Fig. 3From: Diffraction of a Gaussian beam near the beam waistThe experimentally obtained diffraction patterns in the far field at the different distance from the focal plane: a) the screen is located at the distance of 1.5 mm before the focal plane, b) the screen is located at the distance of 75 μm before the focal plane, c) the screen is located in the focal plane, d) the screen is located at the distance 75 μm after the focal plane, e) the screen is located at the distance of 1.5 mm after the focal planeBack to article page
