DKDP (KD2PO4) Pockels Cells, also known as potassium deuterium phosphate pockels cells or DKDP pockels cells. It is a pockels cells device with excellent overall performance.

DKDP crystals have a low optical loss, high extinction ratio, good electro-optical properties, and good tolerance to the environment, etc. They can be used in these fields:

  • Electro-optical Q-switches
  • High-speed camera switches
  • Military, and aviation laser systems
  • Dye lasers 800 nm two- and three-fold
  • 1064 nm two-, three- and four-fold fields

Ambient temperature range: 10~50 degrees, temperature change should not exceed 5 degrees every 20 minutes, ambient humidity: <40%. Try to use a humidity control device (desiccant and desiccator). When not in use, please store it in a dry box.

Features of DKDP Pockels Cells:

  • Non-Static Birefringence
  • No light refraction damage
  • High resistance to photodamage threshold
  • Excellent electro-optical coefficient
  • Good tolerance to environment
  • Good airtightness and no adhesive
  • DKDP crystals with high deuterium content

Standard
