KDP and KD*P are nonlinear optical materials, characterized by high damage threshold, good nonlinear optical coefficients and electro-optic coefficients. It can used for doubling, tripling and quadrupling of Nd:YAG laser at room temperature, and electro-optical modulators.


Main Features & Typical Applications

•  High optical damage threshold and high birefringence

•  Good UV transmission

• Electro-optical modulator and Q switches

•  Second, third, and fourth harmonic generation, frequency doubling of Nd:YAG laser

•  High power laser frequency conversion material
