Sharaxaada Alaabta

Nd:YVO4 waxay soo saari kartaa IR awood leh oo deggan, cagaar, leysarka buluuga ah oo leh naqshadaynta Nd:YVO4 iyo kiristaalo labanlaabmaya inta jeer. Codsiyada ay u baahan yihiin nashqad aad u kooban iyo qaab-dhismeedka hal-dheer ee loo baahan yahay, Nd:YVO4 waxay muujinaysaa faa'iidooyinkeeda gaarka ah marka loo eego kiristaalo kale oo la isticmaalo.

Faa'iidooyinka Nd:YVO4

● Meesha laasmiga ah oo hooseeya iyo waxtarka jiirada sare
● Qayb weyn oo sii daayo kicin ah oo dhererkeedu yahay dhererka lasing
● Nuugista sare ee baaxadda hirarka dhererka ballaadhkeeda
● Si toos ah uniaxial iyo birefringence weyn ayaa siidaaya leysarka
● Ku-tiirsanaanta hoose ee mawjada dhererka bamgareynta waxayna u janjeertaa wax soo saarka qaab keliya
