Tekinoroji yePicosecond laser yakachinja zvakanyanya nyaya dzekurapa runako, ichipa mhinduro dzepamusoro kumatambudziko akasiyana-siyana eganda. Picosecond laser haingogone kushandiswa kubvisa matattoo chete, asi basa rayo rekuchenesa toner rakakurumbirawo.
Picosecond lasers tekinoroji yepamusoro-soro inoburitsa simba re laser rinopenya zvakanyanya mu picoseconds (trillionths yesekondi). Kukurumidza kuburitsa simba re laser kunogona kunanga zvakananga matambudziko eganda, kusanganisira matambudziko eruvara rweganda akadai seganda risina kuenzana uye mavanga matema. Ma laser pulses akasimba anopwanya mapoka e melanin muganda, zvichiita kuti ganda rive rakajeka uye rakachena.
Munguva yekucheneswa kwetoner, kana ikasanganiswa netekinoroji ye picosecond laser, toner inoshanda semushonga wekupisa kweganda, ichitora simba relaser uye ichipisa ganda zvinobudirira. Nokudaro, toner inobatsira kunanga zvidimbu zve melanin nemaronda ane pigment, ichideredza kuoneka kwazvo uye ichisimudzira ganda rakafanana. Izvi zvichavandudza zvakanyanya mhedzisiro yekucheneswa kweganda.
Chimwe chezvakanakira zvikuru zvekushandisa toner pakurapa picosecond laser ndechekuti haipindi muropa. Kusiyana nenzira dzechinyakare dzakadai semakanda emakemikari kana malaser ablative, tekinoroji iyi itsva inoita kuti pave nekusagadzikana uye nguva yekuzorora ishoma. Varwere vanogona kunzwa mhedzisiro yacho nekukasika, pasina kutsvuka kana kutsvuka mushure mekurapwa.
Kuwedzera pakuita kwayo kuchena kweganda, kurapwa ne picosecond laser toner kunokurudzira kugadzirwa kwe collagen. Simba re laser rinopinda mukati meganda, zvichikonzera kuporeswa kwemuviri uye kukurudzira kukura kwe collagen fibers itsva. Izvi zvinoguma nekuvandudzwa kweganda, kusimba uye kudzorerwa kwehujaya.
Kunyange zvazvo mhedzisiro inooneka ichionekwa muchikamu chimwe chete, kurapwa kwakawanda kunowanzo kurudzirwa kuti pave nemhedzisiro yakanaka uye inogara kwenguva refu. Zvichienderana nezvinodiwa nemunhu mumwe nemumwe, zvingadiwa kuti pave nezvikamu zvitatu kusvika zvishanu, zvichiparadzaniswa kwemavhiki maviri kusvika mana pakati pechikamu chimwe nechimwe. Izvi zvichaita kuti ganda richene uye ganda rive nani nekufamba kwenguva.
