Fibre-ifatanije na Laser Diode Ibisobanuro, Ihame ryakazi, hamwe nuburebure busanzwe
Fibre ihujwe na laser diode nigikoresho cya semiconductor gitanga urumuri rwuzuye, hanyuma rukibandwaho kandi rugahuzwa neza kugirango ruhuze umugozi wa fibre optique. Ihame shingiro ririmo gukoresha amashanyarazi kugirango akangure diode, gukora fotone binyuze mubyuka bihumanya. Izi fotone zongerewe muri diode, zitanga urumuri rwa laser. Binyuze mu kwibanda no guhuza neza, urumuri rwa laser rwerekejwe mumurongo wa fibre optique, aho yanduzwa nigihombo gito nukuzirikana kwimbere.
Urwego rwuburebure
Uburebure busanzwe bwa fibre ihujwe na laser diode module irashobora gutandukana cyane bitewe nicyo igenewe. Mubisanzwe, ibyo bikoresho birashobora gukwirakwiza intera ndende yuburebure, harimo:
Umucyo ugaragara:Uhereye kuri 400 nm (violet) kugeza kuri 700 nm (umutuku). Ibi bikunze gukoreshwa mubisabwa bisaba urumuri rugaragara rwo kumurika, kwerekana, cyangwa kumva.
Hafi-Infrared (NIR):Guhinduka kuva kuri 700 nm kugeza kuri 2500 nm. Uburebure bwa NIR bukoreshwa cyane mubitumanaho, mubikorwa byubuvuzi, hamwe ninganda zitandukanye.
Hagati (MIR): Kwaguka kurenga 2500 nm, nubwo bitamenyerewe mubisanzwe fibre ihujwe na laser diode modules kubera porogaramu yihariye nibikoresho bya fibre bisabwa.
Lumispot Tech itanga fibre ihujwe na laser diode module hamwe nuburebure busanzwe bwa 525nm, 790nm, 792nm, 808nm, 878.6nm, 888nm, 915m, na 976nm kugirango duhure nabakiriya batandukanye.'Porogaramu.
Ibisanzwe A.gusabas ya fibre ihujwe na laseri ku burebure butandukanye
Aka gatabo karerekana uruhare rukomeye rwa fibre ihujwe na laser diode (LDs) mugutezimbere tekinoroji ya pompe nuburyo bwo kuvoma optique muri sisitemu zitandukanye. Mugushimangira uburebure bwihariye bwumurongo hamwe nibisabwa, turagaragaza uburyo iyi diode ya laser ihindura imikorere nibikorwa bya fibre hamwe na reta ikomeye.
Gukoresha Fibre-Ifatanije na Laser nka Pompe Inkomoko ya Fibre
915nm na 976nm Fibre Ifatanije LD nkisoko ya pompe ya 1064nm ~ 1080nm fibre fibre.
Kubikoresho bya fibre ikora muri 1064nm kugeza 1080nm, ibicuruzwa bifashisha uburebure bwa 915nm na 976nm birashobora kuba isoko ya pompe nziza. Ibi bikoreshwa cyane cyane mubikorwa nko gukata lazeri no gusudira, kwambara, gutunganya lazeri, gushyira akamenyetso, hamwe nintwaro zikomeye za laser. Inzira, izwi nka pompe itaziguye, ikubiyemo fibre ikurura urumuri rwa pompe kandi ikohereza mu buryo butaziguye nka laser isohoka mu burebure bwa 1064nm, 1070nm, na 1080nm. Ubu buryo bwo kuvoma bukoreshwa cyane mubushakashatsi bwubushakashatsi hamwe nubusanzwe inganda zikoreshwa mu nganda.
Fibre ihujwe na laser diode hamwe na 940nm nkisoko ya pompe ya 1550nm fibre laser
Mu rwego rwa 1550nm fibre fibre, fibre ihujwe na fibre ifite uburebure bwa 940nm ikunze gukoreshwa nkisoko ya pompe. Iyi porogaramu ifite agaciro cyane mubijyanye na laser LiDAR.
Porogaramu idasanzwe ya Fibre ihujwe na laser diode hamwe na 790nm
Fibre ihujwe na fibre kuri 790nm ntabwo ikora gusa nkisoko ya pompe ya fibre fibre ahubwo iranakoreshwa mumashanyarazi akomeye. Zikoreshwa cyane nkisoko ya pompe ya lazeri ikorera hafi yumurambararo wa 1920nm, hamwe nibisabwa muburyo bwo guhangana nifoto.
Porogaramuya Fibre-Ihujwe na Laser nka Pompe Inkomoko ya Solid-leta Laser
Kuri lazeri ikomeye-isohora hagati ya 355nm na 532nm, fibre ihujwe na fibre ifite uburebure bwa 808nm, 880nm, 878.6nm, na 888nm nibyo byatoranijwe. Ibi bikoreshwa cyane mubushakashatsi bwa siyanse no guteza imbere lazeri-ikomeye muri violet, ubururu, nicyatsi kibisi.
