The PCK6-800/PCR6-800 from EKSMA Optics is a Potassium Titanyl Phosphate (KTP)/Rubidium Titanyle Phosphate (RTP) Pockels Cell that operates at a wavelength of 800 nm. It has an optical transmission above 98% and clear aperture of 5.5 mm. This pockels cell has a half wave voltage of less than 2.1 kV and minimum capacitance of 6 pF. It has a contrast ratio of greater than 1:5000 and 2 crystals with a crystal size of 10 (L) mm x 6 (W) mm x 6 (H) mm. This pockels cell has standard aperture sizes of 4 mm x 4 mm & 6 mm x 6 mm with high duty cycles and low piezo-electric resonances. It is available in a thermally compensated double-crystal configuration that measures Ø 25.4 mm x 42.2 mm and is ideal for pulse picking & Q-switching for high repetition rate lasers (1 kHz - 6 MHz).
