Nyob rau hauv lub realms ntawm lub neej sciences thiab biomedical pab kiag li lawm, ib tug laser neeg hlau endowed nrog ib tug "lub hlwb" yog redefining lub precision ntawm lom kev cuam tshuam. Piv txwv li, thaum lub sij hawm fabrication ntawm tag nrho biodegradable polymer cardiovascular stents (xws li cov ua los ntawm PLLA), cov ntaub ntawv exhibits huab cua rhiab heev; Txawm li cas los xij, qhov kub thiab txias hloov pauv tuaj yeem ua rau muaj kev puas tsuaj ntawm cov khoom siv hluav taws xob ntawm cov saw hlau molecular. AI-raws li ultrafast laser systems muaj peev xwm tiag tiag -lub sij hawm tshawb pom cov plasma emissions thiab thermal diffusion gradients ntawm cov npoo txiav, hloov kho lub zog lub hnab ntawv ntawm GHz pulse tawg kom paub meej tias "txias ua" thaum severing sub{{15}tsrusmeric{14} zoo tshaj plaws stent lub hom phiaj biochemical degradation profile thiab radial txhawb zog. Hauv kev tsim cov microfluidic diagnostic chips, AI-tsav laser vuam tshuab rau iav-polymer heterojunctions tuaj yeem saib xyuas cov kev ntxhov siab ntawm lub ntsej muag thiab kev hloov pauv hloov pauv hloov pauv mus rau kev hloov kho kom zoo- kho qhov focal Z- qhov tob thiab vuam zog. Qhov no tso cai rau kev tsim cov pa tawm -dawb, siab -siab- tiv thaiv cov ntsaws ruaj ruaj rau nanoliter- nplai microchannels- tshem tawm cov nplaum nplaum thiab ua kom muaj zog ntau dua - tawm los ntawm cov khoom siv rau thaum ntxov {{28} kev tshuaj ntsuam nc . Nyob rau hauv aerospace sector, tshwj xeeb tshaj yog hais txog lub laser additive manufacturing ntawm refractory alloys (xws li tungsten alloys los yog niobium-silicon-raws li ultra-siab-kub superalloys), Physics-Kev paub txog Neural Networks muaj peev xwm ua kom muaj kev ntxhov siab hauv cov qauv kev sib tw (PINN) ua kom txias txias.
