Yav tom ntej ntawm kev ua haujlwm precision ultrafast

Kev ua kom raug yog ib feem tseem ceeb ntawm kev tsim khoom laser. Nws tau tsim los ntawm cov khoom siv nanosecond ntsuab / ultraviolet thaum ntxov mus rau picosecond thiab femtosecond lasers, thiab tam sim no ultrafast lasers yog cov khoom siv tseem ceeb. Yuav ua li cas rau yav tom ntej kev txhim kho ntawm ultrafast precision machining?

Cov lasers ultrafast yog thawj cov uas ua raws li txoj kev siv tshuab laser solid-state. Cov lasers solid-state muaj cov yam ntxwv ntawm lub zog tso zis siab, kev ruaj khov siab thiab kev tswj hwm zoo. Lawv yog qhov txuas ntxiv ntawm nanosecond / sub-nanosecond solid-state lasers, yog li picosecond femtosecond solid-state lasers hloov nanoseconds solid-state lasers yog qhov muaj tseeb. Fiber lasers nrov, ultrafast lasers kuj tau tsiv mus rau qhov kev taw qhia ntawm fiber lasers, thiab picosecond / femtosecond fiber lasers tau tshwm sim sai, sib tw nrog cov lasers ultrafast solid.

Ib qho tseem ceeb ntawm cov lasers ultrafast yog qhov hloov kho dua tshiab ntawm infrared mus rau ultraviolet. Infrared picosecond laser processing muaj qhov cuam tshuam zoo kawg nkaus hauv kev txiav iav thiab drilling, ceramic substrates, wafer txiav, thiab lwm yam. Txawm li cas los xij, lub teeb ultraviolet nyob rau hauv qhov koob hmoov ntawm ultra-luv pulses tuaj yeem ua tiav "txias ua tiav" mus rau qhov kawg, thiab qhov xuas nrig thiab txiav ntawm cov khoom yuav luag tsis muaj cov cim kub hnyiab, ua tiav kev ua tiav zoo meej.

Qhov kev nthuav dav ntawm thev naus laus zis ntawm ultra-luv pulse laser yog kom nce lub zog , los ntawm 3 watts thiab 5 watts thaum ntxov mus rau qib 100 watt tam sim no. Tam sim no, kev ua tiav precision hauv kev ua lag luam feem ntau siv 20 watts txog 50 watts ntawm lub zog. Thiab ib lub koom haum German tau pib daws qhov teeb meem ntawm kilowatt-level ultrafast lasers. S&A lub tshuab cua txias laser ceev ceev cov koob tuaj yeem ua tau raws li qhov xav tau txias ntawm feem ntau ultrafast lasers hauv kev ua lag luam, thiab nplua nuj S&A chiller cov khoom kab raws li kev hloov pauv ntawm kev ua lag luam.

Cuam tshuam los ntawm cov yam xws li COVID-19 thiab qhov chaw tsis paub meej txog kev lag luam, qhov kev thov rau cov khoom siv hluav taws xob xws li cov moos thiab cov ntsiav tshuaj yuav qeeb hauv xyoo 2022, thiab qhov kev thov rau ultrafast lasers hauv PCB (printed circuit board), cov vaj huam sib luag zaub thiab LED yuav poob qis. Tsuas yog lub voj voog thiab cov teb nti tau tsav, thiab ultrafast laser precision machining tau ntsib cov teeb meem kev loj hlob.

Txoj kev tawm rau cov lasers ultrafast yog kom nce lub zog thiab tsim ntau qhov xwm txheej ntawm daim ntawv thov. Puas-watt picoseconds yuav dhau los ua tus qauv yav tom ntej. Cov nqi rov ua dua siab thiab cov lasers zog siab ua rau muaj peev xwm ua tiav ntau dua, xws li txiav thiab tho iav txog li 8 hli tuab. Lub UV picosecond laser yuav luag tsis muaj kev ntxhov siab thermal thiab tsim nyog rau kev ua cov ntaub ntawv rhiab heev, xws li txiav stents thiab lwm yam khoom kho mob rhiab heev.

Hauv kev sib dhos thiab tsim cov khoom siv hluav taws xob, aerospace, biomedical, semiconductor wafer thiab lwm yam kev lag luam, yuav muaj ntau qhov kev xav tau precision machining rau cov khoom, thiab kev ua laser tsis sib cuag yuav yog qhov kev xaiv zoo tshaj plaws. Thaum lub sijhawm kev lag luam zoo dua, kev siv ultrafast lasers yuav rov qab mus rau txoj kev loj hlob siab.
