Mumakore achangopfuura, kushandiswa kwepulsed fiber lasers mumunda wekumaka laser kwakakura nekukurumidza, pakati peiyo mashandisirwo muminda yemagetsi 3C zvigadzirwa, michina, chikafu, kurongedza, nezvimwe zvave zvakanyanya.
Parizvino, mhando dze pulsed fiber lasers dzinoshandiswa mukumaka laser pamusika dzinonyanya kusanganisira Q-switched tekinoroji uye MOPA tekinoroji.MOPA (Master Oscillator Power-Amplifier) laser inoreva chimiro chelaser umo laser oscillator uye amplifier zvinodonhedzwa.Muindasitiri iyi, MOPA laser inoreva yakasarudzika uye yakawanda "yakangwara" nanosecond pulse fiber laser inoumbwa ne semiconductor laser mbeu sosi inofambiswa nemagetsi pulses uye fiber amplifier.Iyo "njere" yaro inonyanya kuratidzwa mune inobuda pulse upamhi inozvimiririra inogadziriswa (renji 2ns-500ns), uye iyo yekudzokorora frequency inogona kunge yakakwira semegahertz.Iyo mhodzi sosi chimiro cheQ-switched fiber laser ndeyekuisa yekurasikirwa modulator mufiber oscillator cavity, iyo inoburitsa nanosecond pulse mwenje kubuda neimwe pulse hupamhi nekugara ichigadzirisa kurasikirwa kwemaziso mugomba.
Chimiro chemukati che laser
Musiyano wemukati wechimiro pakati peMOPA faibha laser uye Q-switched fiber laser inonyanya kuve mune dzakasiyana chizvarwa nzira dze pulse mbeu chiedza chiratidzo.Iyo MOPA fiber laser pulse seed optical chiratidzo inogadzirwa nemagetsi pulse kutyaira semiconductor laser chip, ndiko kuti, iyo inobuda optical siginecha inogadziriswa neyekutyaira yemagetsi chiratidzo, saka yakasimba kwazvo pakugadzira akasiyana pulse paramita (pulse width, kudzokorora frequency. , pulse waveform uye simba, nezvimwewo) Flexibility.Iyo pulse seed optical chiratidzo cheQ-switched fiber laser inogadzira pulsed light kubuda nekuwedzera nguva nenguva kana kuderedza kurasikirwa kwemaziso mumhango inonzwika, ine chimiro chakareruka uye mukana wemutengo.Nekudaro, nekuda kwepesvedzero yeQ-switching zvishandiso, iyo pulse paramita ine zvimwe zvinorambidzwa.
Output optical parameters
MOPA faibha laser inobuda pulse upamhi inozvimiririra inogadziriswa.Iyo pulse yakafara yeMOPA fiber laser ine chero tunability (renji 2ns ~ 500 ns).Iyo yakatetepa iyo pulse hupamhi, iyo idiki iyo inopisa-yakakanganiswa nzvimbo, uye yakakwirira kugadzirisa iko kurongeka kunogona kuwanikwa.Iyo inobuda pulse hupamhi hweiyo Q-switched fiber laser haigadzirike, uye pulse hupamhi hunowanzogara pane imwe yakatemerwa kukosha pakati pe80 ns uye 140 ns.MOPA faibha laser ine yakafara kudzokorora frequency renji.Iyo re-frequency yeMOPA laser inogona kusvika kune yakakwira frequency kubuda kweMHz.Yakakwira yekudzokorora frequency inoreva kukwirira kwekugadzirisa, uye MOPA inogona kuramba ichichengetedza yakakwirira yepamusoro peak masimba pasi peyakanyanya kudzokorora frequency mamiriro.Iyo Q-switched fiber laser inoganhurwa nemamiriro ekushanda eiyo Q switch, saka iyo inobuda frequency renji idiki, uye yakakwirira frequency inogona kusvika ~ 100 kHz.
Mamiriro ekushandisa
MOPA faibha laser ine yakafara parameter kugadzirisa renji.Naizvozvo, pamusoro pekuvharidzira mashandisirwo eakajairwa nanosecond lasers, inogona zvakare kushandisa yakasarudzika yakatetepa pulse hupamhi, yakakwirira yekudzokorora frequency, uye yakakwirira peak simba kuti uwane imwe yakasarudzika chaiyo yekugadzirisa maapplication.zvakaita se:
1.Kushandiswa kwekubvisa pamusoro pealuminium oxide sheet
Mazuva ano zvigadzirwa zvemagetsi zviri kuita zvitete uye zvakareruka.Mazhinji nharembozha, mahwendefa, uye makomputa anoshandisa yakatetepa uye yakareruka aluminium oxide segoko rechigadzirwa.Paunenge uchishandisa Q-switched laser kumaka conductive zvinzvimbo pane yakaonda aluminium ndiro, zviri nyore kukonzera deformation yechinhu, zvichikonzera "convex hulls" kumusana, zvichikanganisa zvakananga aesthetics yechitarisiko.Iko kushandiswa kweMOPA laser's diki pulse upamhi ma paramita anogona kuita kuti zvinhu zvisave nyore kukanganisa, uye shading yakanyanya kutetepa uye kupenya.Izvi zvinodaro nekuti iyo MOPA laser inoshandisa diki pulse hupamhi paramende kuita kuti laser igare pane zvinhu ipfupi, uye ine yakakwira yakakwana simba rekubvisa anode layer, saka pakugadziriswa kwekubvisa anode pamusoro peiyo yakatetepa aluminium oxide. ndiro, MOPA Lasers isarudzo iri nani.
