I-KTA Crystal
I-KTA (Potassium Titanyle Arsenate, KTiOAsO4 ) iyi-crystal engabonakali ye -lineline efana ne-KTP lapho i-athomu P ithathelwa indawo yi-As. Inezakhiwo ezinhle ezingekho emgqeni we-optical ne-electro-optical, isb ukunciphisa kakhulu ukumuncwa ebangeni lebhande le-2.0-5.0 broadm, okubanzi kwe-angular and lokushisa band, ama-dielectric aphansi.
Uma kuqhathaniswa ne-KTP, izinzuzo eziphambili ze-KTA zifaka phakathi: ukuphakama kwe-oda lesibili kwe-nonlinear, i-IR wave-off wavelength ende, kanye nokufakwa kancane ku-3.5 µm. I-Kta futhi inokusebenza okuphansi kwe-ionic kunalokho kwe-KTP, okuphumela ekunciphiseni umngcele wokulimala we-laser.
I-KTA isetshenziselwa kakhulu isicelo se-Optical Parametric Oscillation (OPO) esinika amandla amaningi okuguqula amandla (ngaphezulu kwe-50%) yemisebe ye-laser ethandekayo kuma-lasers aqinile.
Xhumana nathi ngesixazululo esihle kakhulu sohlelo lwakho lokusebenzisa amakristalu we-KTA.
