# Abstract
 
This project presents a comprehensive implementation scheme for a high-precision laser beam quality analyzer designed to measure and analyze critical laser beam parameters including M² factor, beam diameter, divergence angle, beam profile, ellipticity, and pointing stability. The system employs multiple measurement methodologies (knife-edge scanning, moving slit scanning, and camera imaging) to ensure accurate and reliable beam characterization across a wide wavelength range (400nm-2000nm) and power range (1μW-10W). The hardware architecture integrates precision optical components, high-resolution detectors, micro-positioning stages with 0.1μm accuracy, and advanced data acquisition systems, while the software platform provides real-time data processing, automated measurement workflows, and comprehensive reporting capabilities. With measurement precision of ±5% for M² factor and ±2% for beam diameter, this analyzer is suitable for applications in laser processing, laser communications, scientific research, and quality control, offering a robust solution for laser beam characterization and optimization in various industrial and research environments.
