Ikusasa le-ultrafast precision machining

Ukunemba kwemishini kuyingxenye ebalulekile yokukhiqiza i-laser. Ithuthukiswe kusukela kumalaser aqinile e-nanosecond aluhlaza/e-ultraviolet kuya kuma-laser e-picosecond kanye ne-femtosecond, futhi manje ama-laser asheshayo aseyiwona ahamba phambili. Izoba yini inkambiso yentuthuko yesikhathi esizayo yomshini wokunemba we-ultrafast?

Ama-laser asheshayo abe ngawokuqala ukulandela umzila wobuchwepheshe be-laser wesifunda esiqinile. Ama-laser ezwe eliqinile anezici zamandla aphezulu aphumayo, ukuzinza okuphezulu nokulawula okuhle. Ziwukuqhutshekiselwa phambili kokuthuthukiswa kwe-nanosecond/sub-nanosecond solid-state lasers, ngakho-ke ama-lasecond femtosecond solid-state lasers athatha indawo yama-nanoseconds solid-state lasers anengqondo. Ama-laser e-fiber adumile, ama-laser asheshayo nawo asuke ebheke lapho kuqondiswa khona ama-laser, futhi ama-laser e-picosecond/femtosecond fiber avele ngokushesha, aqhudelana namalaser aqinile aqinile.

Isici esibalulekile sama-lasers asheshayo ukuthuthukiswa kwe-infrared kuya ku-ultraviolet. Ukucutshungulwa kwe-laser ye-picosecond ye-infrared kunomphumela ocishe uphelele ekusikeni ingilazi nokubhoboza, ama-substrates e-ceramic, ukusika i-wafer, njll. Kodwa-ke, ukukhanya kwe-ultraviolet ngaphansi kwesibusiso se-ultra-short pulses kungafinyelela "ukucubungula okubandayo" kuze kube ngokwedlulele, futhi ukubhoboza nokusika izinto ezibonakalayo cishe akukho zimpawu zokushisa, ukufeza ukucubungula okuphelele.

Umkhuba wokunwetshwa kwezobuchwepheshe we-ultra-short pulse laser ukukhulisa amandla , kusukela ku-3 watts kanye nama-watts angu-5 ezinsukwini zakuqala ukuya ezingeni lamanje lama-watt angu-100. Njengamanje, ukucutshungulwa okunembayo emakethe ngokuvamile kusebenzisa ama-watts angama-20 kuye kwangama-50 wamandla. Futhi isikhungo saseJalimane sesiqalile ukubhekana nenkinga yama-lasers we-kilowatt-level ultrafast. S&I-laser chiller esheshayo uchungechunge lungahlangabezana nezidingo zokupholisa zamalaser amaningi asheshayo emakethe, futhi lunothise i-S&Umugqa womkhiqizo opholile ngokuya ngezinguquko zemakethe.

Ithintwa izinto ezifana ne-COVID-19 kanye nesimo somnotho esingaqinisekile, isidingo sezinto zikagesi ezithengwayo ezifana namawashi namathebulethi sizokwehla ngo-2022, kanye nesidingo samalaser asheshayo ku-PCB (ibhodi lesifunda eliphrintiwe), amaphaneli wokubonisa kanye ne-LED kuzokwehla. Izinkambu zendilinga nezicucu kuphela ezishayeliwe, futhi ukwenziwa kwemishini kwe-laser esheshayo kuhlangabezane nezinselelo zokukhula.

Indlela yokuphuma kuma-laser asheshayo ukukhulisa amandla nokuthuthukisa izimo zohlelo lokusebenza. Ama-piccosecond-watt ayikhulu azoba ajwayelekile ngokuzayo. Izinga eliphezulu lokuphindaphinda kanye nama-laser wamandla we-pulse energy anika amandla amakhulu okucubungula, njengokusika nokubhoboza ingilazi kuze kufike ku-8 mm ubukhulu. I-UV picosecond laser cishe ayinakho ukucindezeleka okushisayo futhi ilungele ukucubungula izinto ezibucayi kakhulu, njengama-stents okusika neminye imikhiqizo yezokwelapha ebucayi kakhulu.

Ekuhlanganiseni nasekukhiqizeni umkhiqizo we-elekthronikhi, i-aerospace, i-biomedical, i-semiconductor wafer nezinye izimboni, kuzoba nenani elikhulu lezidingo zokunemba zemishini yezingxenye, futhi ukucutshungulwa kwe-laser okungaxhunywanga kuzoba yisinqumo esingcono kakhulu. Lapho isimo somnotho sithuthuka, ukusetshenziswa kwama-laser asheshayo kuzobuyela emzileni wokukhula okuphezulu.
