Inotakurika pico yechipiri q switch laser muchina

Uchishandisa chiedza chekuputika kwechiedza, iyo yakakwirira-yakasimba laser inopinda muepidermis uye inogona kusvika kumasumbu e pigment mudermis layer. Nekuda kwekuti simba rine nguva pfupi yekuita uye simba racho rakanyanya kukwirira, masumbu epigment anokurumidza kuwedzera uye kuputika mushure mekutora simba repamusoro nekukurumidza. Mushure mokunge zvimedu zvakamedzwa ne macrophages, zvakasvibiswa, uye pigment zvishoma nezvishoma inopera uye inonyangarika.

Iyo picosecond laser ine ultra-short pulse wide inogona kunyatso kuburitsa mafoto-mechanicha mhedzisiro uye kutyora pigment zvimedu kuita zvidimbu zvidiki.
Kuenzaniswa ne nano-scale Q-switched laser, picosecond laser inongoda yakaderera simba kuti iite mhedzisiro.
Zvinotora shoma nhamba yezvidzidzo zvekurapa kuti uwane kurapa kuri nani.
Akasindimara egirinhi nebhuruu ma tattoos anogonawo kubviswa zvinobudirira.
Yakarapwa asi isina kukwana tattoo kubviswa, picosecond laser inogona zvakare kurapa.
Muchigadziro chepigment particle kuparadza, kune kunyanya photothermal uye photomechanical madhara. Kupfupika kwehupamhi hwepulse, ndiko kuderera kwekuita kwekushandura chiedza kuita kupisa. Pane kudaro, iyo photomechanical effect inoshandiswa, saka picoseconds inogona kunyatsopwanya pigment particles, zvichiita kuti zviri nani kubvisa pigment.
