Kodi pali kusiyana kotani pakati pa laser yogwira ndi yokhazikika ya Q-switch?

Kodi Q switch ndi chiyani?

Q-switching ndi njira yomwe imagwiritsidwa ntchito muukadaulo wa laser kupanga ma pulse afupi, opatsa mphamvu kwambiri. Izi ndizofunikira makamaka pamagwiritsidwe ntchito ngati laserKuchotsa tattoo, kumene laser imayenera kumasula mphamvu mu nthawi yochepa kwambiri kuti iwononge bwino tinthu ta inki popanda kuwononga khungu lozungulira.Q-kusintha Nd: YAG lasersakupezeka m'mafunde akuluakulu awiri: 1064nm ndi 532nm, kuwapanga kukhala oyenera kuchiza mitundu yonse ya khungu ndi ma tattoo amitundu yonse.

Mwachangu vs. Passively Q-Switched Laser

Kusiyana kwakukulu pakati pakuchita ndi kungokhala cheteQ-kusintha lasersndi njira yomwe imagwiritsidwa ntchito kukwaniritsa zotsatira za Q-switching. Ma lasers osinthika a Q amagwiritsa ntchito makina akunja, monga electro-optic modulator, kuwongolera kutulutsa kwa laser. Izi zimalola kuwongolera nthawi yolondola komanso kuwongolera mphamvu, zomwe zimapangitsa kuti pakhale nthawi yayitali pafupifupi 5 nanoseconds. Komano, ma lasers osinthika a Q-switched, kumbali ina, amadalira zotengera zokhazikika mkati mwa laser kuti akwaniritse Q-switching. Ngakhale machitidwe osagwira ntchito angakhale osavuta komanso ophatikizana, sangapereke mlingo wofanana ndi machitidwe ogwira ntchito.

Ubwino wa Active Q-Switched Lasers

Ma lasers a Q-switched mwachangu, mongaFDA-yovomerezeka Nd:YAG laser, perekani maubwino ambiri pazachipatala. Kutha kusintha nthawi ya kugunda kwa mtima ndi kutulutsa mphamvu kumalola madokotala kuti azigwirizana ndi zomwe wodwala akufunikira. Izi ndizothandiza kwambiri pakuchotsa ma tattoo a laser, chifukwa mitundu yosiyanasiyana ya ma tattoo ndi mitundu yapakhungu imafunikira mphamvu zosiyanasiyana kuti mupeze zotsatira zabwino. Kutalika kwa 1064nm kumakhala kothandiza kwambiri pama tatoo akuda, pomwe kutalika kwa 532nm ndikoyeneranso kujambula ma tattoo opepuka.

Kugwiritsa ntchito laser tattoo kuchotsa

Laser ya Q-switched Nd: YAG laser imatengedwa kuti ndi muyezo wagolide wochotsa ma tattoo a laser. Imatha kutulutsa mphamvu zamagetsi kwakanthawi kochepa, kuchepetsa chiopsezo cha kuwonongeka kwa khungu ndikuphwanya bwino tinthu tating'ono ta tattoo.Ukadaulo wogwiritsa ntchito Q-switchingkumapangitsanso lusoli, kupangitsa kuti chithandizo chikhale chogwira mtima komanso chofuna magawo ochepa.

Chitetezo ndi mphamvu

Chitetezo ndiye chofunikira kwambiri pazachipatala chilichonse, ndipo laser yovomerezedwa ndi FDA ya Nd:YAG idapangidwa ndikuganizira izi. Njira yogwiritsira ntchito Q-switching imatsimikizira kuti mphamvu zomwe zimaperekedwa zimakhala zothandiza komanso zotetezeka pakhungu. Kuphatikiza apo, kusinthasintha kwa mafunde a 1064nm ndi 532nm kumathandizira madotolo kuchiza mitundu yosiyanasiyana ya ma tattoo ndi mitundu yapakhungu, zomwe zimapangitsa kukhala chisankho chabwino kwambiri kuzipatala za Dermatology.

Pomaliza

Mwachidule, kumvetsetsa kusiyana pakati pa ma lasers a Q-switched ndi okhazikika ndikofunikira kwa aliyense amene akuganiza zochotsa tattoo ya laser kapena chithandizo china chakhungu. Ma laser a Active Q-switched Nd:YAG amavomerezedwa ndi FDA ndipo amagwiritsa ntchito ukadaulo wapamwamba kuti apereke yankho lodalirika komanso lothandiza kukuthandizani kukwaniritsa zomwe mukufuna. Pogwiritsa ntchito mawonekedwe apadera a 1064nm ndi 532nm wavelengths, madokotala amatha kupereka chithandizo chamunthu payekha malinga ndi zosowa za odwala awo, kuwonetsetsa chitetezo ndi mphamvu ya chithandizo chilichonse.
