Calculate your laser's fiber numerical aperture or maximum incident angle. Use Gentec-EO's online laser calculators to quickly calculate or convert common laser beam parameters.
Calculate the size and location of your Gaussian laser beam waist at focus, as well as the Rayleigh range. Laser Focusability Calculator. Quantify laser diffraction-limited focal spot size, assuming an ideal lens without aberrations and a collimated laser beam. Temperature Rise Calculator.
As mentioned, this calculator is meant for parameters around the waist, and not suited for far-field applications. It also assumes that you have a perfect TEM 00 Gaussian Beam, and that the emission spectrum of the laser is infinitesimally small and could be described as a single wavelength. It’s also assumed that the laser beam is going through a homogenous isotropic continuous medium in ...
This calculator gives you the laser spot size and laser beam waist values based on the beam diameter at lens, wavelength, and other parameters you input.
