DKDP Pockels Cells

March 8, 2021
DKDP or KD*P crystals have high electro-optic coefficients and good transmission at 0.3 to 1.1µm, which makes well-suited for pockels cells Q-switches applications.

Hangzhou Shalom EO offers Pockels Cells made from DKDP(KD*P) crystals. DKDP crystals feature high electro-optic coefficients high transmission from 0.3 to 1.1µm, which makes them well-suited for pockels cells Q-switches applications. The deuteration rate of DKDP crystals that are selected to manufacture the pockels cells in Shalom EO are substantially high, highly deuterated KDP, compared to ordinary KDP crystal, has the merits of effectively reducing the distortion of parasitic oscillation caused by Stimulated Raman Scattering(SRS).

The operation range of  DKDP (KD*P) Pockels cells for Q-switching applications is conventionally 300nm to about 1.1μm, with a high transmission rate above 98%. Virtually most of the low repetition rate DPSS Nd:YAG lasers  and commercial flashlamp-pumped Nd:YAG lasers are equipped with DKDP (KD*P) based Pockels cells for laser cavity Q-switching. Besides, Shalom EO’s DKDP Pockels Cells are also ideal for 694nm ruby aesthetic laser systems, and 755nm Alexandrite Lasers.

Hangzhou Shalom EO offers the DKDP pockels cells with high deuteration (>98%), low capacitance, high transmission rate, and fast rise time during the pulse generation process. Our  capabilities include: maximum aperture up to 50mm, maximum extinction rate >7000:1, highest deuteration rate >99%. Various designs with double-crystal structure, BNC connectors, Liquid Nitrogen encapsulation, integrated polarizers, etc. are available.
