Laser tiv thaiv tsom iavyog cov cuab yeej tiv thaiv tseem ceeb uas siv los tiv thaiv lub qhov muag los ntawm kev puas tsuaj ntawm laser tawg. Nrog rau kev siv tshuab laser dav dav hauv kev lag luam, tshuaj, kev tshawb fawb tshawb fawb, thiab lwm yam, nws yog ib qho tseem ceeb los xyuas kom meej qhov kev nyab xeeb ntawm cov iav tiv thaiv laser.
1. Lub luag haujlwm thiab qhov tseem ceeb ntawmlaser tiv thaiv tsom iav
Laser yog ib tug high-zog electromagnetic yoj hluav taws xob nrog ib tug wavelength ntawm ultraviolet mus infrared. Lasers muaj cov yam ntxwv ntawm monochromaticity, coherence, directionality thiab siab brightness, thiab yog dav siv nyob rau hauv industrial ua, kuaj mob thiab kev kho mob, kev tshawb fawb thiab lwm yam kev lag luam. Txawm li cas los xij, cov hluav taws xob laser kuj muaj peev xwm ua rau tib neeg lub cev, tshwj xeeb tshaj yog kev puas tsuaj loj tshaj plaws rau lub qhov muag.
Laser hluav taws xob yuav ua rau thermal puas, photochemical puas thiab ionizing hluav taws xob puas rau lub qhov muag. Kev puas tsuaj cua sov yog tshwm sim los ntawm kev nqus ntawm lub zog laser los ntawm lub qhov muag cov ntaub so ntswg, ua rau lub zos kub nce, ua rau cov protein denaturation thiab cov ntaub so ntswg kub hnyiab. Photochemical kev puas tsuaj yog tshwm sim los ntawm lub zog photon ntawm laser hluav taws xob txaus los ua cov tshuaj tiv thaiv photochemical thiab rhuav tshem cov roj ntsha macromolecules ntawm cov hlwb. Ionizing hluav taws xob puas tsuaj yog tshwm sim los ntawm high-zog laser hluav taws xob ionizing atoms los yog molecules, ua dawb radicals thiab ions, yog li ua puas hlwb.
Yog li ntawd, nws yog ib qho tseem ceeb rau hnav kom haumlaser tiv thaiv tsom iavthaum ua haujlwm hauv laser. Laser tiv thaiv iav tuaj yeem thaiv cov hluav taws xob laser zoo nyob rau hauv ib qho kev sib txawv wavelength thiab tiv thaiv ob lub qhov muag los ntawm kev puas tsuaj. Lasers ntawm ntau hom thiab lub zog theem yuav tsum tau laser tiv thaiv iav ntawm txawv specifications. Xaiv qhov zoo laser tiv thaiv tsom iav thiab ua kom lawv cov kev ua tau zoo yog qhov tseem ceeb kom muaj kev nyab xeeb ntawm tus neeg teb xov tooj lub qhov muag.
2. Kev faib tawm thiab cov qauv ntawmlaser tiv thaiv tsom iav
Raws li cov kev cai ntawm International Organization for Standardization (ISO),laser tiv thaiv tsom iavtuaj yeem muab faib ua pawg hauv qab no raws li lawv lub peev xwm tiv thaiv:
Qib L1: Muaj feem xyuam rau cov lasers pom tsawg dua 1mW
Qib L2: Muaj feem xyuam rau cov lasers pom ntawm 1-5mW
Qib L3: Muaj feem xyuam rau cov lasers pom ntawm 5-500mW
