Yini alaser?
Okulingana nesiNgisi kwelaser ithi LASER, okusho ukuthi: ukukhanya okukhishwe ngemisebe evuselelwe, okubonisa ngokugcwele ingqikithi yelaser.
Ngokwemigomo ye-layman, i-laser iwuhlobo lokukhanya olusebenza ngokunembile futhi olunokusabalalisa okuphansi kakhulu lapho kukhanya.
Isibonelo, lapho ukwelapha ama-freckles, i-laser iqondise kuphela i-melanin ku-dermis futhi ayithinti ama-molecule amanzi, i-hemoglobin noma ama-capillary esikhumbeni.
Ukuvuselelwa kwesikhumba se-photon, ukususwa kwezinwele ze-photon, kanye ne-E-ray esivame ukukhuluma ngakho konke ukukhanya okunamandla okushaywayo.Igama lesiNgisi lokukhanya okukhulu kwe-pulsed Light lithi Intense Pulsed Light, futhi isifinyezo salo sithi IPL, odokotela abaningi bakubiza ngokuqondile ukuthi i-IPLed pulsed light.
Ngokungafani nama-lasers, ukukhanya okunamandla kwe-pulsed kubonakala ngezinhlobonhlobo zezenzo kanye nokusabalalisa okukhulu phakathi nemisebe.
Isibonelo, lapho ukwelapha imicu ebomvu yegazi (telangiectasia), kungase futhi ngesikhathi esifanayo kuthuthukise izinkinga ezifana nombala wesikhumba obumnyama kanye nezimbotshana ezikhulisiwe.Lokhu kungenxa yokuthi ngaphezu kwama-capillaries, ukukhanya okukhulu kwe-pulsed nakho kuqondise i-melanin ne-collagen ezicutshini zesikhumba.Amaprotheni ayasebenza.
Umehluko Phakathi Kwelaser kanye Nokukhanya Okunamandla Okuphuphumayo
Ukukhanya kwe-pulsed okunamandla kuhluke ngokuphelele ku-laser.Isizathu esiyinhloko ukuthi i-laser ingukukhanya kwe-monochromatic okunobude obungaguquki be-wavelength, kuyilapho ukukhanya okukhulu kwe-pulsed kunobude obuphakathi kuka-420-1200, kunobubanzi obubanzi futhi kulula ukukulungisa.
Okwesibili, ngokungafani nama-lasers agxilile futhi angaguquki, ububanzi be-pulse bokukhanya okukhulu kwe-pulsed ngokuvamile bulungiswa ngokuqhubekayo.
Okokugcina, ukukhanya okushaya ngamandla okunamandla kungakhetha ama-pulse angu-1-3 isikhathi ngasinye, futhi indawo iba nkulu, kuyilapho ama-laser ngokuvamile ane-pulse eyodwa futhi indawo incane.
Izinzuzo abafanele laser kanye okukhulu pulsed ukukhanya
Ukukhanya kwe-pulsed okunamandla kanye ne-laser ngayinye inezinzuzo zayo enqubweni yokwelapha.Izinzuzo zokukhanya okukhulu kwe-pulsed zibonakala ikakhulukazi kulawa maphuzu alandelayo:
(1) Ngokungafani nohlobo olulodwa lwe-laser olukwazi ukwelapha izimpawu ezingasodwa uma kuqhathaniswa, ukulungiswa kobude begagasi bokukhanya okushayeka ngamandla kunquma ukuthi ukukhanya okugobhozayo okunamandla kungaphatha izinkinga ezihlukahlukene zesikhumba.
Njengokususwa kwamafreckle, ukukhishwa kwefilament yegazi elibomvu, ukususwa kwezinwele, ukuvuselelwa kwesikhumba, njll. Ngakho-ke, ukusetshenziswa kobuchwepheshe bokukhanya okunamandla okushaywa umoya kanye nobuchwepheshe obutholakala ekukhanyeni okukhulu kwe-pulsed kungabhekana ngokuphumelelayo nezinkinga ezihlukahlukene zesikhumba, ngaphandle kokukhetha ama-laser amaningi. njengama-lasers.Ukulungiswa okuphelele kwempilo yesikhumba.
(2) I-spectrum ebanzi ayikwazi nje ukuthuthukisa izimbangela eziyinhloko zezinkinga zesikhumba, kodwa futhi ixazulule izici zesibili ezibangela izinkinga zesikhumba.Ingakwazi futhi ukuthuthukisa izimpawu zokuguga kwesikhumba futhi inamandla okuxazulula izici eziningi zezinkinga zesikhumba.
I-Laser kanye nokukhanya okukhulu kwe-pulsed kubalulekile komunye nomunye
Ngaphansi kwezimo ezijwayelekile, ukukhanya okukhulu kwe-pulsed kungasetshenziswa ukwelapha izinkinga ezihlukahlukene zesikhumba.Kodwa-ke, njengoba ukukhanya okukhulu kwe-pulsed kusebenzisa ukukhanya kwe-wavelength ethile ekwelapheni, ngezinye izikhathi ukwelashwa akuphelele.Ngalesi sikhathi, ukwelashwa okuhlosiwe kuyadingeka ngosizo lwe-laser.
