LiNbO3 Crystal
LiNbO3 (Lithium Niobate) ka aniani he ʻano multifunctional e hoʻopili ana i nā waiwai o ka piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, a me LiNbO3 loaʻa kahi hoʻomehana wai maikaʻi a me ka hoʻomehana kūʻai.
ʻO kekahi o nā mea pono kīlā ʻole optical nonlinear kiʻekiʻe loa, ʻo LiNbO3 ua kūpono no kekahiʻano o nā noi hoʻololi hoʻololi. No ka laʻana, e hoʻohana pālahalaha loa ia ʻo ia nā mau mea pālua no ka wavel> 1 μm a me nā oscillators parametric optical (OPO) i kope ʻia ma 1064 nm e like me nā polokalamu quasi-phase-matched (QPM). Ma muli o kāna nui coefficient EO a me AO, LiNbO3 ʻOi ka hoʻohana ʻana i ka crystal no nā modulators phase, substrguide substrate, nā ʻōpala lele acoustic wafers, a me Q-hoʻololi i nā Nd: YAG, Nd: YLF a me Ti-Sapphire kaila.
LiNbO3 hiki ke loi ʻia i mau kumuwaiwai like ʻole, e like me Er, Pr, Mg, Fe, etc., e hāʻawi i nā waiwai ʻokoʻa. No ka 'aoau, ka paepae poino o MgO: LiNbO3 ua ʻoi aku ma mua o ka pāpālua o ka LiNbO maʻemaʻe3. ^ E Ha yM.
E kāhea mai iā mākou no ka hoʻonā maikaʻi loa no kāu noi o LiNbO3 ʻ .Momi.
