Mu myaka yashize, ikoreshwa rya fibre fibre fibre murwego rwo kwerekana ibimenyetso bya laser ryateye imbere byihuse, muribyo bikorwa mubijyanye nibicuruzwa bya elegitoroniki 3C, imashini, ibiryo, gupakira, nibindi byagutse cyane.
Kugeza ubu, ubwoko bwa fibre fibre ikoreshwa mu kwerekana ibimenyetso bya laser ku isoko ahanini harimo Q-yahinduwe na tekinoroji ya MOPA.MOPA (Master Oscillator Power-Amplifier) laser bivuga imiterere ya laser aho oscillator ya laser na amplifier bifatirwa.Mu nganda, laser ya MOPA bivuga lazeri idasanzwe kandi "ifite ubwenge" ya nanosecond pulse fibre igizwe na semiconductor laser isoko yimbuto itwarwa na pulses yamashanyarazi hamwe na fibre amplifier."Ubwenge" bwayo bugaragarira cyane cyane mubisohoka bya pulse ubugari bushobora kwigenga (intera 2ns-500ns), kandi inshuro zisubiramo zishobora kuba ndende nka megahertz.Imiterere yimbuto yimiterere ya Q-ihinduranya fibre ya laser ni ugushyiramo modulator igihombo mumyanya ya fibre oscillator, itanga urumuri rwa nanosekond pulse yumucyo hamwe nubugari runaka bwa pulse muguhindura igihombo cya optique mumyanya.
Imiterere y'imbere ya laser
Itandukaniro ryimiterere yimbere hagati ya MOPA fibre laser na Q-yahinduwe fibre laser cyane cyane muburyo butandukanye bwibisekuruza byurumuri rwimbuto.Ikimenyetso cya MOPA fibre laser pulse imbuto ya optique ikorwa numuriro wamashanyarazi utwara semiconductor laser chip, ni ukuvuga, ibimenyetso bya optique bisohoka byahinduwe nicyapa cyamashanyarazi, bityo kirakomeye cyane kubyara ibipimo bitandukanye (ubugari bwa pulse, inshuro zisubiramo , pulse waveform nimbaraga, nibindi) Guhinduka.Imbuto yimbuto ya optique ya Q-yahinduwe fibre laser itanga urumuri rwumucyo mugihe cyo kongera cyangwa kugabanya igihombo cya optique mumyanya ya resonant, hamwe nuburyo bworoshye hamwe nigiciro cyibiciro.Ariko, kubera ingaruka za Q-guhinduranya ibikoresho, ibipimo bya pulse bifite aho bigarukira.
Ibisohoka optique
MOPA fibre laser isohoka pulse ubugari irashobora kwigenga.Ubugari bwa pulse ya MOPA fibre laser ifite uburinganire ubwo aribwo bwose (intera 2ns ～ 500 ns).Kugabanya ubugari bwa pulse, ntoya ya zone yibasiwe nubushyuhe, hamwe nukuri gutunganijwe neza birashobora kuboneka.Ibisohoka bisohora ubugari bwa Q-yahinduwe fibre laser ntishobora guhinduka, kandi ubugari bwimpiswi burigihe burigihe kumurongo runaka uhamye hagati ya 80 ns na 140 ns.MOPA fibre laser ifite intera yagutse yo gusubiramo inshuro.Re-frequency ya MOPA laser irashobora kugera kumurongo mwinshi wa MHz.Inshuro nyinshi zisubiramo bisobanura gutunganya neza, kandi MOPA irashobora kugumana imbaraga zo hejuru ziranga ibihe byinshi byo gusubiramo.Q-ihinduranya fibre laser igarukira kubikorwa byakazi bya Q ihinduka, bityo ibisohoka inshuro zingana, kandi numurongo mwinshi ushobora kugera ~ 100 kHz.
Ikoreshwa rya porogaramu
MOPA fibre laser ifite intera nini yo guhindura ibipimo.Kubwibyo, usibye gutwikira porogaramu zikoreshwa za lazeri zisanzwe za nanosekond, irashobora kandi gukoresha ubugari bwayo budasanzwe bwagutse, inshuro nyinshi zisubiramo, hamwe nimbaraga zo hejuru kugirango igere kubikorwa byihariye byo gutunganya neza.nka:
1.Gusaba kwambura ubuso urupapuro rwa aluminium oxyde
Ibicuruzwa bya elegitoroniki byubu biragenda byoroha.Terefone nyinshi zigendanwa, tableti, na mudasobwa zikoresha aside ya aluminiyumu yoroheje kandi yoroheje nkigicuruzwa cyibicuruzwa.Iyo ukoresheje Q-yahinduye lazeri kugirango ushireho umwanya uyobora kuri plaque ya aluminiyumu yoroheje, biroroshye gutera ihinduka ryibikoresho, bikavamo "convex hulls" inyuma, bikagira ingaruka kuburyo bwiza bwo kugaragara.Gukoresha MOPA laser ntoya ntoya ya pulse yubugari irashobora gutuma ibikoresho bitoroha guhinduka, kandi igicucu kiroroshye kandi cyiza.Ni ukubera ko lazeri ya MOPA ikoresha ibipimo bito byubugari bwa pulse kugirango laser igume kubintu bigufi, kandi ifite imbaraga nyinshi zihagije zo gukuraho anode, bityo rero mugutunganya kwambura anode hejuru ya oxyde ya aluminiyumu yoroheje. isahani, MOPA Lasers ni amahitamo meza.
