Puas yog laser muaj kev nyab xeeb rau cov tawv nqaij tawv tawv?

Peb qhov tseeb high-power laser plaub hau tshem tawm tshuab.Nws muaj kev nyab xeeb rau cov tawv nqaij tawv vim nws muaj ob lub wavelengths: ib qho yog 755 nm wavelength & 1064 nm wavelength.Lub 1064 nm wavelength, tseem hu ua Nd: YAG wavelength, tsis yog absorbed los ntawm melanin zoo li lwm cov wavelengths.Vim li no, lub wavelength tuaj yeem kho txhua hom tawv nqaij zoo vim tias nws tso nws lub zog sib sib zog nqus mus rau hauv lub dermis yam tsis muaj kev cia siab rau melanin ua li ntawd.Thiab txij li Nd:YAG yeej tseem ceeb hla lub epidermis, qhov wavelength no yog qhov kev xaiv nyab xeeb rau cov tawv nqaij tsaus nti.

Raws li kev xaiv lub teeb haum txoj kev xav, peb cia lub diode laser tsim los ntawm laser plaub hau tshem tawm tshuab hla ntawm daim tawv nqaij thiab nkag mus rau hauv cov hauv paus plaub hau los ntawm kev kho lub wavelength, lub zog, thiab cov mem tes dav kom paub txog lub hom phiaj tshem tawm cov plaub hau.Nyob rau hauv cov plaub hau follicle thiab plaub hau ncej, muaj plentiful melanin kis ntawm lub follicle matrix thiab txav mus rau cov plaub hau ncej.Thaum cov melanin tau nqus lub zog ntawm laser, nws yuav pom qhov kub thiab txias thiab ua kom puas rau cov ntaub so ntswg nyob ib puag ncig.Ua li no, cov plaub hau tsis xav tau yuav raug tshem tawm tag nrho.
