Ukuzivelela kobugcisa kwelaser fibers zamandla aphezulu

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 lwefiber laser kunye nentsimi yophuhliso yaphuka iiwatts ezili-10,000 okokuqala ngqa, ulwakhiwo lwefiber laser ikakhulu kukusetyenziswa kokumpompa kwe-optical bidirectional, ukwenza iresonator, kunye nophando lokuphumelela kwethambeka lefiber. i-laser ifikelele kwi-58.3%.
Nangona kunjalo, nangona ukusetyenziswa kwe-fiber pump light kunye ne-laser coupling technology ukuphuhlisa i-fiber lasers kunokuphucula ngokufanelekileyo amandla emveliso ye-fiber lasers, kodwa kwangaxeshanye kukho ukuntsonkotha, okungahambi kakuhle kwi-lens optical ukwakha indlela yokubona, kanye i-laser idinga ukuhanjiswa kwinkqubo yokwakha indlela ye-optical, emva koko indlela ye-optical nayo ifuna ukulungiswa kwakhona, ethintela ukusetyenziswa okubanzi kwe-fiber optical structure fiber lasers.

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 iwavelength kwinkqubo ye-oscillation, ize ke ikhuphe iwavelength ekhethiweyo, ngelixa iMOPA isebenzisa iwavelength ekhethwe yigrayi njengokukhanya kwembewu, kwaye ukukhanya kwembewu kuyandiswa phantsi kwesenzo sokuqala. I-amplifier yezinga, ngoko ke amandla okuphuma kwe-fiber laser nawo aya kuphuculwa kwinqanaba elithile. Ixesha elide, i-fiber lasers ene-MPOA isakhiwo isetyenziswe njengesakhiwo esikhethiweyo se-laser fiber fibers. Nangona kunjalo, izifundo ezilandelayo ziye zafumanisa ukuba imveliso yamandla aphezulu kwesi sakhiwo kulula ukukhokelela ekungazinzini kokusabalalisa kwendawo ngaphakathi kwe-fiber laser, kunye nokukhanya kwe-laser okuphumayo kuya kuchaphazeleka kwinqanaba elithile, elikwanefuthe elithe ngqo. kwisiphumo semveliso yamandla 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 emkhosini, kwezonyango kunye nakwamanye amashishini, i-China ikhuthaze ukusetyenziswa okubanzi kwee-laser ze-fiber ngokusebenzisa phantse iminyaka engama-30 yophando lweteknoloji kunye nophuhliso, kodwa ukuba ufuna ukwenza i-laser fibers inokuvelisa amandla aphezulu, kusekho ezininzi iingxaki kubuchwephesha obukhoyo. 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 sephoton sibhekisa ikakhulu kwinto yokuba xa i-fiber laser iqhubeka ikhupha amakhulu eewatts okanye iikilowatts ezininzi zamandla, amandla emveliso aya kubonisa Ukuwohloka okukhawulezileyo, kwaye kukho inqanaba elithile lokusikelwa umda kwimveliso yamandla aphezulu aqhubekayo efiber laser.

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.
