Ikamva loomatshini bokuchwetheza ngokuchanekileyo ngokukhawuleza

Umatshini wokulungisa ngokuchanekileyo yinxalenye ebalulekileyo yokwenziwa kwelaser. Uphuhliswe ukusuka kwi-nanosecond green/ultraviolet lasers zakuqala ukuya kwi-picosecond kunye ne-femtosecond lasers, kwaye ngoku ii-ultrafast lasers zezona ziphambili. Iza kuba yintoni indlela yophuhliso lwexesha elizayo lomatshini wokulungisa ngokuchanekileyo we-ultrafast?

Iilaser ezikhawulezayo zazizezokuqala ukulandela indlela yetekhnoloji yelaser eqinileyo. Iilaser eziqinileyo zineempawu zamandla aphezulu okukhupha, uzinzo oluphezulu kunye nolawulo oluhle. Ziyindlela yokuphucula i-nanosecond/sub-nanosecond solid-state lasers, ngoko ke iilaser ze-picosecond femtosecond solid-state zithatha indawo ye-nanoseconds. Iilaser ze-solid-state zinengqondo. Iilaser zefayibha zithandwa, iilaser ezikhawulezayo nazo ziye zaya kwicala le-fiber lasers, kwaye iilaser zefayibha ze-picosecond/femtosecond ziye zavela ngokukhawuleza, zikhuphisana neelaser eziqinileyo ezikhawulezayo.

Uphawu olubalulekileyo lwee-laser ezikhawulezayo kukuphuculwa ukusuka kwi-infrared ukuya kwi-ultraviolet. Ukucubungula i-infrared picosecond laser kunefuthe eligqibeleleyo ekusikeni nasekubholeni iglasi, ii-ceramic substrates, ukusika i-wafer, njl. Nangona kunjalo, ukukhanya kwe-ultraviolet phantsi kwentsikelelo yee-pulses ezimfutshane kakhulu kunokufezekisa "ukucubungula okubandayo" kakhulu, kwaye ukubhoboza nokusika kwizinto azinazo iimpawu zokutsha, nto leyo efezekisa ukucubungula okugqibeleleyo.

Indlela yokwandisa ubuchwepheshe be-ultra-short pulse laser kukwandisa amandla , ukusuka kwi-3 watts kunye ne-5 watts kwiintsuku zokuqala ukuya kwinqanaba langoku le-100 watts. Okwangoku, ukucubungula ngokuchanekileyo kwimarike kudla ngokusebenzisa amandla angama-20 watts ukuya kuma-50 watts. Kwaye iziko laseJamani liqalile ukujongana nengxaki ye-ultrafast lasers yenqanaba le-kilowatt. I-S&A i-laser chiller ekhawulezayo kakhulu Olu luhlu lunokuhlangabezana neemfuno zokupholisa ze-laser ezininzi ezikhawulezayo kwimarike, kwaye luphucule umgca wemveliso ye-S&A chiller ngokweenguqu zemarike.

Ichatshazelwe zizinto ezifana ne-COVID-19 kunye nemeko-bume yezoqoqosho engaqinisekanga, imfuno yezinto ze-elektroniki zabathengi ezifana neewotshi kunye neetablet ziya kucotha ngo-2022, kwaye imfuno ye-ultrafast lasers kwi-PCB (ibhodi yesekethe eprintiweyo), iiphaneli zokubonisa kunye ne-LED ziya kuncipha. Kuphela ziintsimi zesangqa kunye neetship eziqhutywayo, kwaye i-ultrafast laser precision machining ihlangabezane nemingeni yokukhula.

Indlela yokuphuma kwiilaser ezikhawulezayo kukwandisa amandla nokuphuhlisa iimeko zokusetyenziswa ngakumbi. Iipicoseconds ezilikhulu-watt ziya kuba yinto eqhelekileyo kwixesha elizayo. Izinga eliphezulu lokuphindaphinda kunye neelaser zamandla aphezulu okubetha zivumela amandla amakhulu okucubungula, njengokusika nokubhoboza iglasi ukuya kuthi ga kwi-8 mm ubukhulu. Ilaser ye-picosecond ye-UV ayinaxinzelelo lobushushu kwaye ifanelekile ukucubungula izinto ezinobuthathaka kakhulu, ezifana nee-stent zokusika kunye nezinye iimveliso zonyango ezinobuthathaka kakhulu.

Kwimveliso ye-elektroniki edityanisiweyo neyokwenziwa, kwi-aerospace, kwi-biomedical, kwi-semiconductor wafer nakwamanye amashishini, kuya kubakho inani elikhulu leemfuno zoomatshini bokuchaneka kwiindawo ezithile, kwaye ukucubungula i-laser engadibaniyo kuya kuba lolona khetho lufanelekileyo. Xa imeko yezoqoqosho iphucuka, ukusetyenziswa kwe-laser ekhawulezayo ngokuqinisekileyo kuya kubuyela kwindlela yokukhula okuphezulu.
