He aha ka ʻokoʻa ma waena o ka ikaika a me ka passive Q-switch laser?

He aha ka Q kuapo?

ʻO ka Q-switching kahi ʻano hana i hoʻohana ʻia i ka ʻenehana laser e hana i nā puʻupuʻu māmā pōkole a kiʻekiʻe. He mea koʻikoʻi kēia i nā noi e like me ka laserKa wehe ʻana i ka peʻa, kahi e pono ai ka laser e hoʻokuʻu i ka ikehu i loko o ka manawa pōkole loa e wāwahi pono ai i nā ʻāpana inika me ka ʻole e hōʻino i ka ʻili a puni.Q-hoololi Nd:YAG lasersLoaʻa i ʻelua mau lōʻihi nalu nui: 1064nm a me 532nm, no ka mālama ʻana i nā ʻano ʻili āpau a me nā peʻa o nā kala āpau.

ʻO nā Lasers i hoʻololi ʻia me ka Passively Q-Switched

ʻO ka ʻokoʻa nui ma waena o ka actively a me ka passivelyNā lasers hoʻololi Qʻo ia ke ʻano hana e hoʻokō ai i ka hopena Q-switching. Hoʻohana nā lasers Q-switched ikaika i kahi hana o waho, e like me ka modulator electro-optic, e kāohi i ka hoʻopuka laser. Hāʻawi kēia i ka manawa kūpono a me ka mana o ka ikehu, e hopena i ka lōʻihi o ka pulse ma kahi o 5 nanoseconds. ʻO nā lasers passively Q-switched, ma ka ʻaoʻao ʻē aʻe, e hilinaʻi i nā absorbers saturable i loko o ka lua laser e hoʻokō ai i ka hoʻololi Q. ʻOiai ʻoi aku ka maʻalahi o nā ʻōnaehana passive a ʻoi aku ka paʻakikī, ʻaʻole lākou e hāʻawi i ka pae like o ka mana e like me nā ʻōnaehana hana.

Nā Pōmaikaʻi o Active Q-Switched Lasers

ʻO nā lasers Q-hoʻololi ikaika, e like me kaNd:YAG laser apono ʻia e FDA, hāʻawi i nā pono he nui i nā noi lapaʻau. ʻO ka hiki ke hoʻoponopono maikaʻi i ka lōʻihi o ka pulse a me ka hoʻopuka ʻana i ka ikehu e hiki ai i nā kauka ke hoʻololi i nā lāʻau lapaʻau i nā pono o kēlā me kēia maʻi. He mea maikaʻi loa kēia i ka wehe ʻana i ka peʻa laser, no ka mea e koi ana nā kala peʻa like ʻole a me nā ʻano ʻili i nā pae ikehu like ʻole no nā hopena maikaʻi loa. ʻOi aku ka maikaʻi o ka hawewe 1064nm no nā peʻa ʻeleʻele, aʻo ka nalu 532nm i kūpono no nā peʻa māmā.

Hoʻohana no ka wehe ʻana i ka peʻa laser

ʻO ka Q-switched Nd: YAG laser i manaʻo nui ʻia ke kūlana gula no ka wehe ʻana i ka peʻa laser. Hiki iā ia ke hāʻawi i nā puʻupuʻu ikaika kiʻekiʻe i ka manawa pōkole, e hōʻemi ana i ka pōʻino o ka ʻili i ka wā e wāwahi pono ai i nā ʻāpana inika tattoo.ʻenehana hoʻololi Q hoʻololihoʻonui hou i kēia hiki, e hoʻomaikaʻi maikaʻi i ka mālama ʻana a koi i nā kau liʻiliʻi. Hiki i nā maʻi ke loaʻa i nā peʻa māmā loa, pinepine me ka liʻiliʻi liʻiliʻi a me ka manawa haʻahaʻa.

Ka palekana a me ka pono

ʻO ka palekana ka mea e noʻonoʻo nui ai no kekahi kaʻina hana lapaʻau, a ua hoʻolālā ʻia ka laser Nd: YAG i ʻae ʻia e FDA me kēia. ʻO ka hana Q-switching hana e hōʻoia i ka maikaʻi o ka ikehu i hāʻawi ʻia a palekana no ka ʻili. Eia kekahi, ʻo ka versatility o nā hawewe nalu 1064nm a me 532nm hiki i nā kauka ke mālama i nā ʻano kala peʻa a me nā ʻano ʻili, e lilo ia i koho nui no nā keʻena dermatology.

I ka hopena

I ka hōʻuluʻulu manaʻo, ʻo ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o nā lasers Q-switched ikaika a passive he mea koʻikoʻi ia no ka mea e noʻonoʻo ana i ka wehe ʻana i ka peʻa laser a i ʻole nā ​​​​lāʻau ʻili ʻē aʻe. Active Q-switched Nd: YAG lasers ua ʻae ʻia ʻo FDA a hoʻohana i ka ʻenehana holomua e hāʻawi i kahi hopena hilinaʻi a maikaʻi hoʻi e kōkua iā ʻoe e hoʻokō i kāu mau hopena i makemake ʻia. Ma ka hoʻohana ʻana i nā waiwai kūʻokoʻa o nā nalu nalu 1064nm a me 532nm, hiki i nā kauka ke hāʻawi i nā lāʻau lapaʻau pilikino e pili ana i nā pono kikoʻī o kā lākou mau maʻi, e hōʻoia ana i ka palekana a me ka pono o kēlā me kēia lapaʻau.
