Tsis ntev los no, laser micromachining kev tshawb fawb pab pawg ntawm Lub Xeev Tshawb Xyuas Kev Tshawb Fawb ntawm lub cev laser, Shanghai lub koom haum ntawm Optics, thiab cov tshuab ua tau zoo, Suav Academy ntawm Kev Tshawb Fawb tau ua rau muaj kev nce qib hauv kev siv cov tshuab ultrafast laser-tawm tsam fluorescent los tiv thaiv cov khoom cuav ntawm cov pob tshab. Pab pawg siv lub tshuab pa hluav taws xob (ultrafast laser) los tsim thiab tswj qhov ceev ntawm lub teeb pom kev tsis xws luag hauv quartz iav, kom thiaj li paub qhov ua los tiv thaiv kev thov cuav ntawm lub teeb pom kev tsis zoo. Cov kev tshawb fawb ntsig txog tau luam tawm nyob rau hauvOpticalMaterialsExpress.
Vim tias nws luv mem tes dav dav thiab siab ncov zog, lub zog ultrafast laser tuaj yeem tsim cov nyhuv uas tsis ua haujlwm. Nws tuaj yeem tsis tsuas hloov kho cov nplaim ntawm cov khoom siv pob tshab xws li hlau, semiconductor, iav tab sis kuj tuaj yeem kho qhov ua tau zoo ntawm cov ntaub ntawv pob tshab. Hauv cov theem thaum ntxov, pab pawg tau siv lub tshuab pa hluav taws xob (ultrafast laser) los tsim lub teeb duab ntawm lub ntsej muag ntawm cov khoom uas tsis yog pob tshab xws li cov hlau thiab cov tshuab hluav taws xob kom paub txog qhov cuav.
Rau kev tiv thaiv sab hauv los ntawm cov ntaub ntawv pob tshab, qhov kev tshawb pom no pom tias thaum ultrafast laser sib cuam tshuam nrog quartz iav, hydrogen-oxygen daim ntawv cog lus ntawm hydroxyl yuav tawg zoo dua, uas ua rau cov pa tsis muaj lub qhov (lub plawv tsis zoo), uas tuaj yeem tawm tau pom fluorescence liab nyob rau hauv muaj zog heev UV irradiation.
Los ntawm kev kho cov mem tes dav thiab lub zog ntawm lub teeb ci ultrafast laser, qhov peb lub qauv tsis zoo peb daim ntawv tuaj yeem sau rau hauv lub iav siab hydroxy quartz los ntawm ultrafast laser. Tus qauv tsis tuaj yeem pom lub ntsej muag nyob rau hauv lub hnub ci, tab sis nws teeb liab fluorescence nyob rau hauv qhov kev zam ntawm lub teeb ci ci ultraviolet, thiaj li paub qhov zais tawm tsam cuav. Ntxiv rau, qhov teeb meem fluorescence center wavelength yog nyob ntawm 650 nm, uas yog qhov tsim nyog rau kev kho mob biomedical kho qhov muag. Yog li, nws xav pom los txhawb cov nplaim hluav taws xob liab uas tsim los ntawm qhov chaw tsis xws luag siv los siv hauv kev kuaj mob biomedical kuaj hauv lub chaw sim nti.
Daim duab. 1 qhov barcode qauv sau los ntawm ultrafast laser nyob rau hauv siab hydroxyl quartz iav yog qhov tsis pom kev hauv (a) hnub ci thiab tawm liab fluorescence nyob rau hauv (b) ultraviolet excitation
Daim duab. 2 (a) raws daim duab schematic ntawm nti nti nyob rau hauv lub siab iav hydroxy quartz iav, thiab (b) lub teeb liab fluorescent tsis zoo ntawm qhov tsis xeb oxygen qhov chaw npaj los ntawm ultrafast laser hauv qhov siab hydroxy quartz iav
