Eli nqaku likusa ekuqondeni ngokukhawuleza umatshini wokumakisha i-mopa fiber laser
1. Umahluko phakathi kwe-Q modulation kunye netekhnoloji ye-MOPA kwi-fiber lasers
Iintlobo ezimbini eziphambili ze-pulsed fiber lasers ezithengiswayo ngoku kwizicelo zokumakisha i-laser yi-Q-modulated technology kunye ne-MOPA technology, eyisakhiwo se-laser esiqulathe i-laser oscillator efakwe i-amplifier. Kwishishini, i-MOPA laser ibhekisa kwi-nanosecond pulsed fiber laser eyahlukileyo, "ekrelekrele" equlathe umthombo wembewu ye-laser seed eqhutywa yi-electrical pulse kunye ne-fiber amplifier. "Ubulumko" bayo bubonakala kakhulu kububanzi be-output pulse buhlengahlengiswa ngokuzimeleyo (uluhlu lunokufikelela kwi-2ns-500ns), kwaye i-repetition frequency inokufikelela kwi-megahertz. Isakhiwo sembewu ye-fiber laser seed source seed sifakwe kwi-fiber oscillation cavity loss modulator, ngokuguqula rhoqo i-optical loss kwi-resonant cavity ukuvelisa ububanzi be-pulse ethile ye-nanosecond pulse light output. Kule ngxaki idla ngokuba yingxaki, siza kwenza uhlalutyo olufutshane kwiinkalo ezintathu: isakhiwo sangaphakathi se-laser, iiparameter ze-optical output kunye neemeko zesicelo.
2. Ulwakhiwo lwangaphakathi lwelaser
Ulwakhiwo lwangaphakathi lwee-laser zefayibha ze-MOPA kunye nee-laser zefayibha ezi-Q-modulated lwahluke kakhulu kwindlela yokuvelisa isignali yokukhanya kwembewu ye-pulse, eveliswa yi-electric pulse eqhuba i-semiconductor laser chip, oko kukuthi isignali yokukhanya okuphumayo ilawulwa sisignali yombane eqhubayo, ngoko ke kukho ukuguquguquka okukhulu kokuvelisa iiparameter ezahlukeneyo ze-pulse (ububanzi be-pulse, i-repetition frequency, i-pulse waveform kunye namandla, njl.njl.). Isignali ye-pulsed seed optical ye-laser yefayibha e-Q-modulated iveliswa ngokunyusa okanye ukunciphisa ilahleko ye-optical rhoqo kwi-resonant cavity ukuvelisa i-pulsed optical output, elula kwisakhiwo kwaye inenzuzo ngakumbi kwixabiso. Nangona kunjalo, iiparameter ze-pulse zinqunyelwe kancinci zizixhobo ze-Q-modulated kunye nezinye iimpembelelo.
Umgaqo wolwakhiwo lwangaphakathi lwe-MOPA fiber laser kunye ne-Q-modulated fiber laser uboniswa ngokwesicwangciso ngolu hlobo lulandelayo.
3. Iiparameter zokukhanya eziphumayo
Ububanzi be-pulse ye-MOPA fiber laser buyakwazi ukulungelelaniswa ngokuzimeleyo. Ububanzi be-pulse ye-MOPA fiber laser bunokulungiseka ngokungacwangciswanga (ububanzi ukusuka kwi-2ns ukuya kwi-500 ns).
Okukhona ububanzi be-pulse buncipha, kokukhona indawo echaphazelekileyo bubushushu incinci kwaye kokukhona ukuchaneka kokucubungula kunokufumaneka.
Ububanzi be-pulse ye-Q-modulated fiber laser abulungiseki, kwaye ububanzi be-pulse buhlala buphuma ngexabiso elimiselweyo ukusuka kwi-80 ns ukuya kwi-140 ns. I-MOPA fiber laser inoluhlu olubanzi lwee-frequency eziphindaphindwayo. Ii-MOPA lasers zinokufikelela kwi-frequency output ephezulu ye-MHz. I-frequency ephezulu yokuphindaphinda ithetha ukusebenza kakuhle kokucubungula, kwaye i-MOPA inokugcina iimpawu zamandla aphezulu phantsi kweemeko ze-frequency ephezulu yokuphindaphinda. Ii-Q-modulated fiber lasers zinqunyelwe ziimeko zokusebenza ze-Q-switch kwaye zinoluhlu lwe-frequency output oluncinci, olufikelela kwi-~100 kHz kuphela kwii-frequency eziphezulu.
4. Imizekelo yesicelo
I-MOPA fiber laser ineeparameter ezininzi, ngoko ke ukongeza ekugubungeleni usetyenziso oluqhelekileyo lwe-nanosecond laser processing, ingasebenzisa nobubanzi bayo obuncinci be-pulse, i-re-frequency ephezulu, kunye namandla aphezulu ukuze ifezekise ezinye usetyenziso olulodwa lwe-processing ngokuchanekileyo. Umzekelo.
