I-laser ye-KTP iyi-laser yesimo esiqinile esebenzisa ikristalu ye-potassium titanyl phosphate (KTP) njengedivayisi yayo ephindaphinda imvamisa. Ikristalu ye-KTP ihileleka ngomsebe okhiqizwa yi-laser ye-neodymium:yttrium aluminium garnet (Nd: YAG). Lokhu kuqondiswa ngekristalu ye-KTP ukuze kukhiqizwe umsebe ku-spectrum ebonakalayo eluhlaza enobude obungu-532 nm.
I-KTP/532 nm frequency-doubled neodymium:YAG laser iyindlela yokwelapha ephephile nephumelelayo yezilonda zemithambo yegazi ezivamile ezingakhanyi kakhulu ezigulini ezinezinhlobo zesikhumba zeFitzpatrick I-III.
Ubude be-wavelength obungu-532 nm buyindlela eyinhloko yokwelapha izilonda zemithambo yegazi ezingaphezulu. Ucwaningo lubonisa ukuthi ubude be-wavelength obungu-532 nm busebenza kahle okungenani, uma kungengaphezu kwalokho, kune-pulsed dye lasers ekwelapheni ama-telangiectasias obuso. Ubude be-wavelength obungu-532 nm bungasetshenziswa futhi ukususa umbala ongafuneki ebusweni nasemzimbeni.
Enye inzuzo yobude be-wavelength obungu-532 nm yikhono lokubhekana ne-hemoglobin kanye ne-melanin (obomvu nonsundu) ngesikhathi esisodwa. Lokhu kuzuzisa kakhulu ekwelapheni izinkomba ezikhona kuzo zombili ama-chromophores, njenge-Poikiloderma of Civatte noma i-photodamage.
I-laser ye-KTP ihlasela ngokuphephile umbala futhi ifudumale umthambo wegazi ngaphandle kokulimaza isikhumba noma izicubu ezizungezile. Ubude bayo obungu-532nm buphatha ngempumelelo izilonda eziningi zemithambo yegazi.
Ukwelashwa okusheshayo, isikhathi esincane noma esingekho nhlobo sokuphumula
Ngokuvamile, ukwelashwa nge-Vein-Go kungasetshenziswa ngaphandle kokubulala izinzwa. Nakuba isiguli singase sizizwe singakhululekile, inqubo ayibuhlungu kangako.
