Extraordinary second harmonic generation in ReS2 atomic crystals
Yu Song, Siqi Hu, Miao-Ling Lin +3
We report the observations of unexpected layer-dependent, strong, and anisotropic second harmonic generations (SHGs) in atomically thin ReS2. Appreciable (negligible) SHGs are obta…

Microwatts continuous-wave pumped second harmonic generation in few- and mono-layer GaSe
Xuetao Gan, Chenyang Zhao, Siqi Hu +6
We demonstrate the first achievement of continuous-wave (CW) pumped second harmonic generation (SHG) in few- and mono-layer gallium selenide (GaSe) flakes, which are coated on sili…
