Nekufambira mberi kwesainzi netekinoroji uye kuwedzera kweminda yakasiyana-siyana yekushandisa,laserTekinoroji yekugadzirisa iri kupinda zvishoma nezvishoma mumativi ese ehupenyu uye ichiva chishandiso chakakosha chekugadzirisa. Mukushandisa malaser,MOPA ine mwero we kilowattMalaser eMaster Oscillator Power-Amplifier anoshandiswa zvakanyanya muminda yakadai sekugadzirisa zvinhu uye kuyedza kwesainzi nekuda kwesimba rawo repamusoro, kupinda kwakasimba, uye kusimba kwekupisa kwakaderera. Iwo chishandiso chakakosha chekubatsira mabhizinesi kuvandudza mhando uye kuwedzera kugona. Chishandiso chakanakira kushanda zvakanaka. Asi nekuda kwesimba rayo guru, kuti tiwedzere kushanda zvakanaka kwelaser yeMOPA ine kilowatt-level, kusarudzwa kwezvishongedzo kwakakosha. Nekusarudza zvishongedzo zvelaser zvakakodzera chete ndipo patinogona kuva nechokwadi chekuti laser inogona kushanda zvakadzikama uye zvinobudirira uye zviri nani kusangana nezvinodiwa zvakasiyana-siyana zvekushandisa.
Simba rakasimba
Kugadzirwa kwakawanda kweMOPA ine kilowatt-level ine mashandiro epamusoro uye zviratidzo zvehunyanzvi
Kukwanisa kubereka zvakawanda zvakadzikamakilowatt-level single-modhi MOPA laserschiratidzo chakakosha cheMOPA laser R&D yekambani, kugadzira uye kugadzira. MAVEN parizvino ine mhando dzakasiyana dzemichina yekuchenesa fiber laser yeMOPA ine simba guru inogona kusangana nezvinodiwa zvekugadzirisa zvemashandisirwo akasiyana-siyana muzvikamu zvakasiyana.
Kuchinja-chinja kwesimba rinobuda kwemaawa makumi maviri nemana (24h) kuri pasi pe<3%
Hunhu hwedanda hunodzorwa
Danda reGaussian remhando imwe chete Danda rakatsetseka rine maitiro akawanda
Tekinoroji yekubatanidza masaini ekupedzisira, kugoverwa kwesimba kwakanyatsonaka uye kunonzwisisika, maitiro akasiyana ekugadzira coiling, uye single-mode high-power collimated isolator ine crystal inopenya zvakanyanya, nepo simba rekubuda richisvika 1000W, rinogonawo kuve nechokwadi chekuti Beam yakanaka.
Mumunda we fiber laser processing, kunyanya processing yelaser yeMOPA ine simba guru re nanosecond pulse fiber, nekuda kwesimba rayo repamusoro-soro, simba rayo guru rekurova kwemoyo uye frequency yakakwira, kusarudzwa kwezvishongedzo kwakakosha zvikuru. Zvishongedzo zvikuru zvinokanganisa mashandiro ekugadzirisa kwelaser yekurova kwemoyo ine simba guru zvinosanganisira Scanning galvanometer, focusing field mirror uye reflector.
Ungasarudza sei galvanometer yekuskena?
Chinangwa che tekinoroji yekuskena galvanometer ndechekupedzisa mabasa ekuskena anomhanya nekukasika uye nemazvo. Pane zvinhu zviviri zvikuru zvinosarudza. Chimwe isystem yekudzora inogona kusvika pakumhanya kukuru uye nemazvo, uye chimwe igalvanometer ine kukurumidza kupindura nekukurumidza. Chimiro chegalvanometer chine zvikamu zvitatu: reflector, motor uye drive card, pakati pazvo lens inokosha pakugadzikana kwekugadzirisa.
Lenzi yeGalvanometer nezvinhu zvinopa simba
Sisitimu yekutarisira kupisa yekuongorora galvanometerchinhu chakakoshawo pakuona kuti kugadzirisa kwenguva refu kwagara kwakasimba. Kusiyana kwekupisa kuchaita kuti galvanometer ifambe-fambe uye kuderedza kurongeka kwenzvimbo. Zvakajairika ndeizvi zvinotevera. Kuburikidza nekutonhodza mvura nekuparadza kupisa kunoshanda, kugadzikana kwekugadzirisa kwenguva refu kunogona kuvandudzwa ne30%.
