Dab tsi yog qhov txawv ntawm active thiab passive Q-hloov laser?

Q hloov yog dab tsi?

Q-switching yog cov txheej txheem siv hauv tshuab laser los tsim luv luv, siab zog lub teeb pulses. Qhov no tseem ceeb tshwj xeeb hauv kev siv xws li laserKev tshem tawm tattoo, qhov twg lub laser yuav tsum tau tso tawm lub zog nyob rau hauv ib tug luv luv lub sij hawm kom zoo ua txhaum cov number case yam tsis ua puas rau cov tawv nqaij ib puag ncig.Q-hloov Nd:YAG lasersmuaj nyob rau hauv ob lub ntsiab wavelengths: 1064nm thiab 532nm, ua rau lawv haum rau kho txhua hom tawv nqaij thiab tattoos ntawm tag nrho cov xim.

Actively vs. Passively Q-Hloov Lasers

Lub ntsiab sib txawv ntawm actively thiab passivelyQ-hloov lasersyog txoj kev siv los ua kom tiav Q-hloov nyhuv. Ua haujlwm Q-hloov lasers siv cov txheej txheem sab nraud, xws li electro-optic modulator, tswj cov zis laser. Qhov no tso cai rau lub sij hawm meej thiab kev tswj xyuas lub zog, ua rau lub sij hawm mem tes ntawm kwv yees li 5 nanoseconds. Passively Q-hloov lasers, ntawm qhov tod tes, cia siab rau saturable absorbers nyob rau hauv lub laser kab noj hniav kom ua tiav Q-hloov. Thaum cov tshuab passive tej zaum yuav yooj yim dua thiab compact dua, lawv yuav tsis muaj tib theem ntawm kev tswj raws li cov tshuab ua haujlwm.

Qhov zoo ntawm Active Q-Switched Lasers

Actively Q-hloov lasers, xws li covFDA pom zoo Nd:YAG laser, muaj ntau yam zoo hauv kev siv tshuaj kho mob. Lub peev xwm los kho lub sijhawm ntev ntawm cov mem tes thiab lub zog tso tawm tso cai rau cov kws kho mob kom kho cov kev kho mob rau tus neeg mob xav tau. Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv laser tattoo tshem tawm, raws li txawv tattoo xim thiab daim tawv nqaij hom yuav tsum tau sib txawv zog ntau ntau rau kev pom. Lub 1064nm wavelength yog tshwj xeeb tshaj yog zoo rau tattoos tsaus, thaum lub 532nm wavelength yog haum rau sib dua tattoos.

Daim ntawv thov ntawm laser tattoo tshem tawm

Q-hloov Nd:YAG laser yog dav suav hais tias yog tus qauv kub rau laser tattoo tshem tawm. Nws muaj peev xwm xa cov pulses siab zog nyob rau lub sij hawm luv luv, txo qhov kev pheej hmoo ntawm daim tawv nqaij puas tsuaj thaum ua kom zoo rau tattoo number case.Active Q-hloov tshuabntxiv txhim kho qhov muaj peev xwm no, ua rau kev kho mob zoo dua thiab yuav tsum tau siv sijhawm tsawg dua. Cov neeg mob tuaj yeem ua tiav qhov sib zog tattoos, feem ntau nrog kev tsis xis nyob thiab poob qis.

Kev nyab xeeb thiab kev ua tau zoo

Kev nyab xeeb yog thawj qhov kev txiav txim siab rau txhua txoj kev kho mob, thiab FDA-pom zoo Nd:YAG laser yog tsim los nrog qhov no hauv siab. Lub zog Q-hloov tshuab ua kom ntseeg tau tias lub zog xa tawm yog ob qho tib si zoo thiab nyab xeeb rau daim tawv nqaij. Tsis tas li ntawd, qhov ntau yam ntawm 1064nm thiab 532nm wavelengths ua rau cov kws kho mob kho ntau yam xim tattoo thiab hom tawv nqaij, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw kho mob dermatology.

Hauv kev xaus

Hauv cov ntsiab lus, kev nkag siab qhov sib txawv ntawm cov nquag thiab passive Q-hloov lasers yog qhov tseem ceeb rau txhua tus xav txog kev tshem tawm laser tattoo lossis lwm yam kev kho mob ntawm daim tawv nqaij. Active Q-hloov Nd: YAG lasers yog FDA-pom zoo thiab siv cov cuab yeej siv siab heev los muab cov kev daws teeb meem zoo thiab muaj txiaj ntsig los pab koj ua tiav koj cov txiaj ntsig xav tau. Los ntawm kev siv cov khoom tshwj xeeb ntawm 1064nm thiab 532nm wavelengths, cov kws kho mob tuaj yeem muab kev kho tus kheej raws li cov kev xav tau tshwj xeeb ntawm lawv cov neeg mob, ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm txhua qhov kev kho mob.
