Unogona here kuona musiyano uripo pakati pe nanosecond laser, picosecond laser uye femtosecond laser?

Kutanga, ngationei kuti aya mashoko ekuti "echipiri" anorevei.

1 nanosekondi = 10^-9 chepiri

1 picosecond = 10^-12 chepiri

1 femtosekondi = 10^-15 chepiri

Saka, musiyano mukuru pakati pe nanosecond laser, picosecond laser uye femtosecond laser uri muhurefu hwenguva yadzo.

Zvinoreva utlrafast laser

Kare kare, vanhu vaiedza kushandisa laser kuita micromachining. Zvisinei, sezvo laser yechinyakare ine upamhi hwakareba hwepulse uye simba rakaderera re laser, zvinhu zvinogadziriswa zviri nyore kunyunguduka uye kuramba zvichibuda. Kunyangwe danda re laser richigona kunangidzirwa panzvimbo diki ye laser, kupisa kwezvinhu kuchiri kukuru, izvo zvinoderedza kunyatsogadzirwa. Kuderedza kupisa chete ndiko kunogona kuvandudza kunaka kwekugadzirwa.

Asi kana laser inokurumidza kushanda pazvinhu, mhedzisiro yekugadzirisa inochinja zvakanyanya. Sezvo simba rekurova kwemoyo richikwira zvakanyanya, simba rakawanda rine simba rakakwana rekubvisa magetsi ekunze. Sezvo kudyidzana pakati pe laser inokurumidza nezvinhu kuri kupfupi, iyo ion yatove yakabviswa pamusoro pezvinhu isati yaendesa simba kuzvinhu zvakatenderedza, saka hapana mhedzisiro yekupisa ichaunzwa kuzvinhu zvakatenderedza. Naizvozvo, ultrafast laser processing inozivikanwawo se cold processing.

Kune mhando dzakasiyana dzekushandiswa kwe ultrafast laser mukugadzirwa kwemaindasitiri. Pazasi tichataura mashoma:

1. Kuboora maburi

Mukugadzira mabhodhi edunhu, vanhu vanotanga kushandisa ceramics foundation kutsiva foundation yepurasitiki yechinyakare kuti vagadzire kupisa kuri nani. Kuti vabatanidze zvikamu zvemagetsi, maburi madiki ane zviuru zve μm level anofanira kuboorwa pabhodhi. Saka, kuchengetedza foundation yakagadzikana pasina kukanganiswa nekupisa panguva yekuboorwa kwemaburi kwave kwakakosha zvikuru. Uye picosecond laser ndiyo chishandiso chakakodzera.

Picosecond laser inoita kuti gomba riboore nekuridza ngoma rirambe richibooresa uye inoita kuti gomba rirambe rakafanana. Pamusoro pebhodhi redunhu, picosecond laser inoshandawo pakuita gomba remhando yepamusoro papurasitiki yakatetepa, semiconductor, firimu resimbi nesafire.

2. Kunyora nekucheka

Tambo inogona kugadzirwa nekuskena nguva dzose kuti ivhare kurira kwelaser. Izvi zvinoda kuskena kwakawanda kuitira kuti ipinde mukati meceramics kusvika mutsetse wasvika 1/6 yeukobvu hwezvinhu. Wobva waparadzanisa module yega yega kubva panheyo yeceramics pamwe chete nemitsetse iyi. Rudzi urwu rwekuparadzanisa runonzi scribing.

Imwe nzira yekuparadzanisa ndeyekucheka ne laser ablation. Zvinoda kubvisa chinhu kusvika chinhu chachekwa chose.

Pakunyora nekucheka zviri pamusoro apa, picosecond laser ne nanosecond laser ndiyo sarudzo dzakanakira.

3. Kubviswa kwependi

Imwe nzira yekubvisa coating ne laser inokurumidza (micromachine) ndeyekubvisa coating. Izvi zvinoreva kubvisa coating nemazvo pasina kukuvadza kana kukuvadza zvishoma zvinhu zvehwaro. Coating inogona kuva mitsetse ine upamhi hwema micrometer akawanda kana saizi yakakura yemasendimita akati wandei. Sezvo upamhi hwecoating huri hudiki pane upamhi hwecoating, kupisa hakuzopfuuriri kudivi. Izvi zvinoita kuti nanosecond laser ive yakakodzera.

Laser yeUltrafast ine mukana mukuru uye remangwana rakanaka. Haina basa rekugadzirisa mushure mekushandisa, iri nyore kubatanidza, inoshanda zvakanyanya pakugadzira, haishandisi zvinhu zvakawanda, haina kusvibiswa kwakawanda. Yave ichishandiswa zvakanyanya mumotokari, zvemagetsi, zvemidziyo, zvemichina, nezvimwewo. Kuti laser yeUltrafast irambe ichishanda zvakanaka kwenguva refu, tembiricha yayo inofanira kuchengetedzwa zvakanaka. MaS&A Teyu CWUP series emvura anotonhorera akanakira kutonhodza maLaser eUltrafast anosvika 30W. Aya maLaser chiller ane mwero wakanyanya wekunyatsojeka we ±0.1℃ uye anotsigira basa rekutaurirana reModbus 485. Nepombi yakagadzirwa zvakanaka, mukana wekugadzira mabubble wava mudiki, izvo zvinoderedza simba reLaser yeUltrafast.
