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. Kukuqhubekeka kophuculo lwe-nanosecond/sub-nanosecond esomeleleyo-state lasers, ke ngoko i-picosecond femtosecond i-solid-state lasers ithatha indawo ye-nanosecond-slid-state lasers 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. Ukusetyenzwa kwe-laser ye-infrared picosecond kunempembelelo ephantse igqibelele ekusikeni kweglasi kunye nokugrumba, i-ceramic substrates, ukusika i-wafer, njl. Nangona kunjalo, ukukhanya kwe-ultraviolet phantsi kweentsikelelo ze-ultra-short pulses kunokufikelela "ukulungiswa okubandayo" ngokugqithiseleyo, kwaye ukubethelwa kunye nokusika kwizinto eziphathekayo akukho manqaku okutshisa, ukufezekisa ukuqhutyelwa ngokugqibeleleyo.

Indlela yokwandisa itekhnoloji ye-ultra-short pulse laser kukwandisa amandla , ukusuka kwi-3 watts kunye ne-5 watts kwiintsuku zokuqala ukuya kwinqanaba langoku le-100 watt. Okwangoku, ukusetyenzwa ngokuchanekileyo kwimarike ngokuqhelekileyo kusebenzisa iiwatts ezingama-20 ukuya kuma-50 wamandla. Kwaye iziko laseJamani liqalise ukujongana nengxaki ye-kilowatt-level ultrafast lasers. S&I-laser chiller ye-ultrafast Uthotho lunokuhlangabezana neemfuno zokupholisa uninzi lweelaser ezikhawulezayo kwintengiso, kwaye zityebise i-S&A umgca imveliso chiller ngokweenguqu 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 zokusetyenziswa. 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.
