DKDP Pockels Cells
694 or 755 DKDP Pockels Cells
The 694&755 DKDP Pockels Cells are specially designed for unique purposes in medical aesthetic applications. Particularly suitable for 694nm and 755nm wavelengths. 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 wavefront distortion 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 >1GW/cm2 under optical conditions of 10 ns pulse width, 1064 nm wavelength, and repetition frequency of 10 Hz.
