KTP crystal features a large nonlinear coefficient, low temperature sensitivity, good mechanical properties, and is non-hygroscopic. It is widely recognized as one of the best-performing nonlinear optical crystals and is the preferred material for low to medium power frequency doubling and optical parametric oscillation. It finds extensive applications in green lasers, medical devices, and optical communications.
