It’s well known that the DKDP crystal is very easy to be damaged by humidity, especially in  environment with high temperature. So ordinary DKDP Pockels cells can not be used in high temperature and high humidity environment, or their service life is very short. After more than two years of continuous technical research, WISOPTIC has successfully developed DKDP Pockels cells that can be used in lasers working in high temperature and high humidity environments. In addition to high temperature and high humidity resistance, the other key specifications of this kind of DKDP Pockels cell are also comparable to similar products made in USA and EU. With this achievement, WISOPTIC is enlarging its technical advantages over other Chinese producers of DKDP Pockels cell.
