Dab tsi yog ultrafast laser ua? Ultrafast laser yog ib tug mem tes laser nrog mem tes dav ntawm picosecond qib thiab hauv qab no. 1 picosecond yog sib npaug rau 10⁻¹² ntawm ib lub thib ob, qhov ceev ntawm lub teeb nyob rau hauv huab cua yog 3 X 10⁸m / s, thiab nws yuav siv li 1.3 vib nas this rau lub teeb los ntawm lub ntiaj teb mus rau lub hli. Thaum lub sijhawm 1-picosecond, qhov kev ncua deb ntawm lub teeb yog 0.3 hli. Lub pulse laser yog tawm hauv lub sijhawm luv luv uas lub sijhawm sib cuam tshuam ntawm ultrafast laser thiab cov ntaub ntawv tseem luv. Piv nrog rau cov txheej txheem laser, cov nyhuv tshav kub ntawm ultrafast laser ua yog me me, yog li ultrafast laser ua yog tsuas yog siv nyob rau hauv zoo drilling, txiav, engraving nto kho cov ntaub ntawv nyuaj thiab brittle xws li sapphire, iav, pob zeb diamond, semiconductor, ceramics, silicone, thiab lwm yam.Lub high-precision ua ntawm ultrafast laser khoom xav tau ib tug high-precision chiller kom txias. S&A siab zog&ultrafast laser tshuab chiller, nrog kev tswj qhov kub thiab txias txog li ± 0.1 ℃, tuaj yeem muab ceev thiab meej kub tswj rau ultrafast laser, ua tau raws li kev ua haujlwm kub ntawm lub laser ultrafast hauv lub sijhawm thiab xyuas kom cov khoom ruaj khov ntawm ultrafast laser hauv lub sijhawm picosecond. Nws ua haujlwm nrog lub laser ultrafast, ua tiav kev ua tiav hauv pem hauv ntej ntawm kev ua haujlwm zoo.