2.Anodized aluminium blackening application
Kushandisa lasers kumaka nhema trademark, modhi, zvinyorwa, nezvimwewo pamusoro peanodized aruminiyamu zvinhu, pachinzvimbo chechinyakare inkjet uye silk screen tekinoroji, yakashandiswa zvakanyanya pamateko emagetsi edhijitari zvigadzirwa.
Nekuti iyo MOPA pulsed fiber laser ine yakafara pulse hupamhi uye yekudzokorora frequency kurongeka renji, kushandiswa kweyakatetepa pulse hupamhi uye yakakwirira frequency paramita inogona kumaka pamusoro pechinhu chine dema mhedzisiro.Musanganiswa wakasiyana wemaparamendi unogona zvakare kumaka akasiyana grey mazinga.effect.
Naizvozvo, ine yakanyanya kusarudzwa kwemaitiro ehutema hwakasiyana uye kunzwa kwemaoko, uye ndiyo yakasarudzika mwenje sosi yekudzima anodized aluminium pamusika.Kumaka kunoitwa nenzira mbiri: dot modhi uye yakagadziriswa dot simba.Nekugadzirisa kuwanda kwemadoti, akasiyana greyscale mhedzisiro inogona kutevedzerwa, uye yakagadziridzwa mafoto uye hunyanzvi hwemunhu anogona kumakwa pamusoro peanodized aluminium zvinhu.
3.Color laser marking
Mune simbi isina tsvina yemavara application, iyo laser inodiwa kushanda nediki uye yepakati pulse hupamhi uye yakakwirira frequency.Kuchinja kwemavara kunonyanya kukanganiswa nehuwandu uye simba.Musiyano mune aya mavara unonyanya kukanganiswa neiyo imwechete pulse simba re laser pachayo uye kuwanda kwehuwandu hwenzvimbo yayo pane izvo zvinhu.Nekuti iyo pulse hupamhi uye frequency yeMOPA laser inogadziriswa yakazvimiririra, kugadzirisa imwe yacho hakuzokanganisa mamwe ma paramita.Ivo vanobatirana mumwe nemumwe kuti vawane akasiyana mikana, iyo isingagone kuwanikwa neQ-switched laser.Mumashandisirwo anoshanda, nekugadzirisa iyo pulse hupamhi, frequency, simba, kumhanya, nzira yekuzadza, kuzadza nzvimbo uye mamwe ma paramita, kubvumidza uye kusanganisa akasiyana ma parameter, unogona kumaka mamwe emavara ayo, akapfuma uye akapfava mavara.Patafura yesimbi isina tsvina, midziyo yekurapa uye mabasa emaoko, mavara anoyevedza kana mapatani anogona kumakwa kuti atambe yakanaka yekushongedza maitiro.
Kazhinji, iyo pulse hupamhi uye frequency yeMOPA fiber laser inochinjika yakazvimiririra, uye gadziriso parameter yakakura, saka kugadzirisa kwacho kwakanaka, iyo yekupisa mhedzisiro yakadzikira, uye ine mabhenefiti akatanhamara mualuminium oxide sheet yekumaka, anodized aluminium. blackening, uye Stainless simbi coloring.Ziva mhedzisiro iyo Q-inochinja fiber laser haigone kuwana Iyo Q-inochinja fiber laser inoratidzirwa nesimba rakasimba rekumaka, iro rine mamwe mabhenefiti mukudzika kwakadzika kwekunyora kugadzirwa kwesimbi, asi iyo yekumaka mhedzisiro ine hutsinye.Mumashandisirwo akajairika ekumaka, MOPA pulsed fiber lasers inofananidzwa neQ-switched fiber lasers, uye iwo makuru maficha anoratidzwa patafura inotevera.Vashandisi vanogona kusarudza iyo chaiyo laser zvinoenderana nezvinodiwa chaizvo zvekumaka zvinhu uye mhedzisiro.
MOPA fiber laser pulse hupamhi uye frequency inochinjika yakazvimiririra, uye gadziriso yeparameter yakakura, saka kugadzirisa kwacho kwakanaka, iyo yekupisa mhedzisiro yakadzikira, uye ine mabhenefiti akatanhamara mualuminium oxide sheet yekumaka, anodized aluminium blackening, simbi isina tsvina. uye sheet metal welding.Mhedzisiro iyo Q-inochinja fiber laser haigone kuwana.Iyo Q-switched fiber laser inoratidzirwa nesimba rakasimba rekumaka, iro rine mamwe mabhenefiti mukudzika kwakadzika kwekunyora kugadzirwa kwesimbi, asi iyo yekumaka mhedzisiro ine hutsinye.
Kazhinji, MOPA faibha lasers inogona kutsiva Q-switched faibha lasers mune laser yepamusoro-yekupedzisira yekumaka uye welding application.Mune ramangwana, kuvandudzwa kweMOPA fiber lasers kunotora yakatetepa pulse upamhi uye yakakwirira frequency senge nzira, uye panguva imwe chete ichifora ichienda kusimba repamusoro uye simba repamusoro, ramba uchizadzisa zvinodiwa zvitsva zvelaser zvinhu zvakanaka kugadzirisa, uye ramba uchiita. gadzira senge laser derusting uye lidar.Uye dzimwe nzvimbo itsva dzekushandisa.
