Construction and analysis of statistical models for laser power density in bucket

The power density in bucket is a critical indicator for characterizing laser capabilities, its statistical model serves as an essential tool for analyzing and evaluating laser parameters. This study conducted comparative analysis of the distribution morphology of the power density in bucket under different sampling methods, focusing on investigating the influence of sampling strategies on the distribution, summmaring the key characteristics of the distribution. To address the challenge of model establishment caused by an excessively small scintillation index, a new data processing method is proposed. This method effectively extends the applicability of statistical models and increases the diversity of selectable model types; Multiple statistical models are established under different sampling approaches, followed by comparative analysis.This research provide foundational support for the establishment and evaluation of statistical model establishment of power density in bucket.
