I-Fiber laser cutting kanye Nezokwelapha

I-fiber laser cutting kanye nomuthi, i-fiber laser cutting machine i-doped fiber ngokwayo njengento esebenzayo, kanye nomshini wokusika we-fiber laser ngokwawo, kodwa futhi udlala indima ye-wave wave solid-state laser.I-resonator, iqukethe into esebenzayo, umthombo wepompo izingxenye ezintathu eziyisisekelo.Eminyakeni yamuva nje, ama-fiber lasers emikhakheni yezimboni ngaphezu kwezicelo eziningi, kanye nokuthandwa okwandayo emkhakheni wezokwelapha.

I-Fiber Technology Center, i-University of Sydney, e-Australia (OFT C) ka-Stuart Jackson yathi: "Umshini wokusika i-fiber laser wokuhlinzwa, kubalulekile ukuhlanganisa ama-lasers, ukunakekelwa okuncane, ukusebenza kahle okuphezulu okuphezulu kanye nezindawo ezinhle ezishisayo ze-fiber laser.ukubenza bafaneleke ikakhulukazi izinhlelo zokusebenza zokuhlinza ngoba zisebenzisa i-diode-pumped, ngakho-ke ihlangene kakhulu.Umumo wefiber kune-solid-state laser material uphakeme ngoba wehlise isidingo sefayibha yokudlulisela eyengeziwe, ngaleyo ndlela wehlise izindleko futhi wehlise Ubunkimbinkimbi bohlelo”.

Umshini wokusika i-Fiber laser ngo-1963 ngu-Elias Spritzer owasungulwa.Ngaphambi kokuthi ekugcineni ungene ekusetshenzisweni kwezohwebo, ngemuva cishe kweminyaka emibili yesikhathi sokuthuthukiswa.Ekuqaleni, ukusetshenziswa kwe-laser yemodi eyodwa ye-diode kwampontshwa, amashumi emisebe yamamililitha kuphela.Kodwa inabasebenzisi abaningi abasakhanga ngenxa yenzuzo yabo ephezulu, ingenza ukusebenza okuningi okuqhubekayo kwemodi eyodwa ye-ion yomhlaba engavamile, okuyi-crystal laser ayikwazi ukuzuzwa.Ngo-1990, ama-fiber lasers ukuze afinyelele isigaba sokuphuma kwe-leap-watt, kwase-ke, abika amandla aphumayo e-erbium-doped fiber laser akhuphuke ngo-4 W, lokhu kuthuthukiswa namuhla sibona amandla angu-10 W kanye nesisekelo esiphezulu se-fiber lasers yemodi eyodwa.

Emshinini wokusika we-fiber laser, i-fiber ngokwayo isebenza njenge-resonant cavity.Lawa madivayisi ngokuvamile ahlanganisa i-erbium doped single-mode core ytterbium (noma izinhlanganisela zayo), noma i-elementi yomhlaba eyivelakancane.Amandla asuka emthonjeni wokukhanya okuqinile, ahlanganiswa nokumbozwa kwefayibha, bese kuthi emnyombweni, iphampu iphefumule ama-athomu.Emkhakheni wezokwelapha, ubude begagasi budingeka kakhulu: 1.3μm ibhendi yokuthwebula, 1.5μm (isiqongo sokumunca amanzi) -4μm ibhande lokuhlinzwa, elisukela kububanzi bamandla amamililitha kuya kwangaphezu kuka-100 W.

UJackson uthe: “Ukusetshenziswa kwama-laser e-CW, izinhlelo zokusebenza ze-biomedical, ikakhulukazi noma yimaphi ama-laser anamandla we-CW, angazuza kumshini wokusika we-fiber laser ngomshini wokusika we-fiber laser kunikeza ukusebenza kahle okuphezulu, ububanzi bokushuna, kanye nakho konke okukhiphayo.ububanzi bamandla bunenzuzo yekhwalithi engcono ye-beam, ikakhulukazi evelele;ukuze i-fiber lasers ihluke ezinhlelweni zezokwelapha iqhubeke nokukhula.“
