M'zaka zaposachedwapa, ntchito pulsed CHIKWANGWANI lasers m'munda wa chodetsa laser zakula mofulumira, mwa zimene ntchito m'minda ya zamagetsi 3C mankhwala, makina, chakudya, ma CD, etc. akhala kwambiri.
Pakadali pano, mitundu ya ma pulsed fiber lasers omwe amagwiritsidwa ntchito poyika chizindikiro pamsika makamaka amaphatikiza ukadaulo wa Q-switched ndiukadaulo wa MOPA.Laser ya MOPA (Master Oscillator Power-Amplifier) imatanthawuza mawonekedwe a laser momwe cholumikizira cha laser ndi amplifier chimatsitsidwa.M'makampani, laser ya MOPA imatanthawuza "wanzeru" wapadera komanso "wanzeru" wa nanosecond pulse fiber laser wopangidwa ndi semiconductor laser seed source yoyendetsedwa ndi pulses yamagetsi ndi amplifier fiber."Nzeru" zake zimawonetsedwa makamaka pakutulutsa kwamphamvu kwapang'onopang'ono komwe kumasinthika (kusiyana kwa 2ns-500ns), ndipo ma frequency obwereza amatha kukhala okwera ngati megahertz.Kapangidwe ka gwero la mbewu ya Q-switched fiber laser ndikuyika modulitsa wotayika mu fiber oscillator patsekeke, yomwe imatulutsa kuwala kwa nanosecond pulse ndi m'lifupi mwake kugunda mwakusintha nthawi ndi nthawi kutayika kwa kuwala kwapabowo.
Mapangidwe amkati a laser
Kusiyanitsa kwamkati pakati pa MOPA CHIKWANGWANI laser ndi Q-Switched CHIKWANGWANI laser makamaka lagona m'badwo osiyanasiyana njira kugunda mbewu kuwala chizindikiro.Chizindikiro cha MOPA fiber laser pulse seed optical chimapangidwa ndi chipangizo chamagetsi chamagetsi choyendetsa semiconductor laser chip, ndiye kuti, chizindikiro cha kuwala chimasinthidwa ndi chizindikiro chamagetsi choyendetsa, choncho chimakhala champhamvu kwambiri popanga magawo osiyanasiyana a pulse (pulse m'lifupi, kubwerezabwereza pafupipafupi). , pulse waveform ndi mphamvu, etc.) Kusinthasintha.Chizindikiro cha pulse seed optical cha Q-switched fiber laser chimapanga kutulutsa kowala kokulirapo powonjezera nthawi ndi nthawi kapena kuchepetsa kutayika kwa kuwala m'matumbo a resonant, ndi kapangidwe kosavuta komanso mwayi wamtengo.Komabe, chifukwa cha chikoka cha zida zosinthira Q, magawo a pulse ali ndi zoletsa zina.
Linanena bungwe kuwala magawo
MOPA CHIKWANGWANI laser linanena bungwe zimachitika m'lifupi ndi paokha chosinthika.Kugunda kwamphamvu kwa MOPA CHIKWANGWANI laser ali ndi tunability iliyonse (osiyana 2ns ~ 500 ns).Kuchepetsa kuchuluka kwa kugunda, kumachepetsa malo omwe amakhudzidwa ndi kutentha, komanso kulondola kwapang'onopang'ono kumatha kupezeka.Kutulutsa kwamphamvu kwa Q-switched fiber laser sikusinthika, ndipo kuchuluka kwa kugunda nthawi zambiri kumakhala kokhazikika pamtengo wokhazikika pakati pa 80 ns ndi 140 ns.MOPA CHIKWANGWANI laser ali lonse kubwerezabwereza osiyanasiyana osiyanasiyana.Kubwereza pafupipafupi kwa laser ya MOPA kumatha kufikira ma frequency apamwamba a MHz.Kubwereza pafupipafupi kumatanthawuza kuti magwiridwe antchito apamwamba kwambiri, ndipo MOPA imatha kukhalabe ndi mawonekedwe apamwamba kwambiri amphamvu pansi pazikhalidwe zapamwamba zobwerezabwereza.Laser ya Q-switched fiber imachepetsedwa ndi momwe zimagwirira ntchito pa switch ya Q, kotero kuti ma frequency otuluka amakhala ochepa, ndipo ma frequency apamwamba amatha kufika ~ 100 kHz.
