Did you know?
WebLaser Micro Line or Micro Focus Generators are designed to produce lines with small line width or spots with small spot diameters. They have a small depth of focus (in this case the depth of focus is the Rayleigh range). They have a high power density in the focus and a Gaussian intensity profile across the laser line/spot. WebMay 4, 2024 · The ratio of the two values, M 2 (M-squared), is often specified for laser beams. Multiply the beam's Rayleigh range by the M 2 value, and then use this product as …
