I-KTA Crystal
I-KTA (Potassium Titanyle Arsenate, KTiOAsO)4 ) yi-non-eyearry yekristalu engafaniyo ne-KTP apho atom P ithathelwa indawo nguAs. Inezinto ezintle ezingenanto kunye nomgangatho we-electro-optical, umzekelo, ukunciphisa kakhulu ukufakwa kwinqanaba lomgangatho we-2.0-5.0 µm, ububanzi obubanzi be-angular kunye nobushushu, ii-dielectric eziphantsi.
Xa kuthelekiswa ne-KTP, ezona zibonelelo eziphambili ze-KTA zibandakanya: ukuphakama okulandelelanayo kolungelelwaniso lwe-nonlinear, ixesha elide i-IR's cut-off wavelength, kunye nokufakwa kancinci kwi-3.5 µm. I-KTA ikwanokuhanjiswa kwe-ionic esezantsi kuneso se-KTP, nesiphumo sokonakaliswa komonakalo we-laser ephezulu.
I-KTA ithandwa kakhulu isetyenziselwa isicelo se-Optical Parametric Oscillation (OPO) enika ukuguqulwa kwamandla okusebenza okuphezulu (ngaphezulu kwe-50%) yemitha yelitha e-laser eqinileyo e-lasers.
Nxibelelana nathi ngesona sisombululo sigqibeleleyo sokusetyenziswa kweekristali zeKTA.
