Aperture optional (>10mm) nitrogen encapsulated DKDP Pockels Cells, Code: 2031-023

This one module of DKDP Pockels cells is capsulated with Liquid Nitrogen to prevent overheating,  and the quality of the crystal is outstanding with no stress stria and growing stria. This module also features a decent extinction ratio(>5000:1) and a high damage threshold(>1GW/cm2).

Hangzhou Shalom EO offers a series of DKDP Pockels Cells with high deuteration (>98%), fast rise time, and high optical transmission. Our capabilities include a maximum extinction ratio (>7000:1), and the largest aperture of 50mm. Various designs with double-crystal structure, BNC connectors, Liquid Nitrogen encapsulation, integrated polarizers, etc. are available

Application Notes:

With excellent physical and optical property, DKDP series Pockels cells are widely used in laser systems with large caliber, high power and narrow pulse width. They are among the optimal E-O Q-switches used in pulse laser systems, including:

  1. OEM laser systems
  2. Medical/cosmetic lasers
  3. Versatile R&D laser platforms
  4. Military & aerospace laser systems

Application Notices on DKDP Series Q-switch:

  • Core exposure or loose contact is forbidden
  • Recommend to be operated at constant temperature
  • Pease avoid any intense impact or vibration
  • Unauthorized disassembly is forbidden
