Niki aUmuyoboro muto?
Umuyoboro muto wa laser, Ijambo "ubugari bwumurongo" bivuga ubugari bwumurongo walasermuri domaine yumurongo, mubisanzwe ubarwa ukurikije igice cya-mpinga yuzuye y'ubugari (FWHM). Umuyoboro mwinshi wibasiwe cyane nimirasire ya atome cyangwa ion zishimye, urusaku rwicyiciro, kunyeganyega kwa resonator, ubushyuhe bwubushyuhe nibindi bintu byo hanze. Gutoya agaciro k'ubugari bwumurongo, niko hejuru yubuziranenge bwikigereranyo, ni ukuvuga, monochromaticity ya laser. Lazeri ifite ibintu nkibi mubisanzwe ifite icyiciro gito cyane cyangwa urusaku rwinshi hamwe n urusaku ruke ugereranije. Mugihe kimwe, ntoya ntoya yubugari bwumurongo wa laser, niko gukomera bihuye, bigaragarira nkuburebure burebure cyane.
Kumenyekanisha no gukoresha umurongo muto wa laser
Bitewe ninyungu zisanzwe zifite imbaraga zumurimo wa lazeri, ntibishoboka ko umuntu amenya neza umusaruro wa lazeri yagutse yifashishije oscillator gakondo ubwayo. Kugirango tumenye imikorere ya laser linewidth laser, mubisanzwe birakenewe gukoresha muyungurura, gusya hamwe nibindi bikoresho kugirango ugabanye cyangwa uhitemo modulus ndende muburyo bwo kunguka ibintu, byongera inyungu zinyungu zinyuranye hagati yuburyo burebure, kuburyo habaho bike cyangwa ndetse nuburyo bumwe gusa bwo guhindagurika muburyo bwa laser resonator. Muri ubu buryo, akenshi birakenewe kugenzura ingaruka zurusaku rusohoka rwa laser, no kugabanya kwaguka kwimirongo iterwa no kunyeganyega nubushyuhe bwubushyuhe bwibidukikije; Muri icyo gihe, irashobora kandi guhuzwa hamwe nisesengura ryicyiciro cyangwa urusaku rwinshi rwurusaku rwinshi kugirango rwumve inkomoko y urusaku kandi rutezimbere igishushanyo mbonera cya laser, kugirango bigere kumusaruro uhamye wa lazeri ntoya.
Reka turebere hamwe mubikorwa byo kugabanya umurongo mugari wibyiciro bitandukanye bya laseri.
Amashanyarazi ya Semiconductor afite ibyiza byubunini buke, gukora neza, kuramba hamwe ninyungu zubukungu.
Fabry-Perot (FP) optique resonator ikoreshwa mubisanzweicyuma gikoreshamuri rusange iranyeganyega muburyo bwinshi-burebure, kandi ubugari bwumurongo bwagutse buragutse cyane, birakenewe rero kongera ibitekerezo bya optique kugirango tubone ibisubizo byumurongo mugari.
Ibitekerezo byatanzwe (DFB Laser) hamwe na Bragg yagaragajwe (DBR) nibintu bibiri bisanzwe byimbere byimbere byogutanga ibitekerezo bya semiconductor laseri. Bitewe n'akantu gato ko gusya hamwe no guhitamo kwiza kwinshi, biroroshye kugera kumurongo uhamye wumurongo umwe muto. Itandukaniro nyamukuru hagati yuburyo bubiri nu mwanya wo gusya: Imiterere ya DFB Laser isanzwe ikwirakwiza imiterere yigihe cya Bragg grating muri resonator yose, kandi resonator ya DBR mubisanzwe igizwe nuburyo bwo gusya bwerekana kandi akarere kunguka kinjijwe mubuso bwanyuma. Mubyongeyeho, laseri ya DFB ikoresha ibyashizwemo hamwe nibisobanuro bito byerekana ibintu bitagabanije. Lazeri ya DBR ikoresha ibishusho byo hejuru hamwe nibishobora guhinduka cyane. Izi nyubako zombi zifite intera nini yubusa kandi irashobora gukora uburebure bwumurongo udafite uburyo bwo gusimbuka muburyo bwa nanometero nkeya, aho laser ya DBR ifite intera yagutse kuruta iLaser. Mubyongeyeho, tekinoroji yo hanze yububiko bwa tekinoroji, ikoresha ibintu bya optique yo hanze kugirango isubize urumuri rwimuri rwa semiconductor laser chip hanyuma uhitemo inshuro, rushobora no kumenya imikorere yoroheje ya laser ya semiconductor laser.
(2) Ibikoresho bya fibre
Fibre ya fibre ifite pompe ihindura neza, ireme ryiza ryibiti hamwe no guhuza neza, nizo ngingo zishyushye mubushakashatsi bwa laser. Mubyerekeranye namakuru yamakuru, laseri ya fibre ihuza neza na sisitemu yo gutumanaho ya optique ya optique ku isoko. Umuyoboro umwe wa fibre laser hamwe nibyiza byubugari bwumurongo muto, urusaku ruto hamwe no guhuza neza byabaye kimwe mubyerekezo byingenzi byiterambere.
Imikorere imwe ya longitudinal imikorere niyo ntandaro ya fibre laser kugirango igere kumurongo ugutse-ubugari busohoka, mubisanzwe ukurikije imiterere ya resonator ya fibre fibre imwe ya fibre irashobora kugabanywa muburyo bwa DFB, ubwoko bwa DBR nubwoko bwimpeta. Muri byo, ihame ryakazi rya DFB Laser na DBR inshuro imwe ya fibre fibre irasa nkiya DFB na DBR semiconductor laseri.
Mu 1960, lazeri ya mbere ya rubyisi ku isi yari lazeri ikomeye, yaranzwe ningufu zitanga umusaruro mwinshi hamwe n’uburebure bwagutse. Imiterere yihariye ya laser-ikomeye ya laser ituma irushaho guhinduka mugushushanya kwagutse koroheje. Kugeza ubu, uburyo nyamukuru bwashyizwe mu bikorwa burimo uburyo bwa cavity ngufi, uburyo bumwe bwo kuzenguruka impeta, uburyo busanzwe bwa interacavity, uburyo bwa torsion pendulum uburyo bwa cavity uburyo, ingano ya Bragg yo gufata hamwe nuburyo bwo gutera imbuto.
