Efficient Second- and Third-Harmonic Generations in Er<sup>3+</sup>/Fe<sup>2+</sup>-Doped Lithium Niobate Single Crystal with Engineered Surficial Cylindrical Hole Arrays

Efficient Second- and Third-Harmonic Generations in Er<sup>3+</sup>/Fe<sup>2+</sup>-Doped Lithium Niobate Single Crystal with Engineered Surficial Cylindrical Hole Arrays

Herein, significant enhancement of second- and third-harmonic generation efficiencies in a 1 mol% Er<sup>3+</sup> and 0.07 mol% Fe<sup>2+</sup>-doped lithium niobate single-crystal plate were achieved after ablating periodic cylindrical pit arrays on the surface. Enhanced abs...
