One of the acceleration beams of the LFEX laser in Osaka. The divergence angle of a Gaussian beam is determined by Equation 2: The resulting divergence angle can be inserted into Equation 2 to simplify the calculation of the M2 factor of a Gaussian beam: An M2 factor of 1 corresponds to a diffraction-limited Gaussian beam, and M2 factors larger than 1 correspond to a beam that deviates from the ideal Gaussian beam. This includes compact laser beam profilers and more complex instruments for measuring M2 beam quality factor by automatically analyzing the beam propagation. A full characterization of a monochromatic laser beam could in principle lead to the complete complex amplitude profile in one plane perpendicular to the beam, from which the further evolution (propagation) of the beam could be calculated with a suitable beam propagation software, for example. Laser processing applications that leverage laser scan heads are especially susceptible to errors from thermal loads. Moreover, his channel was suitable to be called as the Australian version of that channel as the content was almost identical. Figure 2 shows why multiple radius measurements at different planes are needed to calculate M2. Power in the bucket (PIB) is another parameter used for describing beam propagation and quality, and is commonly used in materials-processing and other high-power laser applications, as PIB has a direct bearing on the ability to form a small and intense spot on an object or a material being processed.
