Nonlinear deuterated potassium dihydrogen phosphate (DKDP) and KDP crystals can be used for a variety of applications due to their large nonlinear optical and electro-optical coefficients.

In nonlinear optics these crystals are most commonly used as the second, third and fourth harmonic generators for Nd:YAG and Nd:YLF lasers. In electro-optical applications, DKDP crystals are a fairly common choice for Pockels cell production and they also can be used as Q-switches for Nd:YAG , Nd:YLF, Ti:Sapphire and Alexandrite lasers.

Altechna offers DKDP crystals with deuteration values of up to 98% and custom sizes are available. Please contact our support team with any questions you may have.
