Analysis on FM-to-AM conversion of SSD beam induced by etalon effect in a high-power laser system
Fig. 1. Schematic representation of the beam mixing process in transmission plate.
Fig. 2. Samples of equivalent phases and the corresponding AM patterns of SSD beam induced by etalon effect. In the left three figures, red curves and blue curves denote the equivalent phase and the original phase, respectively. The parameters are (a) one sinusoidal phase modulation with
Fig. 3. Schematic representations of the focusing process for an SSD beam (single sinusoidal phase modulation). Integration of intensity on focal plane can reduce the distortion criterion of SSD beam. The colors represent the isointensity surface in near field, and the horizontal dashed line corresponds to AM patterns in near field as shown in Figure
