DKDP Pockels Cells at 694 or 755 nm

Request a Quote

DKDP Pockels Cells possess 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).

DKDP Pockels Cells

DKDP electro-optic Q-switches (Q-switch, Pockels Cells) are widely used in large-caliber, high-power, narrow-pulse (<10 ns) laser systems due to their unique physical properties and excellent optical quality.

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- 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.
