Ndeupi musiyano uripo pakati peNd: YAG uye picosecond laser?

Musiyano mukuru ndeye pulse nguva ye laser.

Nd: YAG lasers ari Q-akachinja, zvinoreva kuti vanogadzira mapfupi emagetsi epamusoro-pulses mu nanosecond range.Picosecond lasers, nerumwe rutivi, kubudisa mapurusi mapfupi, anoyerwa nepicoseconds, kana kuti matrillionths esekondi. Iyo yekupedzisira-ipfupi pulse yenguva yepicosecond laser inobvumira kunyatso kunanga kwepigmentation uye tattoo inki, zvichikonzera kukurumidza, kurapa kwakanyanya.

Imwe misiyano yakakosha ndiyo nzira yekuita.

TheNd: YAG laser inoshanda nekupa simba rechiedza chepamusoro-soro munguva pfupi yekupwanya pigment particles muganda, izvo zvinobva zvabviswa zvishoma nezvishoma nekudzivirira kwemuviri. Mukupesana ne,picosecond lasers gadzira iyo photomechanical mhedzisiro inotyora zvakananga pigment zvidimbu kuita zvidiki, zviri nyore-kubvisa zvimedu. Izvi zvinoita kuti picosecond laser ishande zvakanyanya pakubvisa pigment uye ma tatoo, zvinoda kurapwa kushoma.

Panyaya yekuchengeteka uye mhedzisiro, picosecond lasers inowanzoonekwa yakachengeteka kune yakatenderedza ganda tishu. Iyo ipfupi pulse nguva inoderedza kupisa uye kupisa kukuvadzwa paganda, kuderedza njodzi yevanga uye hyperpigmentation. Nd: YAG lasers, ichiri kushanda, inogona kuve nenjodzi yakakwira zvishoma yemhedzisiro nekuda kwekurebesa pulse duration uye yakakwirira kupisa chizvarwa.

Pakupedzisira, sarudzo pakati peNd: YAG uye picosecond lasers zvinoenderana nezvinodiwa uye zvido zvemurwere.

TheNd: YAG laser inozivikanwa zvakanyanya nekuda kwekushanda kwayo mukurapa kwakasiyana siyana mamiriro eganda, nepo picosecond laser inopa yakawedzera uye yakanyatso nzira yekubvisa pigment uye tattoo. Kuonana nachiremba ane hunyanzvi hwedermatologist kana laser nyanzvi kwakakosha kuti uone nzira yekurapa yakanakisa yenyaya yega.