2.Imikorere ya aluminiyumu yirabura
Ukoresheje lazeri kugirango ushireho ibimenyetso biranga umukara, icyitegererezo, inyandiko, nibindi hejuru yibikoresho bya aluminiyumu anodize, aho gukoresha tekinoroji ya inkjet gakondo hamwe na tekinoroji ya silike, yakoreshejwe cyane mugikonoshwa cyibikoresho bya elegitoroniki.
Kuberako MOPA pulsed fibre fibre ifite ubugari bwagutse no gusubiramo inshuro zingana, ikoreshwa ryubugari bwimisemburo migari hamwe nibipimo byinshi bishobora kwerekana hejuru yibintu bifite ingaruka zumukara.Guhuza ibice bitandukanye bishobora kandi kwerekana urwego rwimyenda itandukanye.Ingaruka.
Kubwibyo, ifite amahitamo menshi yingaruka zuburyo bwumukara no kumva amaboko atandukanye, kandi nisoko yumucyo watoranijwe wo kwirabura aluminiyumu anodize kumasoko.Kumenyekanisha bikorwa muburyo bubiri: uburyo bwadomo nimbaraga zahinduwe.Muguhindura ubucucike bwududomo, ingaruka zinyuranye zirashobora kwigana, kandi amafoto yihariye hamwe nubukorikori bwihariye bishobora gushyirwaho hejuru yibikoresho bya aluminiyumu.
3. Ikimenyetso cyamabara
Mugukoresha ibara ryicyuma, lazeri irasabwa gukorana nubugari buto kandi buciriritse bugari hamwe ninshuro nyinshi.Guhindura ibara byibasiwe cyane ninshuro nimbaraga.Itandukaniro ryaya mabara ryibasiwe cyane ningufu imwe ya pulse ya laser ubwayo nigipimo cyo guhuzagurika cyumwanya wacyo kubintu.Kuberako ubugari bwa pulse ninshuro ya laser ya MOPA birashobora kwigenga byigenga, guhindura kimwe muribi ntabwo bizagira ingaruka kubindi bipimo.Bafatanya hagati yabo kugirango bagere kubintu bitandukanye bishoboka, bidashobora kugerwaho na Q yahinduwe na laser.Mubikorwa bifatika, muguhindura ubugari bwa pulse, inshuro, imbaraga, umuvuduko, uburyo bwo kuzuza, kuzuza umwanya hamwe nibindi bipimo, kwemerera no guhuza ibipimo bitandukanye, urashobora gushiraho ibimenyetso byinshi byamabara yabyo, amabara akungahaye kandi yoroshye.Ibikoresho byo kumeza bidafite ibyuma, ibikoresho byubuvuzi nubukorikori, ibirango byiza cyangwa ibishushanyo birashobora gushyirwaho kugirango bikine neza.
Muri rusange, ubugari bwa pulse ninshuro ya fibre fibre ya MOPA birashobora guhinduka byigenga, kandi ibipimo byo guhinduranya ni binini, bityo gutunganya ni byiza, ingaruka zumuriro ni muke, kandi ifite ibyiza byingenzi mumashusho ya aluminium oxyde, aluminium anodize umwijima, hamwe n'amabara y'icyuma.Menya ingaruka Q-ihinduranya fibre laser idashobora kugera kuri Q-ihinduranya fibre laser irangwa nimbaraga zikomeye zo kuranga, zifite inyungu zimwe na zimwe mugutunganya ibishushanyo mbonera byimbitse, ariko ingaruka zo gushiraho zirakabije.Mubisanzwe biranga porogaramu, MOPA pulsed fibre lazeri igereranwa na Q-yahinduwe fibre, kandi ibyingenzi byingenzi byerekanwe kumeza ikurikira.Abakoresha barashobora guhitamo lazeri iburyo ukurikije ibikenewe byukuri byo gushiraho ibikoresho n'ingaruka.
MOPA fibre laser pulse ubugari ninshuro birashobora guhinduka byigenga, kandi ibipimo byo guhinduranya ni binini, bityo gutunganya ni byiza, ingaruka zumuriro ni muke, kandi ifite ibyiza byingenzi mumashusho ya aluminium oxyde, ibara ryirabura rya aluminiyumu, amabara yicyuma, no gusudira ibyuma.Ingaruka Q-yahinduye fibre laser ntishobora kugeraho.Q-yahinduwe fibre laser irangwa nimbaraga zikomeye zo gushiraho ikimenyetso, zifite ibyiza bimwe na bimwe mugutunganya ibishushanyo byimbitse byo gutunganya ibyuma, ariko ingaruka zo kwerekana ibimenyetso birakaze.
Muri rusange, MOPA fibre fibre irashobora gusimbuza Q-ihinduranya fibre ya lazeri murwego rwohejuru rwerekana ibimenyetso no gusudira.Mu bihe biri imbere, iterambere rya fibre fibre ya MOPA rizatwara ubugari bwimyanya ndangagitsina hamwe ninshuro nyinshi nkicyerekezo, kandi icyarimwe kigenda kigana imbaraga nyinshi nimbaraga nyinshi, komeza wuzuze ibisabwa bishya byo gutunganya ibikoresho bya laser, kandi bikomeze kwiteza imbere nka laser derusting na lidar.Nibindi bice bishya byo gusaba.
