Iyini i-fiber laser?
I-fiber laser iwuhlobo lwelaser yesimo esiqinile lapho i-revenue medium iwumucu wengilazi ohlanganiswe nezinto ezingavamile zomhlaba. Lokhu kuvumela ukusebenza kahle kokuguqulwa kwe-photoelectric okuphezulu, isakhiwo esilula, nekhwalithi enhle ye-beam.
Lolu hlelo selube yinsakavukela ekuthuthukisweni kobuchwepheshe be-laser kanye nasekusetshenzisweni kwezimboni. Ezinye zezizathu zalokhu zihlanganisa i-fiber optical footprint encane, okusho ukuthi inokusebenza okubanzi kanye nezinga eliphezulu lokusetshenziswa ezinkambini zokukhiqiza nokucubungula ezansi nomfula. Esinye isizathu ukuguquguquka okuphezulu kwe-fiber laser, okuvumela ukusetshenziswa kwayo ezinhlelweni eziningi. Ukwengeza, ithuthukise ikhwalithi ye-beam, engakhulisa umphumela wokunciphisa izindleko kanye nokwenza ngcono ukusebenza kahle kwamabhizinisi okukhiqiza.
Izici ze-fiber laser
- Ukukhanya okuphezulu, i-laser yemodi eyodwa, ezuzwe ngokumpompa umthombo wokukhanya we-LD wamandla aphezulu, nokukhanya kancane usuka ku-spectrum yokumuncwa kwezinto zomhlaba ezingavamile ngokusebenzisa isakhiwo sefayibha egqoke kabili.
- Idizayini encane futhi eguquguqukayo, ukusebenza kahle kokuguqulwa okuphezulu, kanye nekhono lokusebenza ngaphansi kwezimo ezinzima ngenxa yesistimu yayo yokupholisa ephumelelayo.
- Ukukhiqizwa kwemishayo yekhwalithi enhle ngekhono eliphezulu lokuguqulwa kanye nomkhawulo ophansi.
- Ukukhishwa kwe-laser kubhendi engu-0.38-4um, kutholwa ngokusebenzisa izakhi zomhlaba eziyivelakancane ezihlukile.
- Ukukhetha okulula nokuguqulekayo kwe-wavelength, kanye nebanga lokushuna elibanzi.
- Ukuhlanganisa okuhle kanye nezinga eliphezulu lokuhambisana nezinhlelo ezikhona zokuxhumana optical.
- Imishini ye-Fiber optic kanye nemicu yokubona, enciphisa kakhulu izindleko zesakhiwo.
Ukwakheka nomgomo
Njengezinye izinhlobo ze-laser, i-fiber laser inezingxenye ezintathu: i-resonant medium, umthombo wepompo, kanye ne-resonant cavity. Ukuze uthole indlela yokuzuza, i-fiber laser isebenzisa imicu esebenzayo ehlanganiswe nezinto ezingavamile zomhlaba emnyombweni wayo. Ngokuvamile, i-laser semiconductor isetshenziswa njengomthombo wepompo. I-resonant cavity ngokuvamile yakhiwa izibuko, ubuso bokuphela kwe-fiber, izibuko ze-fiber loop, noma ama-fiber gratings.
Inqubo ethile yokusebenza imi kanje: Esimeni sokusebenza, i-fiber esebenzayo (i-fibre yenzuzo) imunca amandla anikezwa umthombo wepompo. Khona-ke, i-laser ephumayo ikhuliswa yi-cavity ye-resonant eyakhiwe i-fiber esebenzayo kanye ne-fiber grating.
Umthombo wembewu
Okwaziwa nangokuthi umthombo wesignali, umthombo wembewu uyinto yokukhulisa imisebe ohlelweni lokukhulisa i-laser. Lapha, i-laser enikeza isignali yamandla aphansi isetshenziswa “njengembewu” ukuvumela uhlelo lokukhulisa ukhuliswe ngokuvumelana nesimo sale “mbewu.”
I-fiber optical esebenzayo
I-fibre esebenzayo isetshenziswa njengendlela yokuthola, nomsebenzi wokuzuza ukukhuliswa ngokuguqula amandla asuke ekukhanyeni kwepompo aye ekukhanyeni okuyisignali.
I-passive optical fiber
I-passive optical fiber ikakhulukazi ibona umsebenzi wokudlulisa ukukhanya futhi ayihlanganyeli ekuguquleni ubude be-wavelength. Kukhona ikakhulukazi ama-fiber gratings ezinhlelweni ze-fiber laser, ezinamafayibha ahambisanayo ahambisanayo kuma-fiber isolator kanye ne-passive multimode imicu yokuhambisa amandla amakhulu ezingxenyeni zokudlulisa amandla e-laser.
Njengamanje, leyo mikhiqizo yefiber optical fibre evela kubahlinzeki basekhaya icishe ikwazi ukuhlangabezana nezidingo zokukhiqiza, ngenani elincane kuphela le-passive optical fiber esetshenziswa emikhiqizweni yamandla aphezulu lisasebenzisa i-optical fiber engenisiwe.