Kukosha kwekupisa kwakajairika kwegalvanometer
Mudziyo wekutonhodza mvura unogona kubvisa kupisa zvinobudirira uye kuona kuti galvanometer inoshanda zvakanaka kwenguva refu. Nzira huru dzehunyanzvi ndeyekuwana nzvimbo yemvura inotonhodza isina kugadzikana zvakanyanya kuburikidza nekugadzirwa kwakanakisa kwenzira yemvura inotonhodza, uye kugadzira chimiro chekunze chinoshanda zvakanaka chemuchina wekuchinjana kupisa.
Muchirongwa cheMOPA pulse laser chine simba guru re kilowatt, tinokurudzira zvikuru kushandiswa kwema lenzi e quartz emhando yepamusoro uye masisitimu e galvanometer ane masisitimu ekutonhodza mvura.
Ungasarudza sei lenzi yekutarisa?
Lenzi yemunda inotarisa danda relaser rakaumbwa panzvimbo imwe, inowedzera simba relaser, uye inoshandisa simba rakawanda relaser kuita mabasa akasiyana-siyana akadai sekucheka, kuisa mamaki, kusanganisa, kuchenesa uye kugadzirisa pamusoro.
Zvinhu zvikuru zvinokanganisa kunaka kwekugadzirisa uye mhedzisiro yelenzi yemunda izvinhu zviri mulenzi yemunda uye kukwirira kweringi yeadapta. Zvinhu zvikuru zvelenzi yemunda igirazi nequartz. Musiyano uripo pakati pezviviri uri mumhedzisiro yelenzi yekupisa pasimba guru. Mushure mekunge lenzi yemunda inoramba ichivhenekerwa nemwaranzi yelaser kwenguva yakareba, inogadzira kushanduka kwekushisa nekuda kwekuwedzera kwekupisa, izvo zvinozokonzera transmission optics. Refractive index yechinhu uye kutungamira kwe reflective optical element kuchinja, uye thermal lens effect ichakanganisa maitiro elaser nenzvimbo ye focus mushure me focus, izvo zvichakanganisa zvakanyanya mhedzisiro yekugadzirisa. Quartz ine low thermal expansion coefficient uye high transmittance, zvichiita kuti ive sarudzo iri nani yezvinhu zvelenzi yemunda ine simba guru. Kana zvichidikanwa, module yekutonhodza mvura inofanira kuwedzerwa.
Mhete yeadapta yekufananidza lenzi yemunda negalvanometer chinhu chakakosha chinokanganisa michina nekugadzirisa. Kureba kwakakodzera kwemhete yeadapta kunogona kudzivirira nzvimbo yekudzokera kwelenzi yemunda uye kuve nechokwadi chekuti fomati yekugadzirisa iri kushanda. Kana yakakwira zvakanyanya kana kuti yakaderera zvakanyanya, inokonzera matambudziko anoenderana.
MumaMOPA pulse laser systems ane simba guru re kilowatts, tinokurudzira zvikuru kushandiswa kwemagirazi emhando yepamusoro e quartz ane ma modules ekutonhodza mvura uye ring ye field mirror adapter yakatsaurirwa ine urefu hwakakodzera.
Nzira yekufananidza ma lenses anoratidzira?
Basa guru rema lenzi anoratidzira chiedza muchimiro chenzira ye optical nderekushandura divi renzira ye optical. Kusarudza ma lenzi anoratidzira emhando yepamusoro uye nzira dzakajairwa dzekuisa zvinogona kuita basa guru mune mamwe mashandisirwo akakosha, asi ma lenzi emhando isina kunaka uye nzira dzisina musoro dzekuisa dzichakonzerawo mubvunzo mutsva. Hunhu hwe lenzi hunoenderana ne wavelength nesimba re laser. Substrate inowanzo gadzirwa ne fused quartz kana crystalline silicon. Firimu re reflective re laser rinowanzo gadzirwa ne sirivha kana transparent dielectric film, ine reflectivity yakakwira, low absorption rate uye laser resistance. Hunhu hwe high damage threshold.
Chiratidziro cheplane chakakodzera hachizokanganisi kunaka kwefocus, asi pakushandisa chaiko, reflection plane inogona kukanganiswa nekuda kwezvinhu zvakaita sekusunga sikuruu, zvakafanana negirazi rakatenderera. Kukanganiswa uku kunonyanya kukanganisa kunaka kwefocus spot, zvichikonzera astigmatism yakaderera uye mamwe astigmatism yakaderera. Kusagadzikana kunodzivirira focus spot kusvika pamuganho we diffraction, zvichikanganisa kunaka kwekugadzirisa uye mhedzisiro.
MumaMOPA pulse laser systems ane simba repamusoro-soro, tinokurudzira zvikuru kushandiswa kwema quartz reflectors emhando yepamusoro uye nzira dzakakodzera dzekuisa kuti ma lens agare nesimba pasina kuchinja.
