Lub neej yav tom ntej ntawm ultrafast precision machining

Precision machining yog ib feem tseem ceeb ntawm laser manufacturing. Nws tau tsim los ntawm cov khoom thaum ntxov nanosecond ntsuab / ultraviolet lasers rau picosecond thiab femtosecond lasers, thiab tam sim no ultrafast lasers yog lub ntsiab. Dab tsi yuav yog qhov kev txhim kho yav tom ntej ntawm ultrafast precision machining?

Ultrafast lasers yog thawj zaug ua raws li cov khoom siv hauv lub xeev laser txoj kev. Solid-state lasers muaj cov yam ntxwv ntawm lub zog tso zis siab, ruaj khov thiab tswj tau zoo. Lawv yog cov hloov kho txuas ntxiv ntawm nanosecond / sub-nanosecond solid-state lasers, yog li picosecond femtosecond solid-state lasers hloov nanoseconds solid-state lasers yog cov laj thawj. Fiber lasers yog nrov, ultrafast lasers kuj tau tsiv mus rau cov kev taw qhia ntawm fiber ntau lasers, thiab picosecond / femtosecond fiber lasers tau tshwm sim sai heev, sib tw nrog cov khoom ultrafast lasers.

Ib qho tseem ceeb feature ntawm ultrafast lasers yog lub upgrade ntawm infrared mus rau ultraviolet. Infrared picosecond laser ua tau zoo yuav luag zoo meej hauv iav txiav thiab drilling, ceramic substrates, wafer txiav, thiab lwm yam. Txawm li cas los xij, lub teeb ci ultraviolet nyob rau hauv qhov koob hmoov ntawm ultra-luv pulses tuaj yeem ua tiav "kev ua haujlwm txias" mus rau qhov kawg, thiab kev xuas nrig ntaus thiab txiav ntawm cov khoom yuav luag tsis muaj cov cim scorch, ua tiav kev ua tiav.

Cov txheej txheem nthuav dav ntawm ultra-luv mem tes laser yog ua kom lub zog , los ntawm 3 watts thiab 5 watts nyob rau hauv thaum ntxov hnub mus rau 100 watt theem tam sim no. Tam sim no, kev ua tiav hauv kev ua lag luam feem ntau siv 20 watts rau 50 watts ntawm lub zog. Thiab ib lub tuam txhab German tau pib daws qhov teeb meem ntawm kilowatt-theem ultrafast lasers. S&Ultrafast laser chiller series tuaj yeem ua tau raws li qhov xav tau txias ntawm cov lasers ultrafast hauv kev ua lag luam, thiab txhawb nqa S&Lub chiller khoom kab raws li kev lag luam hloov pauv.

Kev cuam tshuam los ntawm cov xwm txheej xws li COVID-19 thiab qhov chaw tsis paub txog kev lag luam, qhov kev thov rau cov neeg siv khoom siv hluav taws xob xws li watches thiab ntsiav tshuaj yuav qeeb hauv xyoo 2022, thiab qhov kev thov rau ultrafast lasers hauv PCB (luam tawm Circuit Board), cov khoom vaj huam sib luag thiab LED yuav poob qis. Tsuas yog lub voj voog thiab nti teb tau raug tsav, thiab ultrafast laser precision machining tau ntsib txoj kev loj hlob.

Txoj kev tawm rau ultrafast lasers yog kom muaj zog thiab tsim ntau daim ntawv thov scenarios. Ntau pua watt picoseconds yuav dhau los ua tus qauv yav tom ntej. High repetition rate thiab siab pulse zog lasers pab kom muaj peev xwm ua tau ntau dua, xws li txiav thiab drilling iav txog li 8 hli tuab. UV picosecond laser yuav luag tsis muaj thermal stress thiab tsim nyog rau kev ua cov ntaub ntawv rhiab heev, xws li txiav stents thiab lwm yam khoom siv kho mob rhiab heev.

Nyob rau hauv cov khoom siv hluav taws xob sib dhos thiab kev tsim khoom, aerospace, biomedical, semiconductor wafer thiab lwm yam lag luam, yuav muaj ntau qhov kev txiav txim siab zoo rau cov khoom, thiab kev ua haujlwm tsis sib cuag laser yuav yog qhov kev xaiv zoo tshaj plaws. Thaum kev lag luam ib puag ncig tuaj tos, daim ntawv thov ntawm ultrafast lasers yuav inevitably rov qab mus rau txoj kev loj hlob siab.
