BWT yatanze igitekerezo cyo gutondekanya ahantu hatandukanye (DSBC) no kugenzura niba DSBC ari ukuri hifashishijwe igeragezwa rya pompe yo ku rwego rwa kilowatt.Kugeza ubu, imbaraga z'umuyoboro umwe zongerewe kugera kuri 15W-30W @ BPP≈5-12mm * mrad kandi imikorere ya electro-optique ni> 60%, ituma isoko ya pompe ifite ingufu nyinshi hamwe n’ibisohoka kugirango ikomeze hejuru umucyo usohoka mugihe ugabanya ingano, Birashoboka kugabanya uburemere no kunoza imikorere ya electro-optique.
Ukoresheje chip iriho, BWT yamenye isoko ya pompe ifite diameter yibanze ya 135μm NA0.22 fibre ihujwe na fibre 420W yumurambararo wafunzwe kuri 976nm, ubuziranenge ≈ 500g;na diameter yibanze ya 220μm NA0.22 fibre ihujwe hamwe 1000W imwe yumuraba umwe 976nm (cyangwa 915nm), ubuziranenge ≈ 400g isoko ya pompe.
Mu bihe biri imbere, hamwe no kunoza imishwarara ya semiconductor hamwe na electro-optique, ingufu za pompe zoroheje kandi zifite ingufu nyinshi zizagira uruhare rudasubirwaho mugukora ibicuruzwa bito bito bito bito bito bito bito, kandi bizateza imbere iterambere by'inganda zikoreshwa.
Intangiriro
Lazeri ya fibre yakuze vuba bitewe nubwiza buhebuje bwibiti hamwe nubushobozi bwo kwagura imbaraga (fibre combiners).Mu myaka yashize, lazeri imwe-imwe ya fibre fibre igarukira kuri TMI (transvers mode instabilite) hamwe ningaruka za SRS, kandi imbaraga za semiconductor zita pompe fibre laser oscillator zigarukira kuri 5kW
[1].Amplifier ya laser nayo ihagarikwa kuri 10kW
[2].Nubwo imbaraga zisohoka zishobora kwiyongera mugukwirakwiza neza diameter yibanze, ubwiza bwibisohoka nabyo bigabanuka -1.Nubwo bimeze bityo ariko, icyifuzo cyo kunoza umucyo wa pompe ya semiconductor iracyihutirwa.
Ibisabwa kugirango ubuziranenge bwibiti bishoboke gutunganya inganda ntabwo byanze bikunze.Kugirango wongere imbaraga za fibre imwe, uburyo buke bwo gutondekanya buremewe.Kugeza ubu, uburyo-bumwe-bumwe bwa fibre hamwe na beam-bihujwe nuburyo bwinshi bwa laser yumucyo ushingiye kuri 976nm kuvoma hejuru ya 5kW Hamwe nibisabwa (cyane cyane gukata no gusudira ibikoresho byicyuma), kubyara amasoko yingufu zikomoka kumashanyarazi. ni icyiciro-kinini.
Ntoya, yoroshye kandi ihamye
Isano iri hagati ya chip semiconductor chip BPP nubucyo bwisoko rya pompe
Imyaka itatu irashize, umucyo wa 9xxnm chips ahanini wari kurwego rwa 3W / mm * mrad @ 12W-100μm ubugari bwumugozi & 2W / mm * mrad @ 18W-200μm ubugari.Ukurikije izo chip, BWT igera kuri 600W na 1000W 200μm NA0.22 fibre ihujwe n'ibisohoka-1.
Kugeza ubu, ubwiza bwa chipi 9xxnm bwageze kuri 3.75W/mm*mrad@15W-100μm ubugari bwa strip & 3W / mm * mrad @ 30W-230μm ubugari bwumugozi, kandi imikorere ya electro-optique ikomeza kubikwa hafi 60%.
