KTA Crystal
KTA (Potassium Titanyle Arsenate, KTiOAsO)4 ) wani tauraron dan adam ne mara misaltuwa mai kama da KTP wanda aka kunna Atom P ta As. Yana da kyawawan kayan kwalliyar da ba na layi-layi ba da kuma kayan kwalliyar lantarki, misali an rage yawan sha a cikin kewayon bandi na 2.0-5.0 µm, daidaitaccen maɗaukaki da kuma yawan zafin jiki mai ƙarfi, ƙananan ƙwayoyin wuta.
Idan aka kwatanta da KTP, manyan fa'idodin KTA sun haɗa da: mafi girma wanda ba shi da tsari na biyu, mafi girman ragaggen IR na zamani, da ƙarancin sha a 3.5 µm. Hakanan KTA yana da ƙananan aiki na ionic fiye da na KTP, wanda ke haifar da mafi girman laser lalacewa na ƙarancin lalacewa.
KTA ana amfani dashi sosai don aikace-aikacen Optical Parametric Oscillation (OPO) wanda ke ba da babban canji mai ƙarfi (sama da 50%) na radiation laser a cikin ƙananan lasers.
Tuntube mu don mafita mafi kyawun aikace-aikacen ku na lu'ulu'u na KTA.
