What Does PPKTP Stand For?

PPKTP stands for Periodically Poled KTiOPO4

PPKTP, or Periodically Poled KTiOPO4, is a nonlinear optical crystal known for its efficient frequency conversion properties. It is fabricated with a periodic domain structure that enables quasi-phase matching, resulting in enhanced performance in applications such as second-harmonic generation and optical parametric oscillation. PPKTP is widely used in various photonics applications, including laser systems, telecommunications, and sensing technologies, due to its favorable wavelength range and temperature stability.
