Nd: YAG - Sesebediswa se setle sa Laser e tiileng
Tlhaloso ea Sehlahisoa
Nd: YAG e ntse e le lisebelisoa tsa laser tse tiileng tse nang le ts'ebetso e phethahetseng ka ho fetesisa. Nd: Li-lasers tsa YAG li pompeloa ka pono ka ho sebelisa flashtube kapa laser diode.
Ena ke e 'ngoe ea mefuta e atileng haholo ea laser,' me e sebelisoa lits'ebetsong tse ngata tse fapaneng. Nd:YAG lasers hangata e ntša khanya e nang le leqhubu la bolelele ba 1064nm, ho infrared. Nd: Li-lasers tsa YAG li sebetsa ka mokhoa oa pulsed le o tsoelang pele. Pulsed Nd:YAG lasers hangata e sebetsoa ka mokhoa oo ho thoeng ke Q-switching mode: switch optical e kenngoa ka har'a laser cavity e emetse palo e kholo ea batho ba fetohang li-ion tsa neodymium pele e bula.
Ebe leqhubu la leseli le ka tsamaea ka har'a sekoti, la theola sebaka sa laser se thabileng ka bongata bo boholo ba batho. Ka mokhoa ona oa Q-switched, matla a tlhahiso ea 250 megawatts le pulse durations ea 10 ho 25 nanoseconds a fihletsoe.[4] Maqhubu a matla a phahameng a ka 'na a imena habeli ho hlahisa leseli la laser ho 532 nm, kapa li-harmonics tse phahameng ho 355, 266 le 213 nm.
The Nd: YAG laser rod e hlahisoang ke k'hamphani ea rona e na le litšobotsi tsa phaello e phahameng, moeli o tlase oa laser, conductivity e ntle ea mocheso le ho sisinyeha ha mocheso. E loketse mefuta e fapaneng ea mekhoa ea ho sebetsa (e tsoelang pele, pulse, Q-switch le mokhoa oa ho notlela).
E sebelisoa hangata ho li-laser tse tiileng tsa boemo bo haufi-ufi-hole-hole, ho pheta-pheta habeli le makhetlo a mararo, E sebelisoa haholo lipatlisisong tsa mahlale, kalafo ea bongaka, indasteri le likarolo tse ling.
