Laser processing yakajairika muhupenyu hwedu hwezuva nezuva uye vazhinji vedu tinonyatsoziva nayo. Iwe unogona kazhinji kunzwa kuti mazwi nanosecond laser, picosecond laser, femtosecond laser. Vese ndeve ultrafast laser. Asi unoziva here kuti ungavasiyanisa sei?
Kutanga, ngatione kuti izvi "zvechipiri" zvinorevei.
1 nanosecond = 10
-9 chepiri
1 picosecond = gumi
-12 chepiri
1 femtosecond = gumi
-15 chepiri
Naizvozvo, musiyano mukuru pakati penanosecond laser, picosecond laser uye femtosecond laser uri munguva yavo yenguva.
Zvinoreva utlrafast laserKare kare, vanhu vakaedza kushandisa laser kuita micromachining. Nekudaro, sezvo iyo yechinyakare laser ine refu pulse hupamhi uye yakaderera laser kusimba, zvinhu zvinogadziriswa zviri nyore kunyunguduka uye kuramba zvichibuda. Kunyangwe Laser beam inogona kutariswa mune diki diki laser nzvimbo, kupisa kupisa kune izvo zvinhu kuchiri kwakakura, izvo zvinomisa iko kurongeka kwekugadzirisa. Kungoderedza kupisa kwemhepo kunogona kuvandudza hutano hwekugadzirisa.
Asi kana ultrafast laser iri kushanda pazvinhu, iyo yekugadzirisa maitiro ine shanduko huru. Sezvo simba rekupuruzira rinowedzera zvakanyanya, iyo yakanyanya simba density ine simba rakakwana rekudzima magetsi ekunze. Sezvo kupindirana pakati peiyo Ultrafast laser uye zvigadzirwa kuri kupfupika, iyo ion yakatove yakabviswa pamusoro pezvinhu isati yaendesa simba kune zvakatenderedza zvinhu, saka hapana kupisa kunozounzwa kune zvakatenderedza zvinhu. Naizvozvo, ultrafast laser processing inozivikanwawo sekutonhora kugadzirisa.
Kune akasiyana akasiyana ekushandisa e Ultrafast laser mukugadzirwa kwemaindasitiri. Pazasi isu tichadoma mashoma:
1.Hole kucheraMune redunhu bhodhi dhizaini, vanhu vanotanga kushandisa Ceramics hwaro kutsiva yechinyakare epurasitiki hwaro kuti vaone zviri nani kupisa conductivity. Kuti ubatanidze zvikamu zvemagetsi, zviuru zve μm level maburi madiki anoda kudhirwa pabhodhi. Naizvozvo, kuchengetedza hwaro hwakasimba pasina kukanganiswa nekupisa kwekupinza panguva yekuchera gomba kwave kwakakosha. Uye picosecond lase ndiyo yakanakira chishandiso.
Picosecond laser inoona kuchera gomba nekubhowekana kunofinha uye inochengeta kufanana kwegomba. Kuwedzera kune redunhu bhodhi, picosecond laser inoshandawo kuita yemhando yepamusoro kuchera gomba papurasitiki yakaonda firimu, semiconductor, simbi firimu uye safiro.
2.Kunyora nekuchekaMutsetse unogona kuumbwa nekuenderera mberi kutarisisa kuvhara iyo laser pulse. Izvi zvinoda huwandu hukuru hwekuvheneka kuitira kuti upinde mukati mukati memakeramiki kusvika mutsetse wasvika 1/6 yehukobvu hwezvinhu. Wobva wapatsanura yega yega module kubva kune ceramics hwaro pamwe nemitsara iyi. Kupatsanura uku kunonzi kunyora.
Imwe nzira yekuparadzanisa ndeye pulse laser ablation yekucheka. Zvinoda kubvisa zvinhu kusvikira zvinhu zvanyatsochekwa.
Kune iyo iri pamusoro kunyora nekucheka, picosecond laser uye nanosecond laser ndiyo yakanakira sarudzo.
3.Kubvisa kubvisaImwe micromachining application yeultrafast laser ndeyekubvisa coating. Izvi zvinoreva kunyatsobvisa coating pasina kukuvadza kana kukuvadza zvishoma zvigadzirwa zvenheyo. Iyo ablation inogona kuve mitsetse yemamicrometer akati wandei yakafara kana yakakura chiyero che akati wandei sikweya masendimita. Sezvo hupamhi hwekuputira hwakanyanya kuduku kudarika hupamhi hwekubvisa, kupisa hakuzoende kune rumwe rutivi. Izvi zvinoita kuti nanosecond laser ive yakakodzera.
Ultrafast laser ine yakakura kugona uye inovimbisa ramangwana. Iyo inoratidzira hapana post-processing inodiwa, nyore kusanganisa, yakakwirira kugadzirisa kushanda zvakanaka, kuderera kwekushandisa kwezvinhu, kuderera kwemamiriro ekunze. Yakave yakashandiswa zvakanyanya mumotokari, zvemagetsi, mudziyo, kugadzira michina, nezvimwe .. Kuchengeta ultrafast laser ichimhanya chaizvo mukufamba kwenguva, tembiricha yayo inofanirwa kuchengetedzwa zvakanaka. S&A Teyu CWUP seriesportable water chillers akanyanya kunaka kutonhora ekupedzisira ekupedzisira lasers anosvika 30W. Aya maLaser chiller mayunitsi anoratidza yakanyanya kukwirisa mwero weiyo ± 0.1 ℃ uye inotsigira Modbus 485 kutaurirana basa. Iine pombi yakagadzirwa nemazvo, mukana wekugadzira bubble wave mudiki kwazvo, izvo zvinodzikisira maitiro kune Ultrafast laser.
