Welcome to the BeamSpread Calculator, a useful tool for calculating the spread of a laser beam as it propagates.
The calculator will perform a laser beam divergence calculation using the entered parameters and display the results.
For engineers, laser technicians, and physicists, understanding the divergence of laser light during propagation is essential.
Note: When using this calculator, please provide the accurate laser wavelength, cross-sectional diameter, and propagation distance, and make sure the units used are consistent with the units expected by the calculator for accurate calculations.
