Nd: YAG - Okuhle Kakhulu Solid Laser Material
Incazelo Yomkhiqizo
Nd: I-YAG iseyi-solid-state laser material esebenza kahle kakhulu. Nd:Amalaser e-YAG ampontshwa ngokubona kusetshenziswa i-flashtube noma i-laser diode.
Lezi zingenye yezinhlobo ezivame kakhulu ze-laser, futhi zisetshenziselwa izinhlelo eziningi ezahlukene. Nd:Amalaser e-YAG ngokuvamile akhipha ukukhanya okunobude begagasi obungu-1064nm, ku-infrared. Nd:Amalaser e-YAG asebenza kuyo yomibili imodi yokushaya kanye neqhubekayo. Ama-laser a-Pulsed Nd:YAG ngokuvamile asebenza ngendlela ebizwa ngokuthi i-Q-switching mode: Iswishi yokubona ifakwa ku-laser cavity ilinde ukuguquguquka okukhulu kwabantu kuma-ion e-neodymium ngaphambi kokuthi ivuleke.
Khona-ke igagasi lokukhanya lingadlula emgodini, likhiphe i-laser medium ejabulile ekuguquguqukeni okukhulu kwabantu. Kule modi yokushintshwa kwe-Q, amandla okukhipha ama-megawatts angu-250 kanye nobude be-pulse be-10 kuya ku-25 nanoseconds afinyelelwe.[4] Ama-pulses anamandla aphezulu angase aphindwe kabili ngempumelelo ukuze akhiqize ukukhanya kwe-laser ku-532 nm, noma ama-harmonics aphezulu ku-355, 266 kanye no-213 nm.
I-Nd: Induku ye-laser ye-YAG ekhiqizwe yinkampani yethu inezici zokuzuza okuphezulu, umkhawulo we-laser ophansi, ukuhanjiswa okuhle kwe-thermal kanye nokushaqeka okushisayo. Ilungele izindlela ezahlukahlukene zokusebenza (okuqhubekayo, i-pulse, i-Q-switch kanye nemodi yokukhiya).
Ivamise ukusetshenziswa kuma-laser wesifunda esiqinile se-infrared, ukuphindaphindeka kabili kanye nezicelo zokuphindaphinda kathathu, Isetshenziswa kabanzi ocwaningweni lwesayensi, ekwelashweni, embonini nakweminye imikhakha.
