Non-invasive fluorescence retinal imaging in small animals is an important requirement for an array of translational vision applications.The in vivotwo-photon i
Spatial modes have received substantial attention over the last decades and are used in optical communication applications.In fiber-optic communications,the emp
We demonstrate the first achievement of continuous-wave (CW) pumped second harmonic generation (SHG) in few-and monolayer gallium selenide (GaSe) flakes,which a
