Incazelo ye-Laser Diode ehlanganiswe ne-Fiber, Isimiso Sokusebenza, kanye ne-Wavelength Ejwayelekile
I-fiber-coupled laser diode iyithuluzi le-semiconductor elikhiqiza ukukhanya okuhlangene, okube sekugxilwe futhi kuqondiswe kahle ukuze kuhlanganiswe nekhebula le-fiber optic. Isimiso esiyinhloko sihilela ukusebenzisa ugesi wamanje ukuvuselela i-diode, ukudala ama-photon ngokukhishwa okushukunyisiwe. Lawa ma-photon akhuliswa ngaphakathi kwe-diode, akhiqize umsebe we-laser. Ngokugxila ngokucophelela nokuqondanisa, lo msebe we-laser uqondiswa enkabeni yekhebula le-fiber optic, lapho udluliselwa khona ngokulahlekelwa okuncane ngokubonakaliswa kwangaphakathi okuphelele.
Ububanzi Bobude Bamagagasi
Ubude besikhathi obujwayelekile be-module ye-laser diode ehlanganiswe ne-fiber bungahluka kakhulu kuye ngokuthi isetshenziswa kanjani. Ngokuvamile, lawa madivayisi angamboza ububanzi be-wavelengths, okuhlanganisa:
I-Spectrum Yokukhanya Ebonakalayo:Kusukela cishe ku-400 nm (violet) kuya ku-700 nm (red). Lokhu kuvame ukusetshenziswa ezinhlelweni ezidinga ukukhanya okubonakalayo ukuze kukhanye, kuboniswe, noma kuzwakale.
I-Near-Infrared (NIR):Isukela cishe ku-700 nm kuya ku-2500 nm. Ama-wavelength e-NIR avame ukusetshenziswa kwezokuxhumana, izinhlelo zokusebenza zezokwelapha, kanye nezinqubo ezahlukahlukene zezimboni.

Izidingo zomthombo wephampu wama-laser e-fiber kanye nama-laser e-solid-state.
Ukuze uthole ukuqonda okuningiliziwe ngezidingo zomthombo wephampu yama-fiber lasers nama-solid-state lasers, kubalulekile ukuhlolisisa imininingwane yokuthi la ma-laser asebenza kanjani kanye nendima yemithombo yephampu ekusebenzeni kwawo. Lapha, sizokwandisa umbono wokuqala ukuze simboze ubunzima bezindlela zokupompa, izinhlobo zemithombo yephampu esetshenziswayo, kanye nomthelela wazo ekusebenzeni kwe-laser. Ukukhetha kanye nokucushwa kwemithombo yephampu kuthinta ngqo ukusebenza kahle kwe-laser, amandla okukhipha, kanye nekhwalithi ye-beam. Ukuxhumanisa okusebenzayo, ukufanisa ubude be-wavelength, kanye nokuphathwa kokushisa kubalulekile ekwenzeni ngcono ukusebenza kanye nokwandisa isikhathi sokuphila kwe-laser. Intuthuko kubuchwepheshe be-laser diode iyaqhubeka nokuthuthukisa ukusebenza kanye nokuthembeka kwama-fiber lasers kanye nama-solid-state lasers, okwenza abe nezimo eziningi futhi abe nezindleko ezinhlelweni eziningi ezahlukene.
- Izidingo Zomthombo Wephampu Ye-Fiber Lasers
Ama-Diode e-Lasernjengemithombo yephampu:Ama-laser e-fibre asebenzisa kakhulu ama-laser diode njengomthombo wawo wokupompa ngenxa yokusebenza kahle kwawo, usayizi omncane, kanye nekhono lokukhiqiza ubude be-wavelength obuthile bokukhanya obuhambisana ne-spectrum yokumunca ye-fibre ehlanganisiwe. Ukukhetha ubude be-wavelength ye-laser diode kubalulekile; isibonelo, i-dopant evamile kuma-laser e-fibre yi-Ytterbium (Yb), ene-peak yokumunca efanelekile engaba ngu-976 nm. Ngakho-ke, ama-laser diode akhipha kule wavelength noma eduze kwale wavelength ayathandwa kakhulu ekupompeni ama-laser e-fibre ehlanganisiwe yi-Yb.
Umklamo Wefayibha Enezimbobo Ezimbili:Ukuze kwandiswe ukusebenza kahle kokumuncwa kokukhanya okuvela kuma-diode e-laser ephampu, ama-laser e-fiber avame ukusebenzisa umklamo we-fiber ombozwe kabili. Ingaphakathi elingaphakathi lifakwe i-laser medium esebenzayo (isb., Yb), kuyilapho ungqimba lwangaphandle olukhulu, olumbozwe luqondisa ukukhanya kwephampu. Ingaphakathi limunca ukukhanya kwephampu futhi likhiqize isenzo se-laser, kuyilapho i-cladding ivumela inani elikhulu kakhulu lokukhanya kwephampu ukuthi lisebenzisane nengaphakathi, okuthuthukisa ukusebenza kahle.
Ukufanisa Ubude Bamagagasi Nokusebenza Kahle Kokuxhumanisa: Ukupompa okuphumelelayo akudingi nje ukukhetha ama-diode e-laser anobude obufanele kodwa futhi nokuthuthukisa ukusebenza kahle kokuxhumanisa phakathi kwama-diode ne-fiber. Lokhu kuhilela ukuvumelanisa ngokucophelela kanye nokusetshenziswa kwezingxenye ezibonakalayo ezifana nama-lens nama-couplers ukuqinisekisa ukuthi ukukhanya okuphezulu kwephampu kufakwa ku-fiber core noma i-cladding.
-Ama-Laser Esimo EsiqinileIzidingo Zomthombo Wephampu
Ukupompa Okubonakalayo:Ngaphandle kwama-laser diode, ama-laser aqinile (kufaka phakathi ama-laser amakhulu njenge-Nd:YAG) angapompelwa ngokukhanya ngezibani ze-flash noma izibani ze-arc. Lezi zibani zikhipha ububanzi bokukhanya, ingxenye yazo ehambisana nama-absorption bands e-laser medium. Nakuba ingasebenzi kahle njengokupompelwa kwe-laser diode, le ndlela inganikeza amandla aphezulu kakhulu e-pulse, okwenza ifaneleke ezinhlelweni ezidinga amandla aphezulu.
Ukucushwa Komthombo Wephampu:Ukucushwa komthombo wephampu kuma-laser aqinile kungathinta kakhulu ukusebenza kwawo. Ukupompa kokugcina kanye nokupompa eceleni kuyizinto ezivamile. Ukupompa kokugcina, lapho ukukhanya kwephampu kuqondiswa khona nge-optical axis ye-laser medium, kunikeza ukufana okungcono phakathi kokukhanya kwephampu kanye nemodi ye-laser, okuholela ekusebenzeni kahle okuphezulu. Ukupompa eceleni, yize kungenzeka kungasebenzi kahle, kulula futhi kunganikeza amandla aphezulu ezindongeni noma kuma-slabs amakhulu.
Ukuphathwa Kokushisa:Kokubili ama-laser e-fiber kanye ne-solid-state adinga ukuphathwa kahle kokushisa ukuze aphathe ukushisa okukhiqizwa yimithombo yephampu. Kuma-laser e-fiber, indawo ende yobuso be-fiber iyasiza ekushabalaleni kokushisa. Kuma-laser e-solid-state, izinhlelo zokupholisa (ezifana nokupholisa amanzi) ziyadingeka ukuze kugcinwe ukusebenza okuzinzile futhi kuvinjelwe ukulensiwa kokushisa noma ukulimala kwe-medium ye-laser.
