Kugwiritsa Ntchito ndi Ubwino wa Ukadaulo wa FAC Energy Concentration mu Zipangizo Zochotsera Tsitsi za 808nm

FAC (Fast Axis Collimation) ndi njira yotsogola yolumikizirana ndi maginito. laser Ukadaulo wa kuwala womwe umagwiritsidwa ntchito makamaka pazida zochotsera tsitsi za laser za 808nm semiconductor. Mwa kusintha mawonekedwe otulutsa a laser beam, umathandizira kwambiri magwiridwe antchito ndi magwiridwe antchito a njira zochotsera tsitsi. Ukadaulo uwu ndi chitukuko chachikulu m'munda wamakono wa zida zodzikongoletsera za laser, kupatsa malo okonzera okongola akatswiri njira yochotsera tsitsi yothandiza komanso yotetezeka.

Core PrincIplUkadaulo wa FAC Energy Concentration Technology

Ukadaulo wa FAC umagwiritsa ntchito makina apadera a lenzi ya kuwala kuti uchepetse mwachangu kuwala kwa laser, ndikuyika kuwala koyambirira kosiyana kukhala mphamvu yotulutsa kwambiri. Mu zida zochotsera tsitsi za 808nm, ukadaulo uwu umalola kuti mphamvu ya laser iyang'ane bwino kwambiri pamalo omwe tsitsi limafunidwa, kuchepetsa kutayika kwa mphamvu panthawi yotumizira. Poyerekeza ndi njira zachikhalidwe zotulutsira laser, ukadaulo wa FAC ukhoza kuwonjezera mphamvu yotulutsa mphamvu ndi kupitirira 20%. Kuwongolera mphamvu molondola kumeneku kumathandiza kuti laser ya 808nm wavelength ilowe mkati mwa khungu, kufikira mwachindunji papilla ya dermal, pomwe ikupewa kuwonongeka kwa kutentha kwa minofu yozungulira.

Kusanthula Ubwino Waukadaulo

**1. Kugwira Ntchito Mwachangu Kwambiri**

Ukadaulo wa FAC, wophatikizidwa ndi kutalika kwa 808nm, umapanga liwiro lachangu kwambiri lochotsa tsitsi pamsika. Kukula kwa malo okwana 12×20cm, kuphatikiza ndi kugunda kwamphamvu kwa 10Hz, kumafupikitsa kwambiri nthawi yochizira. Deta yachipatala ikuwonetsa kuti zipangizo zomwe zimagwiritsa ntchito ukadaulo wa FAC zimatha kuchiza malo ochulukirapo a thupi ndi 30% kuposa zida zachikhalidwe panthawi yomweyo, zomwe zimapangitsa kuti zikhale zoyenera kwambiri kuchotsa tsitsi m'malo akuluakulu monga kumbuyo ndi miyendo.

**2. Mphamvu Yokhazikika Kwambiri**

Zipangizo za laser zachikhalidwe zimavutika ndi kusinthasintha kwa mphamvu, pomwe ukadaulo wa FAC umakwaniritsa kutulutsa mphamvu kwa "square wave", kuchotsa mphamvu yayikulu kumayambiriro kwa kugunda kwa mtima ndi kutsika kwa mphamvu kumapeto. Kugawa mphamvu kokhazikika kumeneku kumatsimikizira kuti kugunda kulikonse kufika pamtengo wokhazikika, zomwe zimapangitsa kuti pakhale zotsatira zofanana komanso zokhazikika za chithandizo, kupewa kupsa pakhungu kapena chithandizo chosakwanira chomwe chimachitika chifukwa cha kugawa mphamvu kosagwirizana.

**3. Chitsimikizo Chachiwiri cha Chitetezo ndi Chitonthozo**

Mphamvu zambiri za ukadaulo wa FAC zimathandiza chipangizochi kupeza mphamvu yofanana yochiritsira ndi mphamvu zochepa. Kuphatikiza ndi makina ozizira a safiro, kumasunga kutentha kwa pamwamba pa khungu pafupifupi 5°C. Ukadaulo wa "malo ozizira" uwu umachotsa kutentha ndi ululu wokhudzana ndi kuchotsa tsitsi la laser, zomwe zimapangitsa kuti njira yochizira ikhale yabwino komanso yoyenera kwambiri m'malo ovuta monga bikini ndi nkhope.

**4. Zizindikiro Zambiri**

Kutalika kwa 808nm mwachibadwa kuli ndi mphamvu yabwino kwambiri yolowera pakhungu komanso kulola kuti melanin ilowe. Mukaphatikiza ndi ukadaulo wa FAC, imatha kuchiza mitundu yosiyanasiyana ya tsitsi mosamala komanso moyenera, kuyambira tsitsi lofewa, lofewa mpaka lolimba. Kuphatikiza apo, ukadaulo uwu umasinthasintha kwambiri ku mitundu yosiyanasiyana ya khungu (mtundu wa Fitzpatrick I-VI), kuphatikiza khungu lakuda ndi khungu lowonongeka ndi dzuwa, lomwe ndi lovuta kuchiza ndi laser yachikhalidwe.

**5. Ubwino Waukulu Wachuma Wanthawi Yaitali**

Pogwiritsa ntchito ndodo ya laser yamphamvu ya 2000W yochokera ku Coherent Lasers, pamodzi ndi ukadaulo wa FAC, chipangizochi chimakhala ndi moyo wautali wopitilira ma pulses 50 miliyoni. Kulimba kumeneku kumachepetsa kwambiri ndalama zosinthira zida ndi kukonza malo okonzera kukongola, pomwe kumatsimikizira zotsatira za chithandizo cha nthawi yayitali komanso chokhazikika.

Magwiridwe antchito azachipatala

Muzochitika zachipatala, chipangizo chochotsera tsitsi cha 808nm chokhala ndi ukadaulo wa FAC nthawi zambiri chimachotsa tsitsi pafupifupi kosatha m'njira 4-6 zokha. Tsitsi likamakulanso pambuyo pa chithandizocho limakhala lalitali kwambiri, ndipo tsitsi latsopanolo limakhala lofewa, lopyapyala, komanso ma pores ake amakhala ochepa. Poyerekeza ndi zida zachikhalidwe za IPL kapena laser yokhala ndi mafunde amodzi, chipangizo chochotsera tsitsi cha 808nm chokhala ndi ukadaulo wa FAC chimafupikitsa nthawi yochizira ndi 30%-40% pomwe chimawonjezera kukhutitsidwa kwa makasitomala ndi oposa 25%.

Kuphatikiza kwabwino kwa ukadaulo wa FAC wogwiritsa ntchito mphamvu ndi kutalika kwa 808nm kumayimira luso lamakono laukadaulo wochotsa tsitsi pogwiritsa ntchito laser. Sikuti zimangokhudza magwiridwe antchito ochepa, kupweteka kwakukulu, komanso zizindikiro zochepa za zida zachikhalidwe zochotsera tsitsi, komanso zimapereka njira yopikisana kwambiri yaukadaulo kwa ma salon okongoletsera. Popeza kufunikira kwa ogula kuchotsa tsitsi popanda kupweteka, mwachangu, komanso kwanthawi yayitali kukukulirakulira, ukadaulo uwu wakonzeka kukhala chinthu chodziwika bwino pazida zodzikongoletsera zaukadaulo.
