• Low insertion loss
• Low half-wave voltage
• Low operating voltage
• High extinction ratio
• Very high laser damage threshold
• No piezoelectric ringing effect
• Precise switching in high repetitive rate laser with super-fast voltage drivers
• Thermally compensated design for operating in large temperature range
• Compact design, very easy to mount and adjust
• Quality RTP crystal with high environmental resistance and long service life
RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a robust crystal material suitable for a wide range of E-O applications. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect. RTP features good optical transparency from around 400nm to over 4µm and very importantly for intra-cavity laser operation, offers a high resistance to optical damage with power handling ~1GW/cm2 for 1ns pulses at 1064nm.
The E-O Q-switch (Pockels Cells) are based on two RTP crystals in a temperature compensating design
that enables the use of these devices within a wide temperature range from -60 °C up to +70 °C.
RTP Pockels cells are widely used in laser ranging, laser lidar, medical lasers and industrial lasers, etc.
WISOPTIC provides technical consultation, optimized design, customized test sample, and fast-delivery standard products of RTP Pockels cells for high repetition rate Q-switching & pulse-picking.