Ukurikije inyigisho yuburyo butondekanye ahantu hatandukanye [6], ibarwa ukurikije impuzandengo yo guhuza fibre ya 78% (imyuka ya laser iva muri chip ikagera kuri fibre fibre fibre: urumuri rwumurambararo umwe rukumbi uhuza urumuri hamwe na polarisiyasi ihuza nta VBG), kandi hafatwa ko chip ikora ku mbaraga zisumba izindi (Chip BPP iratandukanye ku miyoboro itandukanye), twakoze ikarita yamakuru ku buryo bukurikira:
* Chip Brightness VS Itandukanye Core Diameter Fibre Ihuza Imbaraga zisohoka
Irashobora kuboneka uhereye kumashusho yavuzwe haruguru ko mugihe fibre runaka (diameter yibanze na NA ikosowe) igera kumasoko yihariye yo guhuza imbaraga, kuri chip hamwe numucyo utandukanye, umubare wa chip uratandukanye, nubunini nuburemere byamasoko ya pompe nazo ziratandukanye.Kubisabwa byo kuvoma fibre ya fibre, niba isoko ya pompe ikozwe muri chip yavuzwe haruguru hamwe nubucyo butandukanye bwatoranijwe, uburemere nubunini bwa fibre laser yingufu zimwe biratandukanye rwose, kandi iboneza rya sisitemu yo gukonjesha amazi nayo iratandukanye. bitandukanye cyane.
Ubushobozi buhanitse, ubunini buto nuburemere bworoshye nibyo byanze bikunze bigenda bitera imbere mu iterambere ry’umucyo uzaza (yaba diode ya diode, ibyuma bikomeye bya lazeri cyangwa fibre ya fibre), kandi umucyo, imikorere n'imbaraga za chipi ya semiconductor bigira uruhare rukomeye muri yo .
Umucyo woroshye, urumuri rwinshi, isoko ya pompe ikomeye
Kugirango duhuze na fibre fibre, twahisemo fibre isanzwe: 135μm NA0.22 na 220μm NA0.22.Igishushanyo mbonera cya pompe zombi zifata umwanya munini hamwe na polarisiyasi ihuza.
Muri byo, 420WLD ifata 3.75W/mm*mrad@15W chip na fibre 135μm NA0.22, kandi ifite gufunga umurongo wa VBG, byujuje ibisabwa byo gufunga amashanyarazi 30-100%, kandi amashanyarazi ya optique ni 41% .Umubiri wa LD ukozwe mu bikoresho bya aluminiyumu hamwe na sandwich [5].Chip yo hejuru no hepfo isangira umuyoboro ukonjesha amazi, utezimbere imikoreshereze yumwanya.Itara ryumucyo, spekiteri nimbaraga zisohoka (imbaraga muri fibre) zerekanwa mumashusho:
* 420W @ 135μm NA0.22 LD
Twahisemo LDs 6 zo hejuru no hasi yubushyuhe no gupima ibizamini.Amakuru yikizamini ni aya akurikira:
* Ikizamini cyo hejuru yubushyuhe bwo hasi
Ikizamini cyo kunyeganyega
1000WLD ifata chip ya 3W / mm * mrad @ 30W hamwe na fibre 220μm NA0.22, igera kuri 915nm na 976nm fibre ihujwe na 1000W, kandi amashanyarazi ya optique ni> 44%.Umubiri wa LD nawo wakozwe mubikoresho bya aluminium.Kugirango dukurikirane imbaraga zisumba izindi-mbaga, LD shell yoroshye muburyo bwo kwemeza imbaraga zubaka.Ubwiza bwa LD, ibiboneka hamwe nimbaraga zisohoka (imbaraga muri fibre) nibi bikurikira:
* 1000W @ 220μm NA0.22 LD
Kugirango tunonosore kwizerwa ryamasoko ya pompe, fibre end fibre ifata quartz end cap fusion hamwe nikoranabuhanga ryungurura urumuri, ibyo bigatuma ubushyuhe bwa fibre hanze yisoko ya pompe hafi yubushyuhe bwicyumba.Batandatu 976nmLDs batoranijwe kugirango habeho ubushyuhe bwo hejuru nubushyuhe bwo hasi no kwipimisha.Ibisubizo by'ibizamini ni ibi bikurikira:
* Ikizamini cyo hejuru yubushyuhe bwo hasi
* Ikizamini cyo hejuru yubushyuhe bwo hasi
Ikizamini cyo kunyeganyega
Umwanzuro
Kugera kumurabyo mwinshi biva muburyo bwo gukoresha amashanyarazi ya optique, ni ukuvuga imbaraga zisohoka cyane hamwe nubushobozi buhanitse bwa electro-optique ntibishobora kuboneka icyarimwe, bigenwa numucyo wa chip hamwe ninshuro zisanzwe zo guhuza. fibre.Muri byinshi-imwe-ya-tube ya beam igizwe na tekinoroji, umucyo nubushobozi buri gihe intego zidashobora kugerwaho icyarimwe.Impuzandengo ya electro-optique ikora neza nimbaraga bigomba kugenwa ukurikije porogaramu yihariye.
