RTP POCKELS CELLS

RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a very desirable crystal material for E-O modulators and Q-switches. It has advantages of higher damage threshold (about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect. As biaxial crystals, RTP’s natural birefringence needs to be compensated by use of two crystal rods specially oriented so that beam passes along the X-direction or Y-direction. Matched pairs (equal lengths polished together) are required for effective compensation.

Advantages

• Wide optical bandwidth (0.5-3μm)

• Low Insertion Loss

• Low half-wave voltage

• High optical damage threshold

• No piezo electric ringing
• Precise switching in high rep rate laser with super-fast voltage drivers
• Thermally compensated design to operate on large temperature range
