I-MOPA ne-Q-switched fibre lasers
I-MOPA isifinyezo se-Master Oscillator Power Amplifier. I-laser ye-MOPA ibhekisela esakhiweni se-laser lapho i-laser oscillator neamplifier kukhishwa khona. Emhlabeni wezimboni, i-laser ye-MOPA isho i-laser “ehlakaniphe kakhulu” ye-nanosecond pulsed fiber ehlanganiswe umthombo wembewu we-laser semiconductor kanye ne-fiber amplifier, eshayelwa ama-pulses kagesi.
“Ubuhlakani” bayo bubonakala ngokuyinhloko ekhonweni layo lokuzilungisa ngokuzimela ububanzi be-pulse okukhiphayo (okusukela ku-2 kuye ku-500 ns), nemvamisa yokuphindaphinda efinyelela ku-1MHz. Isakhiwo somthombo wembewu ye-Q-switch i-fiber laser ifaka imoduli yokulahlekelwa ku-fiber oscillating cavity, ekhiqiza ukukhanya kwe-nanosecond pulse enobubanzi obunqunyiwe be-pulse ngokushintsha ngezikhathi ezithile ukulahlekelwa kokubona emgodini.
Ama-lasecond pulsed lasers asungulwe kahle ezisetshenziswa zezimboni ezifana nokumaka insimbi, ukushisela, ukuhlanza, nokusika. Njengezinhlobo ezimbili eziyinhloko zama-lasecond pulsed lasers, imuphi umehluko, izinzuzo, kanye nokubi kwesakhiwo se-MOPA vs isakhiwo se-Q-switch? Ukwenza lokhu kube lula ukuqonda sixoxa ngomehluko ngokuhlaziywa okulula kwesakhiwo sangaphakathi sama-lasers, amapharamitha okukhanya okukhiphayo, kanye nezimo zohlelo lokusebenza.
Ukuqhathaniswa kwesakhiwo sangaphakathi
Ukuqhathaniswa phakathi kwesakhiwo sangaphakathi nezimiso ze-MOPA fibre laser generator kanye ne-Q-switched fibre laser generator.
Umehluko omkhulu esakhiweni sangaphakathi phakathi kwe-MOPA fibre lasers kanye ne-Q-switched fibre lasers yindlela okukhiqizwa ngayo isignali ye-pulse seed optical.
I-MOPA fibre laser pulse seed optical signal ikhiqizwa i-electric pulse eshayela i-semiconductor laser chip. Ngamanye amazwi, isignali ye-optical okukhiphayo ishintshwa ngokushayela isignali kagesi, iyenze ikwazi ukukhiqiza imingcele ye-pulse eguquguqukayo (ububanzi be-pulse, imvamisa yokuphindaphinda, umumo we-pulse, namandla). Lokhu kuwusizo kakhulu uma umaka izinto ezibucayi njengamapulasitiki.
I-pulsed seed optical signal ye-Q-switched fiber i-laser ikhiqiza ukuphuma kokukhanya okududuzayo ngokukhuphula ngezikhathi ezithile noma ngokunciphisa ukulahleka kokubona kwe-resonator. Inesakhiwo esilula futhi ngakho-ke futhi inzuzo yentengo. Kodwa-ke, ngenxa yethonya lamadivayisi ashintshiwe nge-Q, imingcele ye-pulse inomkhawulo.
Ukuqhathaniswa kwemingcele ye-Optical
Ububanzi be-pulse okukhiphayo kwe-fiber laser ye-MOPA bungalungiseka ngokuzimela futhi bufundeka kalula (kusukela ku-2 ns kuya ku-500 ns). Ukunciphisa ububanzi be-pulse, indawo ethintekile ukushisa ibe yincane futhi iphakamisa ukunemba komshini. I-Q-switched fibre laser ayilungiseki futhi ngokuvamile ayishintshile ngenani elinqunyiwe elingu-80 kuya ku-140 ns.
I-MOPA fibre lasers inobubanzi obubanzi bokuphindaphinda imvamisa futhi ingafinyelela ukukhishwa kwefrikhwensi ephezulu okungu-1MHz. Imvamisa yokuphindaphinda ephezulu isho ukusebenza kahle okuphezulu kokucubungula, futhi i-MOPA ingagcina izici zamandla aphezulu ngaphansi kwezimo zokuphindaphinda okuphezulu. Ngenxa yemikhawulo yezimo zokusebenza ze-Q-switch, ama-laser e-fiber ashintshiwe e-Q anobubanzi obuncane bokuphuma kwemvamisa, afinyelela kuphela imvamisa engu-~100 kHz.
