Dab tsi yog Daim Ntawv Thov Qhov Zoo Thiab Kev Txhim Kho Yav Tom Ntej Ntawm Ultrafast Fiber Lasers?

Ultrafast fiber ntau laser, raws li lub cim tshiab ntawm lasers, tuaj yeem nkag siab tias yog kev sib xyaw ntawm ultrafast technology thiab fiber ntau laser, sib txuas ob qhov zoo ntawm ultrafast laser thiab fiber ntau laser. Kaum xyoo dhau los, ultrafast fiber ntau lasers tseem nyob rau hauv lub tshav pob ntawm kev tshawb fawb yooj yim thiab tau siv nyob rau hauv lub chaw soj nstuam ntawm scientific kev tshawb fawb lub tsev, ua si ib tug tseem ceeb luag hauj lwm raws li ib tug haib tshawb fawb cuab yeej nyob rau hauv lub teb ntawm nonlinear optics, laser spectroscopy, precision kho qhov muag ntsuas, terahertz. , thiab lwm yam kev tshawb fawb. Nrog rau txoj kev loj hlob sai ntawm ultrafast fiber ntau laser manufacturing tshuab, kev txhim kho cov tub ntxhais cov khoom siv xws li twj tso kua mis, ob-clad fiber ntau, fiber ntau grating, thiab lwm yam txheej txheem tsim thiab txo nqi, ultrafast fiber ntau lasers tau tsiv mus rau kev lag luam hauv xyoo tas los no, thiab kev hloov pauv tau siv rau hauv cov ntawv thov kev lag luam.

Ultrafast fiber ntau laser nrog lub ntiaj teb tsis tshua muaj doped fiber ntau raws li lub laser nce nruab nrab tuaj yeem ua tiav miniaturization, kev ua haujlwm siab, thiab tus nqi qis vim qhov loj ntawm thaj chaw thiab yooj yim tshav kub dissipation ntawm fiber ntau, thiab muaj cov txiaj ntsig zoo hauv kev siv tswv yim. Nyob rau tib lub sijhawm, ultrafast lasers muaj qhov tshwj xeeb zoo dua li cov khoom siv ntev-pulse thiab txuas ntxiv lasers. Vim lub sij hawm luv luv ntawm kev sib cuam tshuam ntawm ultrafast-ceev laser thiab cov khoom siv, lub zog tau txhaj tshuaj sai heev rau hauv qhov chaw me me ntawm kev ua, thiab lub zog ceev ceev ceev ceev hloov pauv hom kev nqus hluav taws xob thiab kev txav mus los, ua kom tsis txhob muaj kev cuam tshuam. Kev hloov pauv thiab hloov pauv ntawm lub zog, qhov muaj nyob ntawm lub zog hluav taws xob thiab kev cuam tshuam los ntawm thermal diffusion, thiab kev hloov pauv hauv kev sib cuam tshuam ntawm lub laser thiab cov khoom siv. Kev ua tau zoo hauv kev lag luam xws li precision micro-machining, aerospace, cov khoom siv hluav taws xob, tsheb tsim, thiab photovoltaic zog.

Nws yog tsim nyog hais tias qhov optical zaus zuag system yog Ameslikas tsim los ntawm ib tug tsis tshua muaj neeg loj titanium lub pov haum system, uas yeej tsis tau tsiv. Tam sim no, ua tsaug rau qhov muaj koob meej ntawm ultrafast fiber ntau lasers, uas tau ua zoo strides nyob rau hauv loj thiab tus nqi, qhov Nobel nqi zog technology tau ua rau nws yooj yim dua rau ntau tus neeg. Nyob rau tib lub sijhawm, ultrafast fiber ntau lasers tau nce dav siv hauv biomedical teb, tsis yog rau kev tshawb fawb ntawm lub sijhawm tiag tiag ntawm molecular thiab subcellular dynamics thiab phais tab sis kuj rau cov yam ntxwv ntawm kev puas tsuaj uas tsis yog-ablative, uas tuaj yeem siv rau kev kho mob myopia thiab kho tawv nqaij. Nyob rau hauv xyoo tas los no, qhov tshwm sim ntawm cov fibers tshiab xws li infrared fiber ntau, semiconductor fiber ntau, thiab photonic siv lead ua fiber ntau tau muab cov theem dav rau ultrafast fiber ntau lasers.

Fiber lasers muaj qhov zoo hauv qab no
