DKDP Pockels Cells

Description: 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 of 10 Hz.

Application: 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. 

Features:

 Short rise time: ~3pf 
 High transmittance: >98% 
 Transmission Range: 200~3100nm 
 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
