Dab tsi yog qhov txawv ntawm Laser Thiab Lub Teeb?

Ob leegLaserthiab lub teeb yog electromagnetic nthwv dej, thiab lawv muaj ntau yam zoo sib xws, xws li ob qho tib si siv tau rau cov teeb pom kev zoo, muaj ntau yam ntawm wavelengths, thiab ob qho tib si tuaj yeem cuam tshuam thiab cuam tshuam, thiab lwm yam. Tab sis tib lub sijhawm, lasers thiab teeb kuj txawv heev. hauv lwm txoj kev, koj puas paub?

1. Qhov sib txawv ntawm lub hauv paus ntsiab lus ntawm lub teeb emission
Lub laser yog ib tug monochromatic, coherent, thiab directional beam tsim los ntawm ib tug laser. Lub cim ntawm laser yog ua raws li cov hluav taws xob stimulated nyob rau hauv lub laser kab noj hniav. Lub laser ua rau cov khoom hauv cov cuab yeej hloov pauv los ntawm qib qis zog mus rau qib siab zog los ntawm kev siv lub zog. Thaum muaj coob tus hais nyob rau hauv lub xeev siab zog, tsuas yog ib tug tsis muaj zog excitation yuav txhawb tau ib tug loj-scale, yuav luag tag nrho cov photon emission ntawm tib lub zog. tawm, tsim ib lub laser. Lasers yog monochromatic, coherent, thiab linear.

Lub teeb, ntawm qhov tod tes, yog ib qho dav-spectrum, incoherent qhov chaw ntawm lub teeb, feem ntau yog tsim los ntawm txoj kev xws li resistive hlau, roj paug, thiab semiconductors. Hauv cov qauv teeb pom kev zoo no, tom qab cov khoom tsim hluav taws xob tsim hluav taws xob thiab tso tawm, lawv yuav tawg mus rau hauv txhua qhov kev qhia. Yog li ntawd, cov photons uas tsim los ntawm lub teeb muaj ntau zaus thiab theem, thiab cov ces kaum sib txawv tsis sib xws, yog li nws yog ib qho nyuaj rau kev lav phib xaub thiab linear directionality.

2. Qhov txawv ntawm kev phom sij
Vim hais tias lub laser yog generated nyob rau hauv lub resonant kab noj hniav, qhov kho qhov muag txoj kev txawv me me heev, thiab lub attenuation poob nyob rau hauv lub resonant kab noj hniav kuj yog heev me me, yog li ntawd lub laser muaj siab monochromaticity thiab directivity. Lub laser tuaj yeem hloov kho ntxiv kom muaj kev siv lub laser siab, uas tuaj yeem mloog zoo rau lub zog thiab kis tau los ntawm huab cua. Nyob rau hauv cov xwm txheej luv luv, lub laser tuaj yeem pom qhov siab ntawm kev ua kom pom tseeb, uas ua rau muaj kev phom sij heev.Lub teeb beam txawv, vim hais tias nws tsis tuaj yeem kov yeej cov nyhuv polarization thiab tawg, cov nqaj tsis meej txaus, qhov pom kev deb yuav luv dua, thiab qhov chaw tsis zoo li qhov chaw laser. Kev phom sij tsawg heev.

3. Optical fais fab sib txawv
Lasers muaj lub teeb tso zis ntau dua li cov teeb. Stimulated emission ntawm hluav taws xob ua rau ib tug loj nce nyob rau hauv lub zog ntawm photons nyob rau tib lub sij hawm, mus txawv tebchaws nyob rau hauv ib qho kev taw qhia, yog li ua rau kom cov kev siv ntawm lub laser beam tsim los ntawm lub laser. Lub photons ntawm lub teeb yog generated los ntawm spontaneous hluav taws xob, cov kev taw qhia yog random, thiab lawv kis nyob rau hauv ib tug sib txawv lub xeev. Peb zoo li lub teeb mos.

4. Siv qhov sib txawv
Laser tuaj yeem siv rau kev phais mob myopia, uas yog txoj hauv kev zoo thiab ceev los kho mob myopia siab. Nyob rau tib lub sijhawm, laser tuaj yeem tshem tawm cov caws pliav, moles, thiab freckles, kho cov tawv nqaij elasticity, thiab ua kom tawv nqaij smoother. Nws tuaj yeem siv rau hauv kev txiav, vuam thiab lwm yam lag luam. Kev siv, kev sib txuas lus kho qhov muag, kev ruaj ntseg, teeb pom kev zoo thiab lwm yam kev siv yog qhov dav dua qhov teeb pom kev zoo.
