Whakaahuatanga Hua

Nd: Ka taea e YVO4 te whakaputa IR kaha me te pumau, nga laser matomato, puru me te hoahoa o Nd: YVO4 me nga tioata rearua auau. Mo nga tono e hiahiatia ana kia nui ake te hoahoa kiato me te putanga aratau-kotahi, Nd:YVO4 e whakaatu ana i ona painga ake ki etahi atu tioata taiaho e whakamahia nuitia ana.

Nga Painga o Nd:YVO4

● He iti te paepae here me te pai o te pikinga teitei
● Whakaongaonga nui whiti-whitinga tukunga i te roangaru roa
● High absorption i runga i te whanui maminga hōkaiipurangi roangaru
● Ko te matao uniaxial me te birefringence nui ka whakaputa i te taiaho polarized
● He iti te ti'aturi i te roangaru pupuhi me te ahu ki te putanga aratau kotahi
