RTP (RbTiOPO4) is an isomorph of KTP crystal. RTP single crystals are grown in WISOPTIC by a slow-cooling flux method. RTP has many advantages e.g. large nonlinear optical coefficient, large E-O coefficient, high damage threshold (about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopy and no induced piezo-electric effect with electrical signals up to 60 kHz. The transmission range of RTP is 350 nm to 4500 nm.
Applications of RTP Crystal:
• Second harmonic generator (SHG) of radiation 1.064 µm
• Optical parametric oscilator (OPO) in near IR region up to 4 µm
• Different frequency generator in near IR region
