Nd: YAG - Zapamwamba Zolimba Zolimba za Laser
Mafotokozedwe Akatundu
Nd: YAG akadali chida cholimba cha laser chomwe chili ndi magwiridwe antchito abwino kwambiri. Nd: Ma laser a YAG amapopedwa pogwiritsa ntchito flashtube kapena laser diode.
Awa ndi amodzi mwa mitundu yodziwika bwino ya laser, ndipo imagwiritsidwa ntchito pazinthu zosiyanasiyana. Nd: LAG lasers nthawi zambiri imatulutsa kuwala ndi kutalika kwa 1064nm, mu infrared. Nd: LAG lasers amagwira ntchito mumayendedwe othamanga komanso mosalekeza. Pulsed Nd:YAG lasers nthawi zambiri amayendetsedwa mumayendedwe otchedwa Q-switching mode: Chosinthira chowunikira chimayikidwa pabowo la laser kudikirira kusinthika kwakukulu kwa ma ion a neodymium asanatsegule.
Kenako mafunde a kuwala amatha kudutsa patsekeke, ndikuchotsa malo osangalatsa a laser pakusintha kwakukulu kwa anthu. Munjira yosinthira Q iyi, mphamvu zotulutsa za 250 megawatts ndi pulse nthawi ya 10 mpaka 25 nanoseconds zakwaniritsidwa. [4] Ma pulse okwera kwambiri amatha kuwirikiza kawiri kuti apange kuwala kwa laser pa 532 nm, kapena ma harmonics apamwamba pa 355, 266 ndi 213 nm.
Nd: ndodo ya laser ya YAG yopangidwa ndi kampani yathu ili ndi mawonekedwe opindulitsa kwambiri, malo otsika a laser, matenthedwe abwino amafuta komanso kugwedezeka kwamafuta. Ndiwoyenera mitundu yosiyanasiyana yogwirira ntchito (yopitilira, kugunda, Q-switch ndi kutseka mode).
Amagwiritsidwa ntchito kwambiri pama lasers olimba kwambiri, kuwirikiza kawiri komanso kuwirikiza katatu, amagwiritsidwa ntchito kwambiri pofufuza zasayansi, chithandizo chamankhwala, mafakitale ndi magawo ena.
