KTP is most commonly used for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly in low to medium power density regimes, and is suitable for both intra-cavity and extra-cavity configurations. In addition to SHG, KTP can also be employed as a nonlinear medium in optical parametric oscillators (OPOs) for infrared generation up to approximately 4 µm, including use as a pump source for mid-IR OPO systems based on crystals such as ZGP.
