KTA Crystal
KTA (Potassium Titanyle Arsenate, KTiOAsO4 ) o se nonlinear opitika tioata tutusa ma KTP lea atom P ua suia e As. E i ai lelei non-linear opitika ma electro-optics meatotino, eg faʻaititia faʻaititia faʻaitiitia i le band band 2.0-5.0 μm, lautele lautele ma vevela vevela bandwidth, maualalo dielectric Constants.
Faʻatusatusa i le KTP, o faʻamanuiaga taua a le KTA e aofia ai: maualuga le lua-faʻasologa nonlinear coefficient, umi IR tipi ese-umi le umi, ma itiiti faʻaaogaina i 3.5 mm. E iai foi le amio maualalo a le KTA nai lo le KTP, e iʻu ai i le maualuga o le laser na mafua ai le faaleagaina.
KTA e sili ona lauiloa faʻaaogaina mo Optical Parametric Oscillation (OPO) talosaga lea e maua ai le maualuga malosi faʻaliliu lelei (i luga o le 50%) o tunable leisa leisa i mautu lasers.
Faʻafesoʻotaʻi mai matou mo le fofo sili mo lau talosaga o KTA tioata.
