Detail
Introduction to KDP/DKTP DKDP & KDP crystal potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (DKDP) have low nonlinear coefficients, but they are widely used due to their superior ultraviolet transmission, high damage threshold, and high birefringence coefficient. In a variety of industrial uses. These two crystals are usually used to make Nd:YAG lasers for second, third, and quadruple frequency devices (at room temperature)
