Abstract

We report on the nonlinear optical properties of few-layer GaTe studied by multiphoton microscopy. Second and third harmonic generation from few-layer GaTe flakes were observed in this study with the laser pump wavelength of 1560 nm. These processes were found to be sensitive to the number of GaTe layers. The second- and third-order nonlinear susceptibilities of 2.7 × 10^-9 esu (1.15 pm/V) and 1.4 × 10^-8 esu (2 × 10^-16 m²/V²) were estimated, respectively.