Zochitika zantchito
MOPA CHIKWANGWANI laser ali lonse parameter kusintha osiyanasiyana.Choncho, kuwonjezera pa kuphimba ntchito processing wa ochiritsira nanosecond lasers, angagwiritsenso ntchito yake yapadera yopapatiza zimachitika m'lifupi, mkulu kubwerezabwereza pafupipafupi, ndi mkulu nsonga mphamvu kukwaniritsa zina mwapadera mwatsatanetsatane processing ntchito.monga:
1. Kugwiritsa ntchito kuchotsa pamwamba pa pepala la aluminium oxide
Masiku ano zinthu zamagetsi zikucheperachepera komanso zopepuka.Mafoni ambiri, mapiritsi, ndi makompyuta amagwiritsa ntchito aluminiyamu oxide woonda komanso wopepuka ngati chipolopolo.Mukamagwiritsa ntchito Q-switched laser kuti muyike malo opangira pa mbale yopyapyala ya aluminiyamu, ndikosavuta kupangitsa kuti zinthu zisinthe, zomwe zimapangitsa kuti "convex hulls" kumbuyo, kukhudza mwachindunji kukongola kwa mawonekedwe.Kugwiritsa ntchito magawo ang'onoang'ono a MOPA laser pulse m'lifupi mwake kungapangitse kuti zinthuzo zisakhale zophweka kufooketsa, ndipo mthunzi wake ndi wosakhwima komanso wowala.Izi ndichifukwa choti laser ya MOPA imagwiritsa ntchito kagawo kakang'ono kakang'ono kamene kamapangitsa kuti laser ikhalebe pazachifupi, ndipo imakhala ndi mphamvu zokwanira kuchotsa anode wosanjikiza, kotero pakukonza kuvula anode pamwamba pa aluminium oxide woonda. mbale, MOPA Lasers ndi kusankha bwino.
2.Anodized aluminiyamu blackening ntchito
Pogwiritsa ntchito ma lasers kuti alembe zizindikiro zakuda, zitsanzo, malemba, ndi zina zotero pamtunda wa aluminiyamu ya anodized, m'malo mwa inkjet yachikhalidwe ndi teknoloji ya silika, yakhala ikugwiritsidwa ntchito kwambiri pazipolopolo zazinthu zamagetsi zamagetsi.
Chifukwa MOPA pulsed CHIKWANGWANI laser ali lonse zimachitika m'lifupi ndi kubwerezabwereza pafupipafupi kusintha osiyanasiyana, ntchito yopapatiza kugunda m'lifupi ndi mkulu pafupipafupi magawo akhoza chizindikiro pamwamba zinthu ndi zotsatira zakuda.Kuphatikizika kosiyana kwa magawo kumathanso kuyika milingo yotuwa.zotsatira.
Choncho, ali zambiri selectivity kwa ndondomeko zotsatira za wakuda osiyana ndi dzanja kumverera, ndipo ndi yokonda kuwala gwero kwa blackening anodized zotayidwa pa msika.Kuyika chizindikiro kumachitika m'njira ziwiri: madontho ndi mphamvu yadontho.Posintha kachulukidwe ka madontho, zotsatira zosiyanasiyana za imvi zimatha kutsatiridwa, ndipo zithunzi zosinthidwa makonda ndi zaluso zamunthu zimatha kulembedwa pamwamba pa aluminiyamu ya anodized.