Ukuqhathanisa Isicelo
Umehluko ekusetshenzisweni okungenzeka kwemishini yokumaka i-MOPA laser kanye nemishini yokumaka ye-laser ye-Q-Switch ubalulekile.
Alumina Ishidi Elihlutshiwe Izicelo Zobuso
Njengamanje, inani elandayo lemikhiqizo emincane ye-elekthronikhi efana nomakhalekhukhwini, amaphilisi, namakhompyutha zisebenzisa i-aluminium oxide encane njengohlaka oluyinhloko, noma igobolondo, elihlanganisayo. Ukusebenzisa ama-lasers we-Q-switch epuleti le-aluminium elincanyana kungaholela kalula ekwakhiweni kwezinto noma kukhiqize “i-convex hull” ethinta ngqo ukubukeka kwayo. Ububanzi obuncane be-pulse bomaka be-laser be-MOPA buvumela izinguquko ezilula nezinembile kundaba, ukufiphaza kuthambile kakhulu, futhi noma yikuphi okumhlophe kuyakhanya. Lokhu kungenxa yokuthi umshini we-laser we-MOPA uyashesha ngenxa yobubanzi obuncane be-pulse obudinga isikhathi esincane ukuthintana nempahla. Ngaphezu kwalokho, i-laser enamandla amakhulu isusa ungqimba lwe-anode, ngakho-ke i-laser ye-MOPA iyisinqumo esingcono sokukhumula noma ukuguqula izindawo ezincane zamapuleti e-aluminium.
Ukumaka Okumnyama ku-Anodic Alumina
Ukusetshenziswa kwama-laser ezindaweni ezingaphezulu kwe-alumina ye-anodic kungakha amamaki amnyama, ihluzo, noma umbhalo. I-Apple, Huawei, Lenovo, kanye ne-Samsung basebenzise kakhulu ukumaka okumnyama ukuze bakhe izimpawu zokuthengisa, amalogo, nombhalo kumagobolondo wemikhiqizo yabo ye-elekthronikhi eminyakeni embalwa edlule. Amalaser e-MOPA kuphela angaqashwa kulolu hlobo lohlelo lokusebenza. Ububanzi be-pulse yabo obubanzi kanye nezigaba zefrikhwensi ye-pulse eziguquguqukayo ezivumela ububanzi obuncane be-pulse kanye nemingcele yefrikhwensi ephezulu, kungaba mnyama ngempumelelo indawo ebonakalayo. Inhlanganisela yepharamitha ehlukene ingaphinda inike amandla ama-shades ahlukene empunga.
I-Electronic, Semiconductor, kanye ne-ITO Precision Machining Applications
Embonini ye-elekthronikhi, ama-semiconductors, i-ITO, nezinye izinhlelo zokusebenza zomshini wokunemba zidinga ukusebenzisa ukumaka komugqa omuhle. Imigqa emihle kunzima ukuyifinyelela ngezakhiwo ze-laser ye-Q-switch, ngenxa yokungakwazi ukulungisa amapharamitha wobubanzi be-pulse. Imishini ye-laser ye-MOPA ingaguquguquka futhi ilungise ububanzi be-pulse kanye nemingcele yefrikhwensi, engakwazi ukudala imigqa emihle kakhulu kuphela, kodwa futhi imiphetho ebushelelezi.
Ngokungeziwe ezinhlelweni ezishiwo ngenhla, i-MOPA laser kanye nemishini ye-laser ye-Q-switch ingasetshenziswa ezinhlelweni eziningi. Ithebula elingezansi linikeza izibonelo ezijwayelekile zohlelo lokusebenza:
ngemva kokuqhathanisa lezi zinhlobo ezimbili kuyacaca ukuthi imishini yokumaka ye-MOPA fibre laser ingashintsha i-Q-switched fibre laser engravers ezinhlelweni eziningi. Eziningi zezinhlelo zokusebenza ezisezingeni eliphezulu, umqophi we-laser we-MOPA ifayibha inketho engcono kakhulu kunesistimu yokumaka i-fiber laser ye-Q eshintshiwe.

Isifinyezo
Ukufingqa, amalaza efiber e-MOPA anokufakwa kwepharamitha ye-laser ebanzi, ukulungiswa okuvumelana nezimo, kanye nebanga lohlelo lokusebenza eliphelele kune-Q-switched fiber lasers. Mayelana nemishini enamandla afanayo, i-Q-switched fiber lasers ishibhile ezicini ezimbalwa. Ngakho-ke, lezi zinhlobo ezimbili zemishini yelaser ye-nanosecond pulsed laser zinezindawo zokuthengisa ezihlukene, kuye ngokuthi zizosetshenziswa kuphi, ngezinga elingakanani, nokuthi imininingwane yomshini kufanele ibe yinkimbinkimbi kangakanani.
