The Sun has captivated humanity for millennia. And yet, despite being our closest star, studying it is not easy. Its blinding ...

Abstract: We proposed a slanted grating suitable for RGB bands which is polarization-independent and has a high diffraction efficiency of -1st order under normal incidence. We used Rigorous Coupled ...

Abstract: This paper presents a near-infrared (NIR) laser scanner developed using a microelectromechanical system (MEMS). The scanner leverages the transmitted diffraction beam of an in-plane ...

Ultrashort laser pulses - that are shorter than a millionth of a millionth of a second -have transformed fundamental science, engineering and ...