3.Color laser cholembera
Pakugwiritsa ntchito utoto wachitsulo chosapanga dzimbiri, laser imayenera kugwira ntchito ndi zing'onozing'ono komanso zapakatikati zogundana komanso ma frequency apamwamba.Kusintha kwamtundu kumakhudzidwa makamaka ndi pafupipafupi komanso mphamvu.Kusiyana kwa mitundu iyi kumakhudzidwa makamaka ndi mphamvu imodzi ya laser yokha komanso kuphatikizika kwa malo ake pazinthuzo.Chifukwa kugunda m'lifupi ndi mafupipafupi a MOPA laser ndi paokha chosinthika, kusintha mmodzi wa iwo sangakhudze magawo ena.Amathandizana wina ndi mnzake kuti akwaniritse zotheka zosiyanasiyana, zomwe sizingachitike ndi laser Q-switched.Muzogwiritsa ntchito, posintha kuchuluka kwa kugunda, ma frequency, mphamvu, liwiro, njira yodzaza, malo odzaza ndi magawo ena, kuvomereza ndikuphatikiza magawo osiyanasiyana, mutha kuyika zambiri zamitundu yake, mitundu yolemera komanso yosakhwima.Pazitsulo zazitsulo zosapanga dzimbiri, zida zamankhwala ndi ntchito zamanja, ma logo okongola kapena mawonekedwe amatha kulembedwa kuti azikongoletsa zokongola.
Ambiri, zimachitika m'lifupi ndi pafupipafupi MOPA CHIKWANGWANI laser ndi paokha chosinthika, ndi kusintha chizindikiro osiyanasiyana lalikulu, kotero processing ndi zabwino, zotsatira matenthedwe ndi otsika, ndipo ali ndi ubwino chapadera mu zotayidwa okusayidi pepala chodetsa, anodized zotayidwa. zakuda, ndi zitsulo zosapanga dzimbiri mitundu.Zindikirani momwe Q-switched fiber laser silingakwaniritsidwe The Q-switched fiber laser imadziwika ndi mphamvu yamphamvu yolemba, yomwe ili ndi zabwino zina pakukonza zitsulo zozama, koma kuyika chizindikiro kumakhala kovutirapo.Pazolemba zodziwika bwino, ma laser a MOPA amafananizidwa ndi ma laser a Q-switched fiber, ndipo mawonekedwe awo akulu akuwonetsedwa patebulo lotsatirali.Ogwiritsa ntchito amatha kusankha laser yoyenera malinga ndi zosowa zenizeni za zida zolembera ndi zotsatira.
MOPA CHIKWANGWANI laser zimachitika m'lifupi ndi pafupipafupi ndi paokha chosinthika, ndi kusintha chizindikiro osiyanasiyana lalikulu, kotero processing ndi bwino, zotsatira matenthedwe ndi otsika, ndipo ali ndi ubwino chapadera mu zotayidwa okusayidi pepala chodetsa, anodized zotayidwa blackening, zosapanga dzimbiri zitsulo mitundu, ndi kuwotcherera pepala zitsulo.Zotsatira zomwe Q-switched fiber laser sizingakwaniritse.Laser ya Q-switched fiber imadziwika ndi mphamvu yolemba yolimba, yomwe ili ndi zabwino zina pakukonza zitsulo zozama, koma kuyika kwake kumakhala kovutirapo.
Ambiri, MOPA CHIKWANGWANI lasers pafupifupi m'malo Q-switched CHIKWANGWANI lasers mu laser mkulu-mapeto chodetsa ndi kuwotcherera ntchito.M'tsogolomu, chitukuko cha MOPA CHIKWANGWANI lasers adzatenga yopapatiza zimachitika m'lifupi ndi mafunde apamwamba monga malangizo, ndipo nthawi yomweyo kuguba ku mphamvu apamwamba ndi mphamvu apamwamba, kupitiriza kukwaniritsa zofunika zatsopano laser zinthu processing chabwino, ndi kupitiriza kukhala monga laser derusting ndi lidar.Ndi madera ena atsopano ogwiritsira ntchito.
