Nd: YAG — Rauemi Taiaho Tino Pai
Whakaahuatanga Hua
Nd: Ko YAG tonu te rauemi taiaho totoka me te tino mahi matawhānui. Nd: Ko nga taiaho YAG ka maamata ma te whakamahi i te ngongo hiko, i te ngohe taiaho ranei.
Koinei tetahi o nga momo laser tino noa, ka whakamahia mo te maha o nga tono rereke. Nd: Ko nga taiaho YAG e tuku marama ana me te roangaru 1064nm, i roto i te infrared. Nd: Kei te mahi nga laser YAG i roto i te aratau pupuhi me te haere tonu. Pulsed Nd: Kei te whakahaeretia nga laser YAG i roto i te aratau e kiia nei ko te whakahuri-Q: Ka whakauruhia he pana whatu ki roto i te kohao laser e tatari ana mo te hurihanga nui o te taupori i roto i nga katote neodymium i mua i te whakatuwheratanga.
Na ka rere te ngaru marama i roto i te kohao, ka whakaheke i te reo taiaho hikaka i te hurihanga taupori teitei. I roto i tenei aratau Q-whakawhiti, kua tutuki nga mana whakaputa o te 250 megawatts me te roanga o te 10 ki te 25 nanohekona te roa.[4] Ko nga pupuhi kaha-nui ka pai te whakaruarua ki te whakaputa rama taiaho ki te 532 nm, ki te 355, 266 me te 213 nm.
Ko te rakau laser Nd: YAG i hangaia e to taatau kamupene nga ahuatanga o te painga teitei, te iti o te paepae laser, te pai o te waiariki me te wiri waiariki. He pai mo nga momo momo mahi (te haere tonu, te pupuhi, te Q-whakawhiti me te raka aratau).
Kei te nuinga whakamahia te reira i roto i tata-mamao-infrared taiaho totoka-kāwanatanga, auau rearua me te auau tono toru, Kei te whakamahia whānuitia i roto i te rangahau pūtaiao, maimoatanga hauora, ahumahi me etahi atu mara.
