With the increase in high output such as fiber lasers, the necessity to measure beam quality (M2) and profiles is becoming increasingly important. Haas Laser Technologies offers a wide range of beam analyzer systems that can be used inline and in real-time, suitable for both low and high output levels. In this seminar, we will provide detailed explanations about the principles, usage, and product lineup. Contents: (1) Principles and configuration for achieving real-time M2 measurement (2) Basic usage of the products and software operability (3) ISO-compliant measurement methods and specific examples (4) Product lineup (single camera, dual camera, etc.) (5) Future product developments
