KTA Crystals
Potassium Titanyl Arsenate crystal is an excellent nonlinear optical crystal used for optical parametric oscillation (OPO). KTA possesses outstanding nonlinear optical and electrooptic coefficients, wide angular and temperature bandwidth, low dielectric constant, and sharp absorption drop in the wavelength range of 2.0-5.0 µm. Due to its lower ionic conductivity, it has a higher damage threshold compared to KTP crystals.
Applications & Features KTA Crystals
» Nonlinear Optical Frequency Conversion
» Solid-State Laser Gain Medium
» Optical Parametric Oscillators (OPOs)