I-Fiber laser optics
Umthombo wepompo
Umthombo wephampu ungasetshenziswa njengomthombo wokukhanya oqondile ukuze ukhiphe ukukhanya kwe-laser kuma-lasers we-industrial semiconductor. Ukwengeza, ingasetshenziswa njengomthombo wokukhanya wephampu ukuze inikeze amandla aphezulu, ukukhanya okuphezulu kwepompo yama-fiber lasers.
Isihlanganisi sepompo
Amalaser avela emithonjeni yephampu eminingi angahlanganiswa futhi afakwe ku-fiber optical ukuze kuzuzwe ukuphuma kwelaser yepompo yamandla aphezulu.
Isihlanganisi samandla
Isihlanganisi samandla singakwazi ukuphakamisa amandla avela kumamojula we-laser we-fiber enamandla amaningi. Kuphinde kube yidivayisi ewumongo lapho udala okukhiphayo kwe-laser ye-multi-mode.
I-fiber grating
I-fiber grating i-diffraction grating eyakhiwa ngokushintshashintsha ngezikhathi ezithile inkomba ye-refractive ye-fiber core ngendlela ethile. I-fiber grating ingeyedivayisi yesihlungi engenzi lutho futhi iyingxenye edingekayo kunoma iyiphi i-resonator. Iphinde inqume ubude begagasi obuphumayo kanye nomkhawulokudonsa we-laser futhi ingalawula imodi ye-laser nekhwalithi ye-beam.
Ikhanda le-laser
Ikhanda le-laser liyingxenye ebalulekile yokubona ibanga elide le-laser yamandla aphezulu, okukhiphayo okuguquguqukayo endaweni yohlelo lokusebenza. Iphinde ihambisane nesistimu yokwenza imishini, okusho ukuthi i-laser ekhiqizwe i-laser ingadluliselwa ezintweni zokucubungula ukuze kuqedelwe uhlelo lokusebenza lwe-laser machining.
Isolator
I-isolator ivikela i-laser futhi ivimbele ukukhanya okubuyayo ekulimazeni noma yiziphi ezinye izingxenye ze-optical.
stripper
I-stripper ingakwazi ukuhlubula ngempumelelo ukukhanya okugqunyiwe ku-laser, ivikele noma imaphi amadivayisi ahlobene, futhi ithuthukise ikhwalithi ye-laser beam ephumayo. I-acousto-optic modulator isetshenziswa kakhulu ngaphakathi kwe-resonator ukuze kulungiswe i-laser pulse edingekayo ngobuchwepheshe bokushintshashintsha kwe-radio frequency drive. Ingenye yezingxenye eziyinhloko ze-Q-switched pulse fiber laser.
Isifanisi sephethini
Isifanisi sephethini iyidivayisi eyinhloko esetshenziselwa ukuxhuma izinhlobo ezimbili ezihlukene zamafiber okubona ukuze kuncishiswe ukulahleka koxhumano nokuthuthukisa ukufanisa inkambu yemodi ye-laser.
Izinhlobo nokusetshenziswa
Ngokuya ngemodi yokusebenza, izinhlobo ezimbili ezivame ukusetshenziswa kakhulu zama-fiber lasers yilaser eqhubekayo kanye ne-pulsed laser. Lezi zingasetshenziswa ukusika, ukushisela, ukuqopha, ukumaka, ukuhlanza, nezinye izimo.
I-laser eqhubekayo
I-laser eqhubekayo ikhipha i-beam yokukhanya eqhubekayo, enamandla amakhulu angu-120KW. Isetshenziselwa ukusika, ukushisela, ukubhula nokumba. I-semi-continuous laser (QCW) isashayeka kodwa inobubanzi be-pulse ende namandla aphezulu angu-23KW, esetshenziselwa ukusika, ukushisela i-arc, ukubhoboza, ukubhula, nokucisha insimbi (ukuthuthukisa i-ductility yensimbi kanye nokunciphisa ukumelana ne-DC). Ilungele kakhulu ukufaka esikhundleni samalaser e-YAG ampontshwa isibani endaweni yokushisela, kanye nokushisela ngomthungo kanye nezinhlelo zokusebenza zokubhoboza. Kukhona ukugqagqana okuthile ekusebenzeni nge-laser eqhubekayo.
I-laser ye-pulsed
Ama-laser ane-pulsed angahlukaniswa abe ama-nanosecond, picosecond, nama-laser we-femtosecond pulsed. Ilaser ye-nanosecond enobubanzi be-pulse ende inamandla aphakeme angu-1MW futhi isetshenziselwa ukubhala, ukuqopha, ukubhoboza, ukwelashwa kwendawo, ukucisha, nokumaka. I-laser ye-nanosecond enobubanzi obufushane be-pulse yokuqedela okuncane isetshenziselwa ukucisha, i-silicon wafer, nokusika ingilazi.
I-picosecond laser enobubanzi be-pulse efinyelela ezingeni le-piccosecond inamandla aphezulu angaphezu kuka-10MW futhi isetshenziselwa ukusika mnyama, isafire nengilazi, nokusika i-photovoltaic ne-OLED. I-laser ye-femtosecond enobubanzi be-pulse kufika ezingeni le-femtosecond inamandla aphakeme angaphezu kuka-29MW, asetshenziselwa ukusika insimbi yeshidi, ukubhoboza, ukucutshungulwa okunembayo okuphezulu, nokuhlinzwa kwamehlo.
