Mfundo yochotsa tsitsi la laser
Kuchotsa tsitsi kwa laser kumatengera chiphunzitso cha kusankha photothermal action.Tsinde la tsitsi ndi tsinde la tsitsi lili ndi melanin yambiri ndipo laser imatha kulunjika pa melanin pakuchotsa tsitsi moyenera komanso mosankha.Pambuyo pa melanin imatenga mphamvu ya laser, kutentha kumakwera kwambiri, zomwe zimabweretsa kuwonongeka kwa minofu yozungulira tsitsi ndikuchotsa tsitsi.
Ndi chitukuko cha ukadaulo wa laser semiconductor, zinthu zomwe zimagwiritsa ntchito VCSEL monga chida chachikulu zikuwonetsa zabwino zambiri, ndipo zapambana kuzindikirika ndikukondedwa ndi ogula padziko lonse lapansi pankhani ya kukongola kwa laser.Pakadali pano, chida chachikulu chochotsera tsitsi pamsika chimagwiritsa ntchito laser 808nm ngati chida chachikulu.
Pakadali pano, kufunikira kwa msika wa semiconductor laser chip ndikwamphamvu, kotero ndikofunikira kwambiri kuchita kafukufuku wodziyimira pawokha pa semiconductor laser chip.LUMISPOT yautali wa pulse m'lifupi mwake moyimirira mndandandaamagwiritsa ntchito luso lapamwamba lapamwamba la bar kuti apereke maphukusi angapo a laser bar ofukula okhala ndi millisecond pulse width.The gawo utenga mkulu dzuwa disipation mapangidwe, macro channel madzi kuzirala dongosolo (popanda madzi deionized), kuti gawo akhoza kukwaniritsa mkulu kuwala linanena bungwe laser pamene kukhalabe kukula kochepa.
