Tanthauzo la Diode ya Laser Yolumikizidwa ndi Ulusi, Mfundo Yogwirira Ntchito, ndi Kutalika Kwa Mafunde Kwachizolowezi
Diode ya laser yolumikizidwa ndi ulusi ndi chipangizo cha semiconductor chomwe chimapanga kuwala kogwirizana, komwe kumayikidwa bwino ndikulumikizidwa bwino kuti kuphatikizidwe mu chingwe cha fiber optic. Mfundo yaikulu imaphatikizapo kugwiritsa ntchito mphamvu yamagetsi kuti ilimbikitse diode, ndikupanga ma photon kudzera mu mpweya wolimbikitsidwa. Ma photon awa amakulitsidwa mkati mwa diode, ndikupanga kuwala kwa laser. Mwa kuyang'ana mosamala ndi kulinganiza, kuwala kwa laser kumeneku kumalunjika pakati pa chingwe cha fiber optic, komwe kumatumizidwa popanda kutayika kwakukulu chifukwa cha kuwunikira konse kwamkati.
Mtundu wa Mafunde
Kutalika kwa nthawi ya mafunde a laser diode module yolumikizidwa ndi ulusi kumatha kusiyana kwambiri kutengera momwe ikugwiritsidwira ntchito. Kawirikawiri, zipangizozi zimatha kugwiritsa ntchito mafunde osiyanasiyana, kuphatikizapo:
Sipekitiramu Yowala Yooneka:Kuyambira pafupifupi 400 nm (violet) mpaka 700 nm (wofiira). Izi nthawi zambiri zimagwiritsidwa ntchito pa ntchito zomwe zimafuna kuwala kooneka kuti ziunikire, ziwonetse, kapena zizindikire.
Pafupi ndi Infrared (NIR):Mafunde a NIR amagwiritsidwa ntchito kwambiri pakulankhulana, ntchito zachipatala, ndi ntchito zosiyanasiyana zamafakitale.
Mid-Infrared (MIR): Imafalikira kupitirira 2500 nm, ngakhale kuti si yofala kwambiri m'ma modules a laser diode olumikizidwa ndi ulusi chifukwa cha ntchito zapadera komanso zipangizo za ulusi zomwe zimafunika.
Lumispot Tech imapereka gawo la diode la laser lolumikizidwa ndi ulusi wokhala ndi ma wavelengths wamba a 525nm, 790nm, 792nm, 808nm, 878.6nm, 888nm, 915m, ndi 976nm kuti akwaniritse makasitomala osiyanasiyana.'zosowa za pulogalamu.
Wamba Akubwerezabwerezas ma laser olumikizidwa ndi ulusi pa ma wavelength osiyanasiyana
Bukuli likufotokoza za ntchito yofunika kwambiri ya ma diode a laser olumikizidwa ndi ulusi (LDs) pakupititsa patsogolo ukadaulo wa magwero a mapampu ndi njira zopopera kuwala m'machitidwe osiyanasiyana a laser. Mwa kuyang'ana kwambiri ma wavelengths enaake ndi momwe amagwiritsidwira ntchito, tikuwonetsa momwe ma diode a laser awa amasinthira magwiridwe antchito ndi magwiridwe antchito a ma laser a fiber ndi solid-state.
Kugwiritsa Ntchito Ma Laser Ophatikizana ndi Ulusi Monga Magwero a Mapampu a Ma Laser a Ulusi
915nm ndi 976nm Fiber Coupled LD monga gwero la pampu ya 1064nm ~ 1080nm fiber laser.
Pa ma laser a ulusi omwe amagwira ntchito mu 1064nm mpaka 1080nm, zinthu zomwe zimagwiritsa ntchito ma wavelength a 915nm ndi 976nm zitha kukhala magwero othandiza a pampu. Izi zimagwiritsidwa ntchito makamaka mu ntchito monga kudula ndi kuwotcherera ndi laser, cladding, laser processing, marking, ndi zida za laser zamphamvu kwambiri. Njirayi, yomwe imadziwika kuti direct pumping, imaphatikizapo ulusi womwe umayamwa kuwala kwa pampu ndikuwutulutsa mwachindunji ngati laser output pa ma wavelength monga 1064nm, 1070nm, ndi 1080nm. Njirayi yopopera imagwiritsidwa ntchito kwambiri mu ma laser ofufuza komanso ma laser wamba amafakitale.
