Nd:YAG+YAG一Multi-segment bonded laser crystal

Inkqubo yokudibanisa yeNd:YAGkwayeYAGiikristale linyathelo elibalulekileyo ekulungiseleleni iikristale laser.

Okokuqala, i-high-purity oxide izinto eziluhlaza ezifana ne-aluminium oxide kunye ne-yttrium oxide, kunye nomlinganiselo ofanelekileyo we-doping ion (ezifana ne-neodymium ion) zikhethwa kwaye zixutywe ngokulinganayo. Emva koko, umxube ufudunyezwe kwiqondo lokushisa eliphezulu ukuze unyibilike ube ngumbane. Kule nkqubo, iqondo lokushisa kunye nomoya kufuneka ulawulwe ngokungqongqo ukuqinisekisa ukucoceka kunye nokwakhiwa kweekhemikhali zezinto eziluhlaza.

Emva koko, izinto ezityhidiweyo ezityhidiweyo zipholile ngokuthe ngcembe kwaye zifakwe kwiikristale zebhloko ngokusebenzisa itekhnoloji yokukhula kwekristale. Kule nkqubo, izinga lokukhula kunye neqondo lokushisa le-crystal kufuneka lilawulwe ukuze lifumane iikristali eziphezulu. KubaNd:YAGiikristale, kuyafuneka ukuba kuqinisekiswe ukuhanjiswa okufanayo kweeyoni ze-neodymium kunye noxinzelelo olufanelekileyo lwedoping.

Emva koko i-crystal ibunjwe kwaye iphathwa nge-optical surface ukuze ifumane ubume obufunwayo be-crystal kunye neempawu ezibonakalayo. Kule nkqubo, ukusika, ukupholisa kunye nezinye iinkqubo zifunekayo ukuze kuqinisekiswe ukuba umgangatho ophezulu kunye neempawu ezibonakalayo ze-crystal zihlangabezana neemfuno zokuyila.

Ngokukodwa, ukubunjwa kwendawo kuya kuchaphazela ngokupheleleyo umgangatho wokubambisana. Emva kokuba yonke into igqityiwe, iikristale eziboshiweyo kufuneka zifakwe kwisithando somlilo esishushu. Ngobushushu obuphezulu be-1300 ℃, iimolekyuli phakathi kweziphelo ezimbini zeekristale zinokungena enye kwenye, zenze umphezulu wokudibanisa uqine ngakumbi.
