Ikamva lobuchwephesha obuchaneke kakhulu

Ukuchaneka komatshini yinxalenye ebalulekileyo yokwenziwa kwelaser. Iphuhliswe ukusuka ekuqaleni kwe-nanosecond eluhlaza / i-ultraviolet lasers ukuya kwi-picosecond kunye ne-laser ye-femtosecond, kwaye ngoku ii-lases ze-ultrafast zezona ziphambili. Iyakuba yintoni intsingiselo yophuhliso lwexesha elizayo lomatshini ochaneke kakhulu?

Iilaser ezikhawulezayo zaba zezokuqala ukulandela indlela yobuchwepheshe belaser yelizwe eliqinileyo. I-Laser-state eqinile ineempawu zamandla aphezulu, uzinzo oluphezulu kunye nokulawula okulungileyo. Zikuqhubekeka kophuculo lwe-nanosecond/sub-nanosecond eqinileyo-state lasers, ngoko ke i-picosecond femtosecond i-solid-state lasers ithatha indawo ye-nanoseconds eyomeleleyo yemo yelasesi iyavakala. I-Fiber lasers iyathandwa, iilaser ze-ultrafast nazo ziye zaya kwicala le-fiber lasers, kunye ne-picosecond/femtosecond fiber lasers ziye zavela ngokukhawuleza, zikhuphisana nee-laser eziqinileyo ze-ultrafast.

Inqaku elibalulekileyo lelaser ezikhawulezayo kukuphucula ukusuka kwi-infrared ukuya kwi-ultraviolet. I-infrared picosecond laser processing inempembelelo ephantse igqibelele kwiglasi yokusika kunye nokugrumba, i-ceramic substrates, i-wafer cutting, njl. Nangona kunjalo, ukukhanya kwe-ultraviolet phantsi kwentsikelelo ye-ultra-short pulses kunokufikelela "ukucutshungulwa okubandayo" ngokugqithiseleyo, kwaye ukubetha kunye nokusika kwizinto eziphathekayo phantse akukho manqaku okutshisa, ukuphumeza ukusetyenzwa okugqibeleleyo.

Ukwandiswa kwetekhnoloji ye-laser ye-ultra-short pulse kukwandisa amandla , ukusuka kwi-3 watts kunye ne-5 watts ngeentsuku zokuqala ukuya kwinqanaba langoku le-100 watts. Okwangoku, ukusetyenzwa ngokuchanekileyo kwimarike ngokuqhelekileyo kusebenzisa iiwatts ezingama-20 ukuya kuma-50 amandla. Kwaye iziko laseJamani liqalile ukujongana nengxaki ye-kilowatt-level ultrafast lasers. S&A ultrafast laser chiller series angahlangabezana neemfuno zokupholisa uninzi lasers ultrafast kwimarike, kwaye etyebisa S&A umgca imveliso chiller ngokotshintsho kwimarike.

Ukuchatshazelwa zizinto ezinje nge-COVID-19 kunye nokungaqinisekanga kokusingqongileyo kwezoqoqosho, imfuno yezinto zombane zabathengi ezinje ngeewotshi kunye neetafile ziya kuncipha ngo-2022, kunye nemfuno yee-laser ezikhawulezayo kwi-PCB (ibhodi yesekethe eprintiweyo), iiphaneli zokubonisa kunye ne-LED ziya kuncipha. Kuphela imimandla yesangqa kunye ne-chip eqhutywe, kwaye i-ultrafast laser precision machining iye yadibana nemingeni yokukhula.

Indlela yokuphuma kwii-lasers ze-ultrafast kukwandisa amandla kunye nokuphuhlisa iimeko ezininzi zesicelo. Ikhulu leewatt picoseconds ziya kuba semgangathweni kwixesha elizayo. Isantya esiphezulu sokuphindaphinda kunye ne-laser yamandla e-pulse ephezulu yenza ukubanakho ukusetyenzwa okukhulu ngakumbi, njengokusika kunye nokugrumba iglasi ukuya kuthi ga kwi-8 mm ubukhulu. I-laser ye-picosecond ye-UV iphantse ingabinaxinzelelo lobushushu kwaye ilungele ukusetyenzwa kwezixhobo ezibuthathaka kakhulu, ezinje ngee-stents zokusika kunye nezinye iimveliso zonyango ezinovakalelo kakhulu.

Kwindibano yemveliso ye-elektroniki kunye nokuveliswa, i-aerospace, i-biomedical, i-wafer ye-semiconductor kunye namanye amashishini, kuya kubakho inani elikhulu leemfuno ze-machining ezichanekileyo zamacandelo, kwaye ukusetyenzwa kwe-laser engaqhagamshelani kuya kuba lolona khetho lungcono. Xa imeko yezoqoqosho ithatha, ukusetyenziswa kwe-laser ultrafast ngokuqinisekileyo kuya kubuyela kumkhondo wokukhula okuphezulu.
