Izidingo zomthombo wepompo wama-laser we-fiber kanye nama-laser wesifunda esiqinile.
Ukuze uthole ukuqonda okuningiliziwe kwezidingo zomthombo wephampu zama-laser wefayibha namalaser esifunda esiqinile, kubalulekile ukuhlola imininingwane yokuthi la ma-lasers asebenza kanjani kanye nendima yemithombo yephampu ekusebenzeni kwawo. Lapha, sizonweba ekubukeni kokuqala ukuze simboze ubunkimbinkimbi bezindlela zokumpompa, izinhlobo zemithombo yephampu esetshenziswayo, nomthelela wazo ekusebenzeni kwelaser. Ukukhetha nokucushwa kwemithombo yephampu kuthinta ngqo ukusebenza kahle kwe-laser, amandla okukhiphayo, kanye nekhwalithi ye-beam. Ukuhlanganisa okusebenzayo, ukufaniswa kwe-wavelength, nokuphatha okushisayo kubalulekile ekuthuthukiseni ukusebenza nokwelula isikhathi sempilo ye-laser. Intuthuko kubuchwepheshe be-laser diode iyaqhubeka nokuthuthukisa ukusebenza nokuthembeka kwawo womabili ama-laser we-fiber kanye ne-solid-state, okuwenza abe nezinto ezihlukahlukene futhi angabizi kakhulu ezinhlotsheni eziningi zezinhlelo zokusebenza.
- Izidingo zomthombo we-Fiber Lasers Pump
Ama-Laser Diodesnjengemithombo Yephampu:Ama-fiber lasers asebenzisa kakhulukazi i-laser diode njengomthombo wawo wepompo ngenxa yokusebenza kahle kwawo, usayizi ohlangene, kanye nekhono lokukhiqiza ubude obuthile bokukhanya obufana ne-spectrum yokumuncwa kwefayibha ehlanganisiwe. Ukukhethwa kwe-laser diode wavelength kubalulekile; isibonelo, i-dopant evamile kuma-laser e-fiber yi-Ytterbium (Yb), enenani eliphezulu lokumuncwa elizungeze u-976 nm. Ngakho-ke, ama-laser diode aphumayo kule wavelength noma eduze nayo ancanyelwa ukumpompa ama-laser efiber e-Yb-doped.
Idizayini ye-Double-Clad Fiber:Ukuze kwandiswe ukusebenza kahle kokumuncwa kokukhanya kuma-laser diode epompo, ama-fiber lasers avame ukusebenzisa idizayini yefayibha egqoke kabili. Ingaphakathi elingaphakathi lifakwe i-laser medium esebenzayo (isb, Yb), kuyilapho ungqimba olungaphandle, olukhudlwana luqondisa ukukhanya kwepompo. I-core imunca ukukhanya kwephampu futhi ikhiqize isenzo se-laser, kuyilapho ukuvala kuvumela inani elibaluleke kakhulu lokukhanya kwepompo ukuthi lihlanganyele nomongo, okuthuthukisa ukusebenza kahle.
Ukufanisa I-Wavelength kanye Nokubambisana Ngokuphumelelayo: Ukupompa okuphumelelayo akudingi kuphela ukukhetha ama-laser diode anobude beza obufanele kodwa futhi nokuthuthukisa ukusebenza kahle kokuhlanganisa phakathi kwama-diode nefiber. Lokhu kuhilela ukuqondanisa okucophelela kanye nokusetshenziswa kwezingxenye ezibonakalayo ezifana namalensi namabhangqa ukuze kuqinisekiswe ukukhanya kwepompo okukhulu kujovwe kumongo wefayibha noma ukuvala.
-I-Solid-State LasersIzidingo zomthombo wepompo
I-Optical Pumping:Ngaphandle kwama-laser diode, ama-laser-state aqinile (okuhlanganisa ama-laser amaningi afana no-Nd:YAG) angampontshwa ngokubonayo ngamalambu akhanyayo noma ama-arc. Lezi zibani zikhipha i-spectrum ebanzi yokukhanya, ingxenye yakho efana namabhendi okumunca we-laser medium. Nakuba ingasebenzi kahle kakhulu kunokumpompa i-laser diode, le ndlela inganikeza amandla okushaya kwenhliziyo aphezulu kakhulu, iyenze ifanelekele izinhlelo zokusebenza ezidinga amandla aphezulu aphezulu.
Ukucushwa komthombo wephampu:Ukucushwa komthombo wephampu kumalaser wesimo esiqinile kungaba nomthelela omkhulu ekusebenzeni kwawo. I-end-pump kanye ne-side-pumping yizimo ezivamile. Ukupompa kokuphela, lapho ukukhanya kwepompo kuqondiswe ku-eksisi yokubona ye-laser medium, kunikeza ukugqagqana okungcono phakathi kokukhanya kwepompo nemodi ye-laser, okuholela ekusebenzeni kahle okuphezulu. Ukupompa emaceleni, nakuba kungasebenzi kahle kangako, kulula futhi kunganikeza amandla amaningi aphezulu ezindongeni ezinobubanzi obukhulu noma ama-slabs.
Ukuphatha Okushisayo:Kokubili ama-laser efiber kanye ne-solid state adinga ukuphathwa okushisayo okusebenzayo ukuze kuphathe ukushisa okukhiqizwa imithombo yephampu. Kuma-laser e-fiber, indawo enwetshiwe ye-fiber isiza ekuqedeni ukushisa. Kuma-lasers wesimo esiqinile, amasistimu okupholisa (okufana nokupholisa amanzi) ayadingeka ukuze kugcinwe ukusebenza okuzinzile nokuvimbela i-lensing eshisayo noma ukulimala kwe-laser medium.
