Nd: YAG - Kyawawan Kayan Laser Na Musamman
Bayanin Samfura
Nd: YAG har yanzu shine m-state Laser abu tare da mafi m m yi. Nd: YAG Laser ana yin famfo da kyau ta hanyar amfani da filashi ko diodes.
Waɗannan suna ɗaya daga cikin nau'ikan laser da aka fi sani, kuma ana amfani da su don aikace-aikace daban-daban. Nd: YAG lasers yawanci suna fitar da haske tare da tsawon tsayin 1064nm, a cikin infrared. Nd:YAG Laser suna aiki a cikin yanayin bugun jini da ci gaba. Pulsed Nd: YAG lasers yawanci ana sarrafa su a yanayin da ake kira Q-switching yanayin: Ana saka maɓallin gani a cikin rami na Laser yana jiran matsakaicin juzu'in yawan jama'a a cikin ions neodymium kafin ya buɗe.
Sannan igiyar haske na iya tafiya ta cikin rami, ta lalata matsakaicin Laser mai farin ciki a matsakaicin juzu'in yawan jama'a. A cikin wannan yanayin Q-switched, an sami ikon fitarwa na megawatts 250 da tsawon lokacin bugun jini na 10 zuwa 25 nanoseconds.[4] Za a iya ninka mitar mai ƙarfi da ƙarfi sosai don samar da hasken Laser a 532 nm, ko mafi girman jituwa a 355, 266 da 213 nm.
The Nd: YAG Laser sanda samar da mu kamfanin yana da halaye na high riba, low Laser kofa, mai kyau thermal watsin da thermal girgiza. Ya dace da yanayin aiki iri-iri (ci gaba, bugun bugun jini, Q-switch da kulle yanayin).
Ana amfani da shi a kusa da nisa-infrared m-state Laser, mita ninki biyu da mita tripling aikace-aikace, An yi amfani da ko'ina a kimiyya bincike, likita jiyya, masana'antu da sauran fannoni.
