The influence of smoothing by spectral dispersion on the beam characteristics in the near field

doi:10.1088/1674-1056/22/10/104210

Abstract The influences of SSD on the beam characteristics in the near field are investigated. Results show that if the SSD parameters are increased, the laser intensity modulation increases while fluence modulation decreases, which is attributed to the temporal and spatial variation of the SSD pulse phase. The variations of intensity and fluence modulations with the SSD parameters are given. The simulation results are presented along with a method for choosing appropriate SSD parameters according to the variations and the requirements of applications.

Keywords: smoothing by spectral dispersion intensity modulation degree fluence modulation degree
