RTP Rubidium Titanium oxide Phosphate crystal is an excellent nonlinear optical crystal, an isomer of potassium titanium phosphate (KTP), with a large nonlinear optical coefficient, and a wide range of near-mid-infrared light transmittance. Due to its excellent characteristics such as high resistivity, low piezoelectric effect, high laser damage resistance threshold and non-easy tidal solution, it is widely used in photoelectric technology fields such as electro-optical modulation and laser Q switching.
Using 1.0 μ M-band laser pumped non critical phase matching cut RTP nonlinear crystals and their isomorphs can achieve efficient 1.5-1.6 μm band eye safe laser, has important applications in the field of nonlinear optical frequency conversion.
