DKDP Pockels Cells at 694 or 755 nm

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. FEATURES • Wavefront distortion: <λ/4 • Short rise time: ~3pf • High transmittance: >98% • High damage threshold: >3GW/cm2 • No static birefringence, no photorefractive damage • Anti-reflective coated quartz window • Resistant to ambient temperature shock and excellent electro-optic performance SPECIFICATIONS Parameter Unit Specifications Model Number   CS23238G CS122026G Operating Wavelength nm 694 755 Min.
