tioata BBO

O le BBO o se tioata fou e faʻaluaina le faʻafefe o le ultraviolet.O se tioata fa'a-uniaxial le lelei, fa'atasi ai ma fa'asino fa'asino masani (leai) e sili atu nai lo fa'asino fa'asino fa'apitoa (ne).E mafai ona maua le fa'afetauiga o vaega I ma le ituaiga II e ala i le fa'aogaina o tulimanu.

    O le BBO o se tioata faʻaluaina faʻaluaina o le ultraviole fou. O se tioata uniaxial le lelei, faʻatasi ai ma faʻamaufaʻailoga masani (leai) e sili atu nai lo faʻailoga faʻapitoa (ne).E mafai ona maua le fa'afetauiga o vaega I ma le ituaiga II e ala i le fa'aogaina o tulimanu.
    O le BBO o se tioata NLO lelei mo le lona lua, tolu ma le fa o augatupulaga o le Nd: YAG lasers, ma le tioata NLO sili ona lelei mo le lona lima o augatupulaga i le 213nm.Fa'aliliuga lelei o le sili atu i le 70% mo le SHG, 60% mo le THG ma le 50% mo le 4HG, ma le 200 mW gaioiga i le 213 nm (5HG) ua maua, i le faasologa.
    O le BBO foi o se tioata lelei mo le intracavity SHG o le malosi maualuga Nd: YAG lasers.Mo le intracavity SHG o se acousto-optic Q-switched Nd: YAG laser, sili atu i le 15 W averesi malosiaga i le 532 nm na gaosia e se AR-coated BBO tioata.Ina ua pamuina e le 600 mW SHG gaioiga o se auala-loka Nd: YLF leisa, 66 mW galuega faatino i le 263 nm na gaosia mai le Brewster-angle-otiina BBO i se lua resonant faaleleia fafo.
    E mafai foi ona fa'aoga BBO mo talosaga EO.BBO Pockels sela po'o EO Q-Switches e fa'aaogaina e sui ai le tulaga polarization o le malamalama e ui atu i ai pe a fa'aoga le voltage i le eletise o tioata eletise-optic pei ole BBO.Beta-Barium Borate (β-BaB2O4, BBO) faʻatasi ai ma faʻataʻitaʻiga lautele manino ma vaega faʻafetaui laina, tele nonlinear coefficient, maualuga faʻaleagaina faitotoʻa ma sili atu opitika homogeneity ma electro-optical meatotino e maua ai avanoa faatosina mo le eseese nonlinear opitika talosaga ma talosaga electro-optic.
    Fa'ailoga o BBO Crystals:
    • Va'aiga lautele fa'atusa fa'atusa mai le 409.6 nm i le 3500 nm;
    • Itulau lautele felauaiga mai le 190 nm i le 3500 nm;
    • Lapo'a lelei lona lua fa'atupu fa'atasi (SHG) e tusa ma le 6 taimi sili atu nai lo le KDP tioata;
    • Tulaga maualuga le faaleagaina;
    • Tulaga tutusa maualuga ma le δn ≈10-6/cm;
    • Lautele vevela-bandwidth e tusa ma le 55℃.
    Fa'aaliga taua:
    O le BBO e maualalo le faʻafefe i le susu.Ua fautuaina tagata fa'aoga e tu'uina atu tulaga mago mo le fa'aogaina ma le fa'asaoina ole BBO.
    O le BBO e vaivai ma o lea e manaʻomia ai le faʻaeteete e puipuia ai ona foliga faʻalelei.
    Pe a manaʻomia le faʻaogaina o le tulimanu, faʻamolemole ia manatua o le taliaina o le BBO e laʻititi.
