BBO Crystal
BBO (ẞ-BaB2O4) o se sili tioata tioata faʻatasi ai ma le tuʻufaʻatasiga o se numera o tulaga ese: faʻalautele le lautele itulagi, lautele vaega-tutusa laina, tele nonlinear fuʻa, maualuga le faʻatonuga pito i lalo, ma sili ona lelei homogeneity. O le mea lea, BBO maua ai se fofo lelei mo eseese nonlinear opitika talosaga e pei o OPA, OPCPA, OPO isi
O loʻo iai foi le lelei o le BBO i luga ole laupepa e talia ai le alualu i luma, o le faʻateteleina o soʻotaga ma faʻaitiitia ai le laititi, e matua talafeagai lelei mo le fesuiaʻiina o taimi ole maualuga poʻo le averesi o le mana e faʻaoga ai le leisa, e pei o le eletise o Nd: YAG, Ti: Sapphire ma Alexandrite leisa laser. BBO o le sili NLO tioata mo le lima lima harmonic tupulaga o Nd: YAG leisa i 213 nm. Lelei leisa lelei utupoto (laiti eseʻesega, lelei faiga tulaga, ma isi) o le ki mo BBO ia maua maualuga liua lelei.
I se faʻaopopoga, tele faʻasalalauga faʻasalalauga tele e pei o fesuiaiga vaega, aemaise lava i UV ituaiga, faia BBO talafeagai lelei mo faʻaluaina faʻaluaina o le Dye, Argon ion ma Copper vapor leisa leisa. E mafai ona maua uma ituaiga 1 (oo-e) ma le ituaiga 2 (eo-e) vaega-faʻapitoa sikoa, faʻateleina ai le numera o lelei mo faʻaaoga eseese o le BBO.
Faʻafesoʻotaʻi mai matou mo le tali sili mo lau faʻaaogaina o tioata BBO.
