Large Aperture DKDP Pockels Cells

Crystrong’s Large Aperture DKDP Pockels Cells are specially designed for high power, high energy, large spot applications. The DKDP crystal is a uniaxial crystal with excellent optical quality with an extinction ratio of >2000:1 (measured using a 632 nm He-Ne laser) with a transmittance of 98%. The DKDP electro-optic Q- switching capacitor is small (about 3-5pF), so the rise time is short (<0.5ns), and a narrow pulse width pulse laser can be output during Q-switching. Compared with the widely used electro-optic crystals on the market, DKDP crystals have higher damage thresholds; the damage threshold is >3GW/cm² under optical conditions of 10 ns pulse width, 1064 nm wavelength and repetition frequency 10 Hz.