Diode ya laser yolumikizidwa ndi ulusi yokhala ndi 940nm ngati gwero la pampu ya laser ya fiber ya 1550nm
Mu gawo la ma laser a ulusi a 1550nm, ma laser olumikizidwa ndi ulusi okhala ndi kutalika kwa 940nm amagwiritsidwa ntchito kwambiri ngati magwero a mapampu. Ntchitoyi ndi yofunika kwambiri pa ntchito ya laser LiDAR.
Kugwiritsa Ntchito Kwapadera kwa Diode Yolumikizidwa ndi Laser ya Fiber yokhala ndi 790nm
Ma laser olumikizidwa ndi ulusi pa 790nm samangogwira ntchito ngati magwero a mapampu a ma laser a ulusi komanso amagwiritsidwanso ntchito mu ma laser olimba. Amagwiritsidwa ntchito makamaka ngati magwero a mapampu a ma laser omwe amagwira ntchito pafupi ndi kutalika kwa 1920nm, ndipo amagwiritsidwa ntchito kwambiri polimbana ndi kuwala kwa dzuwa.
MapulogalamuMa Laser Ophatikizidwa ndi Ulusi monga Magwero a Pampu a Laser Yolimba
Kwa ma laser a solid-state omwe amatulutsa pakati pa 355nm ndi 532nm, ma laser olumikizidwa ndi ulusi okhala ndi mafunde a 808nm, 880nm, 878.6nm, ndi 888nm ndi omwe amasankhidwa kwambiri. Izi zimagwiritsidwa ntchito kwambiri mu kafukufuku wasayansi komanso pakupanga ma laser a solid-state mu violet, blue, ndi green spectrum.
Kugwiritsa Ntchito Mwachindunji kwa Semiconductor Lasers
Ma laser opangidwa ndi Direct semiconductor laser akuphatikizapo direct output, lens coupling, circuit board integration, ndi system integration. Ma laser opangidwa ndi ulusi okhala ndi ma wavelength monga 450nm, 525nm, 650nm, 790nm, 808nm, ndi 915nm amagwiritsidwa ntchito m'njira zosiyanasiyana kuphatikizapo kuunikira, kuyang'anira njanji, kuwona makina, ndi machitidwe achitetezo.
Zofunikira pa gwero la mapampu a ma laser a fiber ndi ma laser olimba.
Kuti mumvetse bwino zofunikira pa gwero la pampu la ma fiber laser ndi ma solid-state laser, ndikofunikira kufufuza mwatsatanetsatane momwe ma laser awa amagwirira ntchito komanso udindo wa ma pomp sources pakugwira ntchito kwawo. Pano, tiwonjezera mwachidule koyamba kuti tifotokoze zovuta za makina opopera, mitundu ya ma pomp sources omwe amagwiritsidwa ntchito, komanso momwe amakhudzira magwiridwe antchito a laser. Kusankha ndi kasinthidwe ka ma pomp sources kumakhudza mwachindunji magwiridwe antchito a laser, mphamvu yotulutsa, ndi mtundu wa beam. Kulumikizana koyenera, kufananiza wavelength, ndi kasamalidwe ka kutentha ndikofunikira kwambiri pakukonza magwiridwe antchito ndikuwonjezera moyo wa laser. Kupita patsogolo kwa ukadaulo wa laser diode kukupitilizabe kukonza magwiridwe antchito ndi kudalirika kwa ma fiber ndi ma solid-state lasers, zomwe zimapangitsa kuti zikhale zosinthika komanso zotsika mtengo pa ntchito zosiyanasiyana.
