KTA Crystal
KTA (potasiomu Titanyle Arsenate, KTiOAsO)4 ) jẹ okuta didan aiṣan ti ko ni aworan ti o jọra KTP ninu eyiti atomọ P ti rọpo nipasẹ Bi. O ni opitika ti ko ni ilaini ti o dara ati awọn ohun-idanimọ elekitiro, fun apẹẹrẹ gbigba idinku pataki ni iwọn iye ti 2.0-5.0 µm, igun-ọrọ gbooro ati iwọn igbohunsafẹfẹ otutu, awọn ohun-elo dielectric kekere.
Ti a ṣe afiwe pẹlu KTP, awọn anfani akọkọ ti KTA pẹlu: alafọwọsi eleemeji-keji ti o ga ju, wefulenti gige ti o ge IR gun, ati gbigba kuru ni 3.5 µm. KTA tun ni iṣẹ iṣe ionic kekere ju ti KTP lọ, eyiti o yọrisi abajade laser giga ti o jẹ ki abirun bibajẹ.
KTA jẹ ohun ti a lo gbajumọ fun ohun elo Pipe Parametric Oscillation (OPO) eyiti o fun ni agbara iyipada agbara to gaju (ju 50%) ti itọsi ina lesa ni awọn lesers ri to.
Kan si wa fun ipinnu ti o dara julọ fun ohun elo rẹ ti awọn kirisita KTA.
