakhulu ukuphuma kwempompo ye-optical,laserimveliso, amandla ayo aphumayo aphantsi, ukuze kuphuculwe ngokukhawuleza amandla emveliso yefiber lasers ngexesha elifutshane kukho ubunzima obukhulu. Ngo-1999, amandla emveliso yophando lwe-fiber laser kunye nentsimi yophuhliso yaphuka i-10,000 watts okokuqala, isakhiwo se-fiber laser ikakhulu kukusetyenziswa kokumpompa kwe-optical bidirectional, ukwenza i-resonator, kunye nophando lwe-slope ye-slope ye-fiber laser ifikelele kwi-58.3%.
Nangona kunjalo, nangona ukusetyenziswa kwe-fiber pump light kunye ne-laser coupling technology ukuphuhlisa i-laser fibers kunokuphucula ngokufanelekileyo amandla emveliso ye-fiber lasers, kodwa kwangaxeshanye kukho ukuntsonkotha, okungahambi kakuhle kwilensi yokubona ukwakha indlela yokubona, kanye nje ukuba i-laser ifune ukushukunyiswa kwinkqubo yokwakha indlela yokubona, emva koko indlela yamehlo nayo ifuna ukulungiswa kwakhona kwimpompo ye-fiber optical.

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

Ngophuhliso lweelaser zefiber, ii-cladding power strippers ziye zatshintsha ngokuthe ngcembe amacandelo e-lens, enza lula amanyathelo ophuhliso lwe-fiber lasers kunye nokuphucula ngokungathanga ngqo ugcino lwe-fiber lasers. Lo mkhwa wophuhliso ubonakalisa ukusebenza kancinci kancinci kwefiber lasers. Ulwakhiwo oluthe ngqo lwe-oscillator kunye nolwakhiwo lwe-MOPA zezona zakhiwo ziqhelekileyo ze-fiber lasers kwimarike. Ulwakhiwo oluthe ngqo lwe-oscillator kukuba igrayiti ikhetha ubude bamaza kwinkqubo ye-oscillation, kwaye emva koko ikhuphe i-wavelength ekhethiweyo, ngelixa i-MOPA isebenzisa i-wavelength ekhethwe yi-grating njengokukhanya kwembewu, kwaye ukukhanya kwembewu kukhuliswe phantsi kwesenzo se-amplifier yenqanaba lokuqala, ngoko ke amandla okuphuma kwe-laser fiber nawo aya kuphuculwa ukuya kwinqanaba elithile. Ixesha elide, i-fiber lasers ene-MPOA isakhiwo isetyenziswe njengesakhiwo esikhethiweyo se-laser fiber fibers. Nangona kunjalo, uphando olulandelayo lufumene ukuba ukuveliswa kwamandla aphezulu kwesi sakhiwo kulula ukukhokelela ekungazinzini kokusabalalisa kwendawo ngaphakathi kwe-fiber laser, kunye nokukhanya kwe-laser ye-output kuya kuchaphazeleka kwinqanaba elithile, elikwanefuthe elithe ngqo kwisiphumo sokuphuma kwamandla aphezulu.

Ngophuhliso lweteknoloji yokupompa

Umgama wokumpompa we-laser ye-ytterbium-doped fibre yokuqala idla ngokuba yi-915nm okanye i-975nm, kodwa la maza mabini okumpompa ziincopho zokufunxa ii-ion ze-ytterbium, ke kubizwa ngokuba kukumpompa ngokuthe ngqo, ukumpompa ngokuthe ngqo akukhange kusetyenziswe ngokubanzi ngenxa yokulahleka komyinge. Itekhnoloji yokupompa i-in-band yongezwa kweteknoloji yokupompa ngokuthe ngqo, apho ubude be-wavelength phakathi kwe-wavelength yokupompa kunye ne-wavelength yokudlulisa iyafana, kwaye izinga lokulahleka kwe-quantum lokupompa kwi-band lincinci kunelo lokupompa ngokuthe ngqo.

Ilaser yefiber ephezulu yamandlaumqobo wophuhliso lwetekhnoloji

Nangona i-fiber lasers inexabiso eliphezulu lesicelo kumashishini, ezonyango kunye nakwamanye amashishini, i-China ikhuthaze ukusetyenziswa okubanzi kwee-laser ze-fiber malunga neminyaka engama-30 yophando lweteknoloji kunye nophuhliso, kodwa ukuba ufuna ukwenza i-laser fibers inokuvelisa amandla aphezulu, kusekho ezininzi iibhotile kwi-teknoloji ekhoyo. Umzekelo, ingaba amandla okukhutshwa kwe-fiber laser anokufikelela kwi-fiber enye-mode eyodwa ye-36.6KW; Impembelelo yamandla okumpompa kwifiber laser output power; Impembelelo ye-lens ye-thermal kumandla ophumayo we-fiber laser.

Ukongeza, uphando lwetekhnoloji ephezulu yokukhupha amandla e-fiber laser kufuneka kwakhona ithathele ingqalelo uzinzo lwemowudi enqamlezayo kunye nesiphumo sobumnyama befoton. Ngophando, kucacile ukuba impembelelo yendlela yokungazinzi kwemowudi enqamlezileyo kukufudumeza kwefayibha, kwaye isiphumo sobumnyama sefoton sibhekisa ikakhulu kwinto yokuba xa i-fiber laser iqhubeka ikhupha amakhulu eewatts okanye iikilowathi ezininzi zamandla, amandla emveliso aya kubonisa ukuhla okukhawulezayo, kwaye kukho inqanaba elithile lokusikelwa umda kwimveliso yamandla aphezulu eqhubekayo yelaser yefiber.

Nangona izizathu ezithile zempembelelo ye-photon emnyama azichazwanga ngokucacileyo okwangoku, abaninzi abantu bakholelwa ukuba iziko le-oksijini yesiphene kunye nokugqithiswa kwentlawulo kunokukhokelela ekubeni kwenzeke i-photon mnyama. Kule miba mibini, iindlela ezilandelayo zicetywayo ukuthintela umphumo we-photon mnyama. Njenge-aluminiyam, i-phosphorus, njl., ukuze uthintele ukugqithiswa kwentlawulo, kwaye emva koko i-fiber esebenzayo ephuculweyo iyavavanywa kwaye isetyenziswe, umgangatho othile kukugcina imveliso yamandla e-3KW iiyure ezininzi kunye nokugcina imveliso yamandla e-1KW ezinzileyo kwiiyure ezili-100.
