Lub ntiaj teb no ntawm laser technology yog ib qho kev sib xyaw ua ke ntawm kev tsim kho tshiab, precision, thiab muaj peev xwm txaus ntshai uas xav tau kev hwm thiab ua tib zoo saib xyuas. Ze-infrared (NIR) lasers, nrog rau lawv cov teeb pom kev tsis tau muaj zog, ua piv txwv qhov dichotomy no. 1064nm, 1070nm, thiab 1080nm, lawv cov kev siv sib txawv, cuam tshuam txog kev phom sij, thiab cov kev ntsuas tseem ceeb rauxyuas kom muaj kev nyab xeebntawm cov neeg ua haujlwm nrog lawv. peb tuaj yeem nkag siab tob txog qhov cuam tshuam tseem ceeb ntawm NIR lasers muaj nyob thoob plaws ntau qhov chaw thiab qhov tseem ceeb ntawm kev saib xyuas kev nyab xeeb ua ntej thaum siv lawv lub peev xwm.
Ze-Infrared (NIR) Lasers:
Ze-infrared (NIR) lasers ua haujlwm ntawm wavelengths me ntsis ntev dua li pom lub teeb, feem ntau nyob rau hauv thaj tsam ntawm 700 nanometers (nm) txog 1500 nm. NIR lasers muaj ntau yam kev siv hauv ntau yam xws li kev sib txuas lus, kev ua cov ntaub ntawv, kev kho mob, thiab kev tshawb fawb tshawb fawb.
Invisibility thiab Qhov Muag Hazards:
NIR lasers raug suav hais tias pom tsis pom vim tias lawv cov wavelengths poob sab nraum qhov pom spectrum rau tib neeg. Txawm hais tias cov lasers tsis pom ntawm qhov muag liab qab, lawv tseem tuaj yeem ua rau muaj kev phom sij rau tib neeg lub qhov muag thiab tawv nqaij. Tib neeg lub qhov muag yog qhov tshwj xeeb tshaj yog rau cov hluav taws xob laser, tsis hais seb nws puas pom lossis tsis pom. Thaum raug NIR laser lub teeb siab, lub qhov muag yuav raug kev puas tsuaj rau lub retina, ua rau tsis pom kev mus tas li lossis qhov muag tsis pom.
Piv txwv ntawm NIR Laser Wavelengths:
1064nm: Qhov wavelength no feem ntau siv rau hauv kev lag luam xws li laser txiav, vuam, thiab drilling. Nws kuj tseem siv rau hauv cov txheej txheem kho mob xws li dermatology thiab ophthalmology.
1070nm: Cov lasers no yog siv rau ntau yam kev siv kho mob, nrog rau cov ntaub so ntswg ablation, photocoagulation, thiab laser phais.
1080nm: Qhov wavelength no feem ntau ua haujlwm hauv fiber optics kev sib txuas lus, laser rangefinders, thiab spectroscopy.
Daim ntawv thov ntawm NIR Lasers:
NIR lasers pom ntau daim ntawv thov thoob plaws kev lag luam sib txawv vim lawv cov khoom tshwj xeeb. Qee qhov kev siv feem ntau suav nrog:
Kev sib txuas lus: NIR lasers yog ib qho tseem ceeb rau fiber ntau optic kev sib txuas lus rau kev xa cov ntaub ntawv nyob rau qhov ntev nrog tsawg tsawg.
Cov Khoom Siv Ua Haujlwm: Kev lag luam xws li kev tsim khoom, tsheb, thiab aerospace siv NIR lasers rau kev txiav, vuam, thiab kos ntau yam ntaub ntawv xws li hlau, yas, thiab ceramics.
Kev Kho Mob: Hauv kev kho mob, NIR lasers tau ua haujlwm rau cov txheej txheem xws li coagulation, phais, dermatology, thiab txawm tias yog cov cuab yeej kuaj mob uas tsis muaj kev cuam tshuam hauv cov txheej txheem duab.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: NIR lasers ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb tshawb fawb rau kev siv xws li spectroscopy, fluorescence imaging, microscopy, thiab analytical chemistry.
Laser phom sij thiab kev nyab xeeb ntsuas:
Qhov muag phom sij: Raws li tau hais dhau los, NIR lasers tuaj yeem ua rau lub qhov muag puas tsuaj loj yog tias tsis ua raws li kev ntsuas kev nyab xeeb. Qhov no suav nrog kev kub nyhiab ntawm qhov muag, tsis pom kev mus tas li, thiab txawm tias qhov muag tsis pom.
Kev phom sij ntawm daim tawv nqaij: NIR lasers kuj tuaj yeem ua rau muaj kev pheej hmoo rau ntawm daim tawv nqaij, ua rau kub hnyiab lossis cov ntaub so ntswg puas thaum raug ncaj qha rau cov kab hluav taws xob siab.
Reflections: Reflective nto tuaj yeem nthuav dav NIR laser beams thiab ua rau muaj kev pheej hmoo ntawm kev raug mob. Kev ceev faj kom raug yuav tsum tau coj los tiv thaiv qhov xwm txheej tsis xav txog.
Safety Eyewear: Hnav tsim nyoglaser tsom iav tsom iavuas thaiv qhov tshwj xeeb wavelength ntawm lub laser yog qhov tseem ceeb thaum ua haujlwm nrog NIR lasers. Cov tsom iav no yuav tsum ua raws li cov qauv kev nyab xeeb uas cuam tshuam thiab muab kev txauskev tiv thaivrau qhov muag.
Tswj Ib puag ncig: Kev khiav hauj lwm NIR lasers nyob rau hauv kev tswj ib puag ncig nrog interlocks, ceeb toom cov cim, thiab xaiv qhov chaw muaj kev ruaj ntseg yuav pab txo kom txhob muaj kev huam yuaj tshwm sim los ntawm laser hluav taws xob.
Kev cob qhia thiab txheej txheem: Kev cob qhia kom raug raulaser kev ruaj ntseg raws tu qauv, suav nrog kev tuav, kev saib xyuas, thiab cov txheej txheem xwm txheej ceev, yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog NIR lasers.
Xaus:
Hauv kev xaus, thaum NIR lasers yuav pom tsis tau ntawm qhov muag liab qab, lawv tseem ua rau muaj kev phom sij rau tib neeg lub qhov muag thiab tawv nqaij. Nws yog ib qho tseem ceeb kom nkag siab txog cov kev pheej hmoo uas cuam tshuam nrog NIR laser raug thiab siv cov kev ntsuas kev nyab xeeb nruj kom ntseeg tau tias kev noj qab haus huv ntawm cov tib neeg ua haujlwm nrog cov lasers no. Los ntawm kev ua raws li cov txheej txheem kev nyab xeeb kom raug, sivcov khoom tiv thaiv tsim nyog, thiab tswj kev ceev faj txog kev nyab xeeb ntawm laser, qhov muaj peev xwm txaus ntshai ntawm NIR lasers tuaj yeem txo tau zoo, tso cai rau kev nyab xeeb thiab siv tau zoo ntawm cov thev naus laus zis no thoob plaws ntau qhov kev lag luam.
