Txheej txheem cej luam
Thaum tib neeg hnov lo lus "kua hluav taws xob", lawv feem ntau xav txog kev phom sij. Tab sis qhov tseeb, hluav taws xob hluav taws xob muaj nyob txhua qhov chaw hauv peb lub neej thiab ua haujlwm. Laser hluav taws xob, raws li hluav taws xob hluav taws xob, tsis muaj teeb meem rau tib neeg lub cev raws li kev siv thiab kev tiv thaiv zoo. Kab lus no yuav tshawb txog kev faib hluav taws xob thiab cov yam ntxwv ntawm hluav taws xob hluav taws xob hluav taws xob, thiab qhia txog kev nyab xeeb thiab kev siv dav ntawm Inno Laser's solid-state laser.
Ib. Dab tsi yog hluav taws xob
Radiation hais txog qhov tshwm sim uas lub zog nthuav tawm mus rau qhov chaw nyob ib puag ncig hauv daim ntawv ntawm cov hluav taws xob hluav taws xob lossis cov khoom siv hluav taws xob ceev. Txhua yam khoom nyob rau hauv qhov muaj qhov kub thiab txias tshaj xoom ({1}} degree ) yuav tsim hluav taws xob. Txawm hais tias hluav taws xob nyob txhua qhov chaw, tsis yog txhua qhov hluav taws xob muaj teeb meem rau tib neeg lub cev.
Raws li daim ntawv ntawm hluav taws xob, hluav taws xob tuaj yeem muab faib ua ob pawg: hluav taws xob hluav taws xob thiab hluav taws xob particle. Cov hluav taws xob hluav taws xob muaj xws li ntau qhov sib txawv ntawm cov xov tooj cua, microwaves, infrared rays, pom lub teeb rau X-rays thiab gamma rays: thaum cov hluav taws xob particle muaj xws li high-speed particle ntws xws li electrons, protons, neutrons, alpha hais, beta hais, lwm.
2. Dab tsi yog electromagnetic tawg
Electromagnetic hluav taws xob npog tag nrho cov hluav taws xob propagated nyob rau hauv daim ntawv ntawm electromagnetic tsis, los ntawm xov tooj cua tsis, microwaves, infrared rays uas peb raug nyob rau hauv lub neej txhua hnub, rau high-zog electromagnetic tsis xws li X-rays thiab gamma rays siv nyob rau hauv cov tshuaj thiab kev lag luam.
Raws li lub zog loj ntawm electromagnetic hluav taws xob, nws tuaj yeem muab faib ua ob pawg:
Tsis-ionizing hluav taws xob: tsawg zog, tsis tuaj yeem ionize teeb meem. Hom hluav taws xob no suav nrog xov tooj cua tsis muaj zog, microwaves, infrared rays thiab pom lub teeb. Cov hluav taws xob tsim los ntawm cov khoom siv xws li xov tooj ntawm tes, microwave ncu thiab TV hauv lub neej txhua hnub yog tsis muaj hluav taws xob ionizing.
Ionizing hluav taws xob: Nws muaj lub zog siab thiab tuaj yeem ionize atoms lossis molecules, uas yuav ua rau muaj kev puas tsuaj rau cov teeb meem. X-rays thiab gamma rays yog cov hluav taws xob ionizing thiab feem ntau siv rau hauv kev kho mob duab thiab kev kho hluav taws xob.
3. Laser tawg yog tsis-ionizing hluav taws xob
Laser hluav taws xob yog ib hom tshwj xeeb ntawm hluav taws xob hluav taws xob hluav taws xob uas nws lub wavelength tuaj yeem npog qhov infrared, pom lub teeb lossis ultraviolet ntau yam. Txij li thaum laser feem ntau yog nyob rau hauv qhov tsis-ionizing hluav taws xob ntau, nws yuav tsis ua ionizing puas rau tib neeg lub cev xws li X-rays los yog gamma rays.
Lub uniqueness ntawm laser nyob rau hauv lub siab zog ceev thiab monochromaticity ntawm nws beam. Txawm hais tias lub zog muaj zog, qhov teeb meem ntawm cov hluav taws xob laser tswj tau ntev npaum li qhov ncaj qha lossis cuam tshuam lub teeb raug zam los ntawm ci rau ntawm lub qhov muag lossis tawv nqaij. Qhov no ua rau laser muaj kev nyab xeeb hauv ntau yam kev siv.
4. Kev nyab xeeb thiab daim ntawv thov
solid-state laser siv solid-state media raws li kev tshaj tawm los tsim cov kab hluav taws xob siab. Cov zis hluav taws xob ntawm hom laser no tsis yog-ionizing hluav taws xob, thiab nws lub ntsiab wavelength yog concentrated nyob rau hauv lub teeb pom kev thiab infrared ntau.
Txij li thaum lub laser hluav taws xob ntawm solid-state lasers yog non-ionizing hluav taws xob, nws kuj tsis tshua muaj teeb meem rau tib neeg lub cev. Los ntawm kev siv kom raug thiab kev tiv thaiv kev ntsuas, xws li hnav cov tsom iav tiv thaiv laser thiab tsis txhob cuam tshuam ncaj qha, daim ntawv thov kev nyab xeeb ntawm cov khoom lag luam laser tuaj yeem ua kom ntseeg tau. Tsis tas li ntawd, cov khoom siv hluav taws xob tsis yog tsuas yog muab cov teeb pom kev zoo thiab ruaj khov, tab sis kuj muaj qhov zoo ntawm kev tiv thaiv ib puag ncig thiab kev noj qab haus huv thiab kev nyab xeeb, thiab tsim nyog siv rau ntau yam kev thov.
solid-state thiab ultrafast lasers tau dav siv hauv kev lag luam micromachining, cov khoom siv kho mob muaj txiaj ntsig zoo thiab kev tshawb fawb tshawb fawb vim lawv cov khoom siv hluav taws xob ruaj khov thiab kev ua haujlwm siab. Piv txwv li, nyob rau hauv precision machining, lub tuam txhab lasers tau ua tiav high-precision txiav thiab engraving: nyob rau hauv kev kho mob teb, nws yog ib qho tseem ceeb cov cuab yeej rau kev ua implantable / interventional li: nyob rau hauv lub scientific kev tshawb fawb teb, nws muab kev daws rau high-speed thiab high-resolution photoacoustic hauv vivo imaging.
Cov ntsiab lus
Hauv cov ntsiab lus, hluav taws xob hluav taws xob muaj nyob txhua qhov chaw hauv peb lub neej thiab ua haujlwm. Laser hluav taws xob, uas tsis yog-ionizing hluav taws xob, tsis muaj teeb meem rau tib neeg lub cev raws li kev siv thiab kev tiv thaiv zoo.
