LBO Crystal
LBO (LiB3O5) iri mhando yeasinga-mutsara wekupenya makristasi ane yakanaka ultraviolet transmittance (210-2300 nm), yakakwira laser kukuvadza chikumbaridzo uye yakakura inoshanda frequency yakapetwa kaviri kukwana (ingangoita katatu nguva yeKDP kristalo). Saka LBO inowanzo shandiswa kugadzira yakakwirira simba wechipiri uye wechitatu harmonic laser mwenje, kunyanya kune Ultraviolet lasers.
LBO ine hombe band band uye pachena nzvimbo, yakakwirira isiri-mutsara coupling, yakanaka yemakemikari uye mehendi zvivakwa. Aya maficha anoita kuti iyi kristallist ikwanise yeanternational parametric process (OPO / OPA) uye noncritical phase coup (NCPM), futi.
Bata isu kune mhinduro yakanakisa yekushandisa kwako maLBO makristasi.
