Product Details

Characterized by the excelent UV transmission, high damage threshold, and high birefringence, KDP (Potassium Dihydrogen Phosphate) are commonly used commercial NLO materials for doubling, tripling and quadrupling of Nd:YAG laser at room temperature or an elevated temperature. KDP are also excellent electro-optic (EO) crystals with high EO coefficients, thus popularly used as EO modulators and Pockels cells for Q-switched lasers. But KDP crystal has apparent disadvantage of being highly hygroscopic,  therefore, protective coating  and transmitting windows are recommended to secure the polished crystal surfaces.
