What is ISO 11452-13: 2018 ?

Title: Understanding EN ISO 11452-13: 2018: A Technical Standard for Measuring Laser Beam Geometrical Characteristics

The world of laser technology is constantly evolving, and with it, the need for high-quality standards to ensure the efficiency and accuracy of laser systems. One such standard is EN ISO 11452-13: 2018, a technical guideline that provides guidelines for measuring the geometrical characteristics of laser beams. This standard is part of the ISO 13146 series, which covers laser beam characterization across various aspects.

Purpose of EN ISO 11452-13: 2018:

The purpose of EN ISO 11452-13: 2018 is to establish a set of criteria for measuring the M-squared value of a laser beam, which is an important parameter for characterizing its quality. The M-squared value assesses the ratio between the real beam divergence and the divergence of an ideal Gaussian beam with the same beam width. By measuring this ratio, one can evaluate the quality and efficiency of a laser system, ensuring that it meets specific requirements for various applications.

Key Measurements and Parameters:

EN ISO 11452-13: 2018 provides guidance on the key measurements and parameters that should be used to measure the M-squared value of a laser beam. These measurements and parameters include:

Beamwidth: The width of the laser beam, which is the distance between the center of the beam and the edge.

Convergence: The degree to which the beam converges, which is measured by the beam's angle of divergence.

Divergence: The degree to which the beam spreads out, which is measured by the beam's angle of spread.

Efficiency: The ratio between the real beam divergence and the ideal Gaussian beam divergence, which is used to assess the quality of the laser system.

EN ISO 11452-13: 2018 also provides guidance on the equipment and methods used to measure these parameters, as well as the interpretation of the results.

Conclusion:

EN ISO 11452-13: 2018 is an important standard for anyone involved in the development, production, or use of laser systems. By following the guidelines outlined in this standard, one can ensure that their laser systems are of high quality, reliable, and meet specific requirements for various applications.
