Nd: YVO4 Crystal
Nd: YVO4 (ʻO Neodymium-doped Yttrium Vanadate) kekahi o nā mea pono loa i hāʻawi ʻia i nā mea kūʻai aku pono no nā lasers solid-died-pumps, ka mea no ka laser me ka mana haʻahaʻa haʻahaʻa a waena paha. Ma ka hoohauau, Nd: YVO4 he ʻoi aku ka maikaʻi ma mua o Nd: YAG no ka hoʻopuka ʻana i nā pālima haʻahaʻa haʻahaʻa ma nāʻaoʻao i paʻa i kahi lima a i ʻole nā mea hoʻohui compact. I kēia mau noi, Nd: YOV4 aia kekahi mau pono ma luna o Nd: YAG, e laʻa ka nui o ka hoʻohuihui nui ʻana o ka laser irradiation a me ka pālahalaha nui ʻana i ka papa.
Nd: YVO4 kahi koho maikaʻi no ka hoʻopuka polarized koʻikoʻi ma ka 1342 nm, ʻoi aku ka ikaika o ka laina emission ma mua o nā mea e pili ana i ka koho. Nd: YVO4 hiki ke hana pū me kekahi mau kristal nonlinear me ka coefficient kiʻekiʻe o NLO (LBO, BBO, KTP) e hana ai i nā kukui mai kahi kokoke i ke kīleʻa i ke kukui, uliuli, a me nā ʻā UV paha.
E kāhea iā mākou no ka hoʻonā maikaʻi loa no kāu noi o Nd: YVO4 ʻ .Momi.