- Zofunikira pa Magwero a Pampu ya Laser ya Ulusi
Ma Diode a Lasermonga Magwero a Pampu:Ma laser a fiber amagwiritsa ntchito ma laser diode makamaka ngati gwero la mapampu awo chifukwa cha kugwira ntchito bwino, kukula kwake kochepa, komanso kuthekera kopanga mafunde enieni a kuwala omwe amafanana ndi mayamwidwe a ulusi woponderezedwa. Kusankha mafunde a laser diode ndikofunikira kwambiri; mwachitsanzo, dopant yodziwika bwino mu ma laser a fiber ndi Ytterbium (Yb), yomwe ili ndi chiwopsezo chabwino kwambiri cha kuyamwa pafupifupi 976 nm. Chifukwa chake, ma laser diode omwe amatulutsa mafunde awa kapena pafupi ndi mafundewa ndi omwe amakondedwa popopera ma laser a Yb-doped fiber.
Kapangidwe ka Ulusi Wokhala ndi Zingwe Ziwiri:Kuti awonjezere mphamvu ya kuyamwa kwa kuwala kuchokera ku ma diode a laser a pampu, ma laser a fiber nthawi zambiri amagwiritsa ntchito kapangidwe ka ulusi wokhala ndi ma double-clad fiber. Pakati pa mtima pamakhala ndi laser medium yogwira ntchito (monga Yb), pomwe cladding layer yayikulu imatsogolera kuwala kwa pampu. Pakati pa mtima pamatenga kuwala kwa pampu ndikupanga laser, pomwe cladding imalola kuti pampu igwire ntchito ndi pakati, zomwe zimapangitsa kuti pakhale mphamvu zambiri.
Kufananiza kwa Wavelength ndi Kugwira Ntchito Mogwirizana: Kupompa bwino sikutanthauza kusankha ma diode a laser okhala ndi kutalika koyenera kwa nthawi komanso kukonza bwino kulumikizana pakati pa ma diode ndi ulusi. Izi zimaphatikizapo kulinganiza bwino ndikugwiritsa ntchito zida zowunikira monga magalasi ndi zolumikizira kuti zitsimikizire kuti kuwala kwa pampu kumalowetsedwa mu ulusi kapena cladding.
-Ma Laser OlimbaZofunikira pa Magwero a Pampu
Kupopera kwa Kuwala:Kupatula ma laser diode, ma solid-state lasers (kuphatikizapo ma bulk lasers monga Nd:YAG) amatha kupopedwa ndi kuwala pogwiritsa ntchito nyali zowala kapena nyali za arc. Nyali izi zimatulutsa kuwala kosiyanasiyana, komwe mbali yake imafanana ndi ma absorption bands a laser medium. Ngakhale kuti si yogwira ntchito bwino ngati laser diode pumping, njira iyi ingapereke mphamvu zambiri za pulse, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pakufunika mphamvu yayikulu.
Kapangidwe ka Magwero a Pampu:Kapangidwe ka gwero la pampu mu ma laser olimba kumatha kukhudza kwambiri magwiridwe antchito awo. Kupompa komaliza ndi kupompa mbali ndi machitidwe ofala. Kupompa komaliza, komwe kuwala kwa pampu kumayendetsedwa motsatira mzere wowala wa laser medium, kumapereka kulumikizana bwino pakati pa kuwala kwa pampu ndi njira ya laser, zomwe zimapangitsa kuti pakhale magwiridwe antchito apamwamba. Kupompa mbali, ngakhale kungakhale kopanda ntchito kwenikweni, ndikosavuta ndipo kungapereke mphamvu zambiri pa ndodo zazikulu kapena slabs.
Kusamalira Kutentha:Ma laser a fiber ndi solid-state onse amafunika kuyang'anira bwino kutentha kuti athetse kutentha komwe kumapangidwa ndi magwero a pampu. Mu ma laser a fiber, malo otambalala a ulusi amathandiza kuti kutentha kutayike. Mu ma laser a solid-state, makina oziziritsira (monga kuziziritsa madzi) ndi ofunikira kuti apitirize kugwira ntchito bwino ndikuletsa ma lens a kutentha kapena kuwonongeka kwa chipangizo cha laser.
