{. Dab tsi yog laser?
A laser is a high-energy beam of light produced by stimulated emission, characterized by properties such as monochromaticity, coherence, and directionality. Laser beams are highly concentrated with extremely high brightness, making them widely used in industrial cutting, medical treatment, and scientific research. However, high-energy lasers also present safety risks, especially potential harm to the eyes and Tawv .
{. kev phom sij ntawm lasers
Qhov phom sij tseem ceeb ntawm cov lasers los ntawm lawv lub zog siab dua, tshwj xeeb hauv kev ua kom lub qhov muag thiab tawv nqaij puas muaj xws li:
1.} qhov muag puas:
Laser Beams tuaj yeem ncaj qha rau lub qhov muag, ua rau muaj kev phom sij lossis tsis pom kev los yog qhov muag tsis pom kev zoo vim tias lawv tsis muaj qhov muag pom kev sib txawv los yog nqus tau cov khoom siv sib txawv tshwj xeeb. .
2.} cov tawv nqaij puas tsuaj:
High-power cov roj yuav hlawv cov tawv nqaij, thiab muaj mob hnyav, lawv tuaj yeem ua rau muaj mob rwj thiab cov ntaub so ntswg.
{. cov qauv siv laser kev nyab xeeb
Txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab ib puag ncig, ob qho tib si thoob ntiaj teb thiab domestic cov qauv kev nyab xeeb tau tsim tsa {{0} tus qauv muaj xws li:
{{0 {}} iec 60825 txuj ci: International ElectroteCort Commission (IEC) tau tsim kho "cov qauv kev nyab xeeb ntawm cov khoom siv roj laser thiab waverength .
2. FDA Laser Kev Nyab Xeeb Ntawv Pov Thawj: Lub u {{{. s}}} Cov txheej txheem kev nyab xeeb muag kom paub meej tias cov khoom siv laser thiab tshuaj siv tsis muaj zog rau tib neeg lub cev.
{. cov khoom siv laser kev nyab xeeb kev nyab xeeb
Txhawm rau txo qis kev nyab xeeb kev nyab xeeb thaum siv laser, nws yog qhov tseem ceeb rau kev siv kev tiv thaiv kev tiv thaiv tsim nyog xws li:
{{0 {}}} saib cov tsom iav tiv thaiv: Nyob ntawm lub wavelength ntawm laser, nws yog ib qho tsim nyog los hnav cov tsom iav ua kom zoo thiab tiv thaiv lub qhov muag los ntawm kev puas tsuaj.
2.} tsim cov chaw nyab xeeb kev nyab xeeb: Cov khoom siv laser yuav tsum tau ua haujlwm tsis pub dhau cov chaw muaj kev nyab xeeb thiab kev nyab xeeb yuav tsum tau siv los tiv thaiv cov neeg tsis tau cai ntawm cov cheeb tsam uas tsis muaj kev tso cai rau cov cheeb tsam uas tsis muaj kev tso cai rau cov cheeb tsam uas tsis raug cai lick.
3. Neeg Teb Xov Tooj: Cov neeg ua haujlwm ntawm cov khoom siv laser yuav tsum tau txais kev cob qhia kev ua haujlwm, txoj kev kho mob ceev, thiab ua kom muaj cov khoom siv hluav taws xob, thiab xyuas kom meej cov khoom siv siv hluav taws xob kom raug}}
4.} Kev kuaj thiab txij nkawm: Kev tshawb xyuas cov haujlwm thiab kev nyab xeeb ntawm cov khoom siv laser kom ntseeg tau tias cov cuab yeej tsis yog kev sib raug zoo lossis puas tsuaj, yog li tsis txhob muaj kev sib tw vim cov khoom tsis ua haujlwm {}}
{. Yuav ua li cas coj Laser Kev Txom Nyem
Txawm hais tias muaj kev nyab xeeb nyab xeeb, Laser raug tshwm sim tuaj yeem tshwm sim, nws yog qhov kev huam yuaj tshwm sim, nws yog qhov xwm txheej ceev ceev} yog qee txoj kev qhia thaum muaj xwm txheej ceev:
1.}} qhov muag hlawv: Yog tias lub npoo laser ua kom tsis txhob muaj lub qhov muag, nrhiav kom tau kev kho mob kom sai li sai tau txo qis kev puas tsuaj .
2.} tawv nqaij hlawv: Yog hais tias daim tawv nqaij yog hlawv los ntawm ib lub qhov txhab, tshem tawm cov dej txias, tsis txhob raug mob hnyav, nrhiav kev kho mob tam sim ntawd.
3.} shutdown xwm ceev: Nyob rau hauv cov ntaub ntawv ntawm laser kev sib tsoo, tam sim ntawd nres cov haujlwm ntawm lub laser thiab xyuas kom cov khoom muaj kev nyab xeeb los tiv thaiv qhov xwm txheej los ntawm kev cuam tshuam .
{.} Xaus
Cov Khoom Siv Laser Ua Si yog cov qauv kev nyab xeeb, tab sis nws cov kev tiv thaiv kev nyab xeeb, nws tsis muaj kev nyab xeeb thiab ua haujlwm kom tsim nyog ntawm cov khoom lag luam .
