Influence of spatiotemporal coherence of broadband laser on beam smoothing of ISI

Beam Shaping by Mode Superposition With Coefficient Optimization

“…I. INTRODUCTION eneration of beams with specific intensity distribution is a fundamental prerequisite for applications ranging from the interaction between laser and matter [1][2] to particle manipulation [3][4] and laser fusion [5][6]. Chen et al demonstrated that, with suitable ratio of particle diameter to wavelength, the flat-top focus exhibits the largest trapping efficiency in comparison with a Gaussian beam and a donut shaped beam [3].…”
