Abstract

The setting of sampling points on the detector array will affect the fitting error of Gaussian beam. Based on MATLAB and least square method, the fitting of ideal Gaussian beam in one dimension and two dimensions was simulated, and the influence of sampling point interval on the fitting error of characteristic parameters, such as facula center, facula radius and center power density, were studied. The results show that, the number of sampling points in the two-dimensional simulation is greater, so the fitting accuracy is better than that in the one-dimensional simulation under the same condition of sampling point interval. In the range of initial conditions of simulation calculation, the interval of sampling points shall be d≤50mm, then the fitting error would be controlled within the range of admissible one.
