WebbThe near field of a laser beam is a region at or very close to the output aperture that is characterized by disordered phase fronts and often called the Fresnel zone. In the near field, beam shape, size, profile and divergence can vary rapidly with distance. How far the near field extends depends greatly on laser type. Webb31 mars 2024 · The beam has traveled a long optical distance, from focus to the front of the first lens, which is essentially a Fourier transform of the beam. In Fourier transforms, the resolution at a surface is inversely proportional to the grid width at the previous surface. one night show 2022

WebbArrays allow the entire beam to impact the detector, leading to detector saturation unless the beam is severely attenuated. Lasers of any wavelength with powers above 100mW can be measured with the pyroelectric detector equipped scanning slit profiler. Properly designed, these profilers can measure up to kilowatts of laser power. WebbSpatial beam profiling is the one measurement that combines all the variables that create a laser beam into one intuitively easy to understand visual image.
