Uyini umehluko phakathi kwe-laser ye-Q-switch esebenzayo kanye ne-passive?

Kuyini ukushintsha kwe-Q?

I-Q-switching yindlela esetshenziswa kubuchwepheshe be-laser ukukhiqiza ama-pulses amafushane, anamandla amakhulu. Lokhu kubaluleke kakhulu ekusetshenzisweni okufana ne-laserUkususwa kwe-tattoo, lapho i-laser idinga ukukhulula amandla ngesikhathi esifushane kakhulu ukuze iphule ngokuphumelelayo izinhlayiya ze-inki ngaphandle kokulimaza isikhumba esizungezile.Amalaser ashintshiwe ngo-Q Nd:YAGatholakala ngamaza amaza amakhulu amabili: i-1064nm ne-532nm, okuwenza afaneleke ukwelapha zonke izinhlobo zesikhumba nama-tattoos ayo yonke imibala.

Okusebenzayo vs. I-Passively Q-Switched Lasers

Umehluko omkhulu phakathi kokusebenza nokungenzi luthoAmalaser ashintshiwe nge-Qindlela esetshenziselwa ukufeza umphumela wokushintsha i-Q. Amalaser ashintshwayo nge-Q asebenzayo asebenzisa indlela yangaphandle, njengemoduli ye-electro-optic, ukuze alawule ukuphuma kwe-laser. Lokhu kuvumela ukunemba kwesikhathi nokulawulwa kwamandla, okuholela ekushayeni kwenhliziyo okungama-nanosecond angu-5. Ngakolunye uhlangothi, ama-laser ashintshwayo ka-Q ancike ezintweni ezidonsa amanzi ngaphakathi kwendawo ye-laser ukuze afinyelele ekushintsheni kwe-Q. Nakuba amasistimu angenzi lutho angase abe lula futhi aminyene, angase anganikezi izinga elifanayo lokulawula njengamasistimu asebenzayo.

Izinzuzo zama-Laser asebenzayo we-Q-Switched

Ama-lasers ashintshiwe nge-Q, njengeI-FDA egunyazwe i-Nd:YAG laser, nikeza izinzuzo eziningi ezinhlelweni zomtholampilo. Ikhono lokushuna kahle ubude besilinganiso sokushaya kwenhliziyo kanye nokukhipha amandla kuvumela odokotela ukuthi balungise ukwelashwa ngokwezidingo zesiguli ngasinye. Lokhu kusebenza kahle kakhulu ekususeni i-laser tattoo, njengoba imibala ye-tattoo ehlukene nezinhlobo zesikhumba zidinga amazinga ahlukene wamandla ukuze kube nemiphumela emihle. Ubude beza beza be-1064nm busebenza kahle kuma-tattoos amnyama, kuyilapho i-532nm wavelength ifaneleka kakhulu kuma-tattoos alula.

Ukusetshenziswa kwe-laser tattoo ukususwa

Ilaser ye-Q-switched Nd:YAG ibhekwa kabanzi njengezinga legolide lokususwa kwe-laser tattoo. Iyakwazi ukuletha ama-pulses anamandla amakhulu ngesikhathi esifushane, inciphisa ingozi yokulimala kwesikhumba ngenkathi iphula ngokuphumelelayo izinhlayiya zeyinki ye-tattoo.Ubuchwepheshe bokushintsha i-Q obusebenzayoithuthukisa futhi leli khono, okwenza ukwelashwa kusebenze kahle futhi kudinga izikhathi ezimbalwa. Iziguli zingafinyelela ama-tattoos alula kakhulu, ngokuvamile ngokuphatheka kabi kanye nesikhathi sokuphumula.

Ukuphepha nokusebenza ngempumelelo

Ukuphepha ukucatshangelwa okuyinhloko kwanoma iyiphi inqubo yezokwelapha, futhi i-laser ye-Nd:YAG egunyazwe yi-FDA iklanywe inalokhu engqondweni. I-Q-switching mechanism esebenzayo iqinisekisa ukuthi amandla alethwayo ayasebenza futhi aphephile esikhumbeni. Ngaphezu kwalokho, ukuguquguquka kwamaza wamaza angu-1064nm kanye no-532nm kwenza odokotela bakwazi ukwelapha izinhlobonhlobo zemibala ye-tattoo nezinhlobo zesikhumba, okwenza kube ukukhetha okuphezulu emitholampilo yesikhumba.

Ekuphetheni

Kafushane, ukuqonda umehluko phakathi kwama-lasers ashintshiwe kanye ne-Q asebenzayo kubalulekile kunoma ubani ocabangela ukususwa kwe-tattoo tattoo noma okunye ukwelapha kwesikhumba. Amalaser asebenzayo we-Q-switched Nd:YAG agunyazwe yi-FDA futhi asebenzisa ubuchwepheshe obuthuthukisiwe ukuze anikeze isisombululo esinokwethenjelwa nesisebenzayo sokukusiza ukuzuza imiphumela oyifunayo. Ngokusebenzisa izakhiwo eziyingqayizivele ze-1064nm kanye ne-532nm wavelengths, odokotela banganikeza ukwelashwa komuntu siqu okusekelwe ezidingweni ezithile zeziguli zabo, baqinisekise ukuphepha nokusebenza kokwelashwa ngakunye.