Usetyenziso lokuhluba umphezulu wephepha le-aluminium oxide elincinci
Ngoku iimveliso ze-elektroniki ezibhityileyo nezikhaphukhaphu, iifowuni ezininzi, iithebhulethi, iikhompyutha zisebenzisa i-aluminium oxide ebhityileyo njengeqokobhe lemveliso. Ukusetyenziswa kwe-Q-modulated laser kwi-thin aluminium plate marking conductive bit, kulula ukukhokelela kwi-deformation yezinto ezibonakalayo, umva wephakheji ye-convex, echaphazela ngqo imbonakalo yobuhle. Kwaye ukusetyenziswa kwe-MOPA laser pulse width parameters ezincinci, ezinokwenza ukuba izinto zingabi lula ukudeformation, umgca ophantsi ukwanobumhlophe obukhanyayo obuthambileyo. Oku kungenxa yokuba i-MOPA laser isebenzisa i-pulse width parameters encinci ingenza i-laser ihlale kwi-material ixesha elifutshane, kodwa ikwanawo namandla aphezulu okususa umaleko we-anode, ngoko ke kwi-thin aluminium oxide surface stripping anode processing, i-MOPA laser lukhetho olungcono.
Isicelo sokwenza mnyama kwe-aluminium eyosiweyo
Ukusebenzisa i-laser ukuphawula ilogo emnyama, inombolo yemodeli, umbhalo, njl.njl. kumphezulu wezinto ze-aluminium ezi-anodized, esi sicelo siye sasetyenziswa kancinci kancinci yi-Apple, i-Huawei, i-ZTE, i-Lenovo, i-Meizu kunye nabanye abavelisi be-elektroniki kwiminyaka emibini edlulileyo ukuphawula ilogo, inombolo yemodeli, njl.njl. ngamanqaku amnyama kwiqokobhe leemveliso ze-elektroniki. Kolu hlobo lwesicelo, yi-laser ye-MOPA kuphela enokuyicubungula okwangoku. Njengoko i-laser ye-MOPA inoluhlu olubanzi lobubanzi be-pulse kunye nokulungiswa kwe-pulse frequency, ukusetyenziswa kobubanzi be-pulse obuncinci, iiparameter ze-frequency ephezulu zinokuphawulwa kumphezulu wesiphumo esimnyama sezinto, ngokusebenzisa indibaniselwano eyahlukeneyo yeeparameter zinokuphawulwa ngesiphumo esahlukileyo se-grayscale.
Ukumakishwa kweLaser yoMbala
Ukumakishwa kwelaser yombala luhlobo olutsha lwenkqubo yokumakishwa kwelaser. Okwangoku, obu buchwephesha busetyenziswa okwethutyana kuphela ukumakishwa kwelaser ye-MOPA kwintsimbi engatyiwayo, i-chrome, i-titanium kunye nezinye izinto zesinyithi ezineepateni zombala. Xa udlala umbala kwizinto zentsimbi engatyiwayo, umqadi welaser unokulungiswa ukuze utshintshe umbala womphezulu wotshintsho lwezinto, ukuze ufumane isiphumo sokuhombisa semibala eyahlukeneyo, kushishino lweemveliso zentsimbi engatyiwayo, ungongeza umbala wepateni yokumakishwa, ungahlela iipateni ezahlukeneyo zombhalo njengoko ufuna, ezilula kwaye kulula ukuzisebenzisa: ukhuseleko lokusingqongileyo kunye nokungangcolisi; isantya sokumakishwa, kunokuphucula kakhulu ixabiso elongezelelweyo leemveliso zentsimbi engatyiwayo, kuphucule ukhuphiswano lwemarike lweemveliso zentsimbi engatyiwayo. Ukongeza ixabiso elongezelelweyo kwimveliso.
Ngokubanzi, ububanzi kunye nobuninzi be-MOPA fiber laser pulse buhlengahlengiswa ngokuzimeleyo, kunye noluhlu olukhulu lweeparamitha ezihlengahlengiswayo, ngoko ke ukucutshungulwa kwesiphumo esincinci, esiphantsi sobushushu, kwipleyiti encinci yokumakisha i-aluminium oxide, i-anodized aluminium emnyama, umbala wentsimbi engagqwaliyo, njl., iingenelo zokugqwesa, zinokufezekiswa isiphumo se-Q fiber laser azinakuphunyezwa. I-Q-modulated fiber laser ibonakaliswa ngokumakisha okunamandla, kwaye ineenzuzo ezithile ekucutshungulweni okunzulu kokukrola kweesinyithi, kodwa isiphumo sokumakisha sirhabaxa. Kwizicelo eziqhelekileyo zokumakisha, iimpawu eziphambili ze-MOPA pulsed fiber lasers xa kuthelekiswa ne-Q-modulated fiber lasers ziboniswe kwitheyibhile engasezantsi. Abasebenzisi banokukhetha i-laser efanelekileyo ngokweemfuno zokwenyani zezinto zokumakisha kunye neziphumo.