Porogaramu itaziguye ya Semiconductor Lasers
Porogaramu ya semiconductor itaziguye ikubiyemo ibisohoka bitaziguye, guhuza lens, guhuza imiyoboro yumuzunguruko, hamwe no guhuza sisitemu. Lazeri ihujwe na fibre ifite uburebure bwa 450nm, 525nm, 650nm, 790nm, 808nm, na 915nm ikoreshwa mubikorwa bitandukanye birimo kumurika, kugenzura gari ya moshi, kureba imashini, hamwe na sisitemu z'umutekano.
Ibisabwa kuri pompe yinkomoko ya fibre hamwe na reta ikomeye.
Kugirango usobanukirwe birambuye ibisobanuro bya pompe ibisabwa kuri fibre ya fibre na lazeri-ikomeye, ni ngombwa gucukumbura umwihariko wukuntu izo lazeri zikora nuruhare rwamasoko ya pompe mumikorere yabyo. Hano, tuzaguka kubisobanuro rusange byambere kugirango dusuzume uburyo bukomeye bwo kuvoma, ubwoko bwa pompe zikoreshwa, ningaruka zabyo kumikorere ya laser. Guhitamo no kugena amasoko ya pompe bigira ingaruka kuburyo butaziguye imikorere ya laser, imbaraga zisohoka, hamwe nubwiza bwibiti. Guhuza neza, guhuza umurongo, hamwe nubuyobozi bwumuriro nibyingenzi mugutezimbere imikorere no kwagura ubuzima bwa laser. Iterambere mu buhanga bwa laser diode rikomeje kunoza imikorere no kwizerwa byombi bya fibre hamwe na reta-ikomeye-ya lazeri, bigatuma irushaho guhinduka kandi ihendutse kubikorwa byinshi.
- Fibre Laser Pomp Inkomoko Ibisabwa
Laser Diodenka Pompe Inkomoko:Fibre ya fibre yiganjemo gukoresha diode ya lazeri nkisoko ya pompe bitewe nubushobozi bwayo, ingano yoroheje, hamwe nubushobozi bwo gutanga uburebure bwihariye bwurumuri rujyanye no kwinjiza ibintu bya fibre. Guhitamo laser diode yumurambararo ni ngombwa; kurugero, dopant isanzwe muri fibre ya fibre ni Ytterbium (Yb), ifite impinga nziza yo kwinjiza hafi 976 nm. Kubwibyo, diode ya laser isohoka cyangwa hafi yu burebure bwumurongo bikundwa kuvoma Yb-dope fibre lazeri.
Igishushanyo mbonera cya Fibre ebyiri:Kugirango wongere imikorere yumucyo ukomoka kuri pompe ya laser diode, laseri ya fibre akenshi ikoresha fibre yambaye kabiri. Intangiriro y'imbere ikoporowe hamwe na lazeri ikora (urugero, Yb), mugihe hanze, binini byambaye byayobora urumuri rwa pompe. Intangiriro ikurura urumuri rwa pompe kandi ikabyara ibikorwa bya laser, mugihe kwambikwa kwemerera umubare munini wumucyo wa pompe kugirango uhuze ningingo, byongera imikorere.
Guhuza Umuhengeri no guhuza neza: Kuvoma neza ntibisaba gusa guhitamo diode ya lazeri hamwe nuburebure bukwiye ariko kandi binanonosora uburyo bwo guhuza hagati ya diode na fibre. Ibi bikubiyemo guhuza neza no gukoresha ibikoresho bya optique nka lens hamwe na kuperi kugirango urumuri ntarengwa rwa pompe rwinjizwe muri fibre fibre cyangwa yambaye.
-Ibikoresho bikomeyeAmashanyarazi asabwa
Kuvoma neza:Usibye diode ya lazeri, lazeri-ikomeye (harimo na laseri nyinshi nka Nd: YAG) irashobora kuvomerwa neza n'amatara ya flash cyangwa amatara ya arc. Aya matara asohora urumuri rugari rw'umucyo, igice cyacyo kikaba gihuye n'imigozi yo kwinjiza ya lazeri. Mugihe bidakorwa neza kuruta kuvoma laser diode, ubu buryo burashobora gutanga ingufu zingana cyane, bigatuma bukoreshwa mubisabwa bisaba imbaraga zo hejuru.
Ibikoresho bya pompe Iboneza:Iboneza rya pompe yinkomoko muburyo bukomeye bwa lazeri irashobora guhindura cyane imikorere yabo. Kurangiza-kuvoma no gupompa kuruhande nibisanzwe. Kurangiza-pompe, aho itara rya pompe ryerekejwe kumurongo wa optique ya laser yo hagati, itanga guhuzagurika neza hagati yumucyo wa pompe nuburyo bwa laser, biganisha kumikorere myiza. Kuvoma kuruhande, nubwo bishoboka ko bidakorwa neza, biroroshye kandi birashobora gutanga ingufu rusange muri rusange kumpande nini ya diameter.
Gucunga Ubushyuhe:Byombi fibre hamwe na reta ikomeye ikenera gucunga neza ubushyuhe kugirango ikemure ubushyuhe buturuka kumasoko ya pompe. Muri laseri ya fibre, ubuso bwagutse bwa fibre ifasha mukwirakwiza ubushyuhe. Muri lazeri-ikomeye, sisitemu yo gukonjesha (nko gukonjesha amazi) irakenewe kugirango ikomeze imikorere ihamye kandi irinde ubushyuhe bwumuriro cyangwa kwangiza uburyo bwa laser.
