Crystals are also widely used for electro-optical applications as Q-switches for Nd:YAG, Nd:YLF, Ti:Sapphire and Alexandrite lasers, as well as for Pockels cells. The most commonly used electro-optical crystal is DKDP with a deuteration more than 98%. These crystals are grown by a water-solution method and can be grown up to very large sizes. Therefore, they are as low-cost and large-size finished non-linear components available. For frequency-doubling (SHG) and -tripling (THG) of Nd:YAG laser at 1064 nm, both type I and type II phase-matchings can be employed for Nonlinear single crystals KDP and DKDP. For frequency - quadrupling (4HG, output at 266 nm) of Nd:YAG laser KDP crystal is normally recommended.
We offer large aperture KDP crystals (up to 400x400mm and 10- 50mm length).
