Alok Kumar Pandey was the lead author in our recently published paper “Shack-Hartmann Wavefront Sensing of Ultrashort Optical Vortices”. Based upon his work at LASERIX laboratory of the University of Paris-Saclay, in collaboration with Imagine Optic and co-author Guillaume Dovillaire, this publication details the complete characterization of beams hosting various orbital momenta. 

Light beams hosting Orbital Angular Momentum (OAM), also known as optical vortices (OV), have led to fascinating new developments in fields ranging from quantum communication to novel light–matter interaction aspects. The characterization was easily and precisely established using a HASO4 FIRST wavefront sensor in the infrared bandwidth and Waveview wavefront sensing metrology software.
