Tsogolo la ultrafast mwatsatanetsatane Machining

Machining mwatsatanetsatane ndi gawo lofunikira pakupanga laser. Yapangidwa kuchokera ku ma lasers olimba a nanosecond obiriwira / a ultraviolet kupita ku ma lasers a picosecond ndi femtosecond, ndipo tsopano ma lasers othamanga kwambiri ndi omwe amapezeka kwambiri. Kodi chitukuko chamtsogolo cha makina a ultrafast precision chidzakhala chiyani?

Ma lasers a Ultrafast anali oyamba kutsatira njira yolimba yaukadaulo ya laser. Ma lasers olimba ali ndi mawonekedwe amphamvu yotulutsa, kukhazikika kwakukulu komanso kuwongolera bwino. Ndiwo kupititsa patsogolo kwa nanosecond/sub-nanosecond solid-state lasers, kotero ma lasers a picosecond femtosecond solid-state m'malo mwa nanoseconds solid-state lasers ndi zomveka. Ma fiber lasers ndi otchuka, ma lasers a ultrafast nawonso asunthira komwe kuli ma lasers, ndipo ma picosecond/femtosecond fiber lasers atuluka mwachangu, kupikisana ndi ma laser olimba kwambiri.

Chinthu chofunika kwambiri cha lasers ultrafast ndikukweza kuchokera ku infrared kupita ku ultraviolet. Infrared picosecond laser processing imakhala ndi zotsatira zabwino kwambiri pakudula magalasi ndi kubowola, ma ceramic substrates, wafer kudula, etc. Komabe, kuwala kwa ultraviolet pansi pa dalitso la ultra-short pulses kumatha kukwaniritsa "kuzizira kozizira" mopitirira muyeso, ndipo kukhomerera ndi kudula pazinthuzo kulibe zizindikiro zowotcha, kukwaniritsa processing wangwiro.

Kukula kwaukadaulo kwa ultra-short pulse laser ndikuwonjezera mphamvu , kuchokera ku 3 watts ndi 5 watts m'masiku oyambirira kufika pa mlingo wamakono wa 100 watts. Pakalipano, kukonza molondola pamsika nthawi zambiri kumagwiritsa ntchito ma watts 20 mpaka mawati 50 amphamvu. Ndipo bungwe la Germany layamba kuthana ndi vuto la ma kilowatt-level ultrafast lasers. S&Wozizira kwambiri wa laser mndandanda amatha kukwaniritsa zosowa zoziziritsa za ma lasers othamanga kwambiri pamsika, ndikulemeretsa S&A chiller mankhwala mzere malinga ndi kusintha msika.

Kukhudzidwa ndi zinthu monga COVID-19 komanso kusakhazikika kwachuma, kufunikira kwamagetsi ogula monga mawotchi ndi mapiritsi kudzakhala kwaulesi mu 2022, ndipo kufunikira kwa ma lasers othamanga kwambiri mu PCB (board board yosindikizidwa), mapanelo owonetsera ndi ma LED atsika. Malo ozungulira okha ndi chip ndiomwe adayendetsedwa, ndipo makina olondola kwambiri a laser akumana ndi zovuta zakukula.

Njira yotulukira ma lasers othamanga kwambiri ndikuwonjezera mphamvu ndikupanga zochitika zambiri zogwiritsira ntchito. Ma picoseconds mazanamazana adzakhala okhazikika mtsogolomo. Kuchulukitsa kubwereza komanso ma lasers amphamvu amphamvu amathandizira kuti pakhale kuthekera kokulirapo, monga kudula ndi kubowola magalasi mpaka 8 mm wandiweyani. Laser ya UV picosecond ilibe kupsinjika kwamatenthedwe ndipo ndiyoyenera kukonza zida zovutirapo, monga kudula ma stents ndi zinthu zina zachipatala zomwe zimakhala zovuta kwambiri.

Pamsonkhano wazinthu zamagetsi ndi kupanga, zakuthambo, zamoyo, zowotchera semiconductor ndi mafakitale ena, padzakhala kuchuluka kwazinthu zofunikira pakukonza magawo, ndipo kusalumikizana kwa laser kudzakhala chisankho chabwino kwambiri. Chikhalidwe chazachuma chikayamba, kugwiritsa ntchito ma lasers a ultrafast kudzabwereranso pakukula kwakukulu.
