RTP (Rubidium Titanyle Phosphate – RbTiOPO4) is a material now widely used for Electro Optical applications whenever low switching voltages are required.
RTP (Rubidium Titanyle Phosphate – RbTiOPO4) is an isomorph of KTP crystal which is used in nonlinear and Electro Optical applications. It has advantages of higher damage threshold (about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopic and no piezo-electric effect. It 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. Its transmission range is 350nm to 4500nm.
Advantages of RTP:
It is an excellent crystal for Electro Optical applications at high repetition rate
Large nonlinear optical and electro-optical coefficients
