How to Calculate Laser Beam Size - Laser Measurement Blog- laser beam waist calculator ,1/e2.. This is probably the most commonly used in research circles.. By the 1/e 2 method, you measure beam width between the two points where the intensity is 1/e 2 of the peak value.. Clear definition, but only about 86% of the laser power is contained within the 1/e 2 width.. (Our new “power through aperture” calculator lets you easily see ..Laser beam spot size calculator | LasercalculatorWith these inputs, the diameter of the focal spot is.. 2 w 0 = 4 M 2 λ f π D.. 2w_0 = \dfrac {4 M^2 \lambda f} {\pi D} 2w0.. .. = πD4M 2λf.. .. To get this diffraction-limited beam diameter, the lens should not have strong aberrations.. Additionally, the lens diameter should be at least twice the beam diameter input value not to clip the "wings ..

The beam waist (or beam focus) of a laser beam is the location along the propagation direction where the beam radius has a minimum.. The waist radius is the beam radius at that location.. Figure 1: The beam waist is the location where the beam radius is smallest.. A small beam waist (more precisely, a beam waist with small waist radius), also ..
The function w ( z) is the beam radius as a function of location z along the axis.. As seen above, when z = z 0 it reaches a minimum value w 0, called the beam waist.. For a Gaussian beam propagating in free space, the beam radius at any point only depends on the waist w 0, its location z 0, and the wavelength.. w ( z) = w 0 1 + ( z − z 0 z R) 2..

The beam waist size is not one of the input parameters that you can specify when using the thin lens method, so to generate a beam with a given beam waist radius, you can set the distance from focus property to 0 to calculate the field profile at the focal plane, and vary the numerical aperture until the calculated beam has the desired waist ..
Beam diameter = 0..48 mm.. Measured divergence = 1..7 mrad.. Knowing the wavelength and the far field divergence angle, the beam waist is calculated to be 0..118 mm, with a Rayleigh range of 69..7 mm.. We will model this system using Paraxial Gaussian beam analysis tool so that the beam spot is the smallest at 30 mm away from the laser output..

Result.. Rayleigh Length (or Rayleigh Range) m.. Rayleigh Range (ZR) is the distance from the beam waist where the beam radius has increased 1..414 times its initial value.. This is the point at which the area of cross-section is doubled.. If we focus a laser beam, at the focal point, theoretically the intensity goes to infinity..
spot_size = 1,22 * lambda / NAeff.. to get spot size smaller than lambda, you need NAeff larger than 1,22, which is rather high and unlikely.. Further you may either use other factors instead of 1 ..
Note: Results greater than 1,000,000 are rounded to infinity.. Description.. Mathematically model beam propagation of Gaussian beam using simple geometric parameters.. Calculator uses first order approximations and assumes TEM 00 mode to determine beam spot size in free space applications.. Please note that results will vary based on beam quality and application conditions..

The beam diameter is defined as the distance between the points opposite to the diameter of the beam diameter surface, where the power per unit area of the beam is 1/e (0..368) times the displacement power per unit area.. This is the definition of the beam diameter and is used to calculate the maximum allowable exposure of the laser beam..

When a laser beam propagates along its optical path, its diameter is continually changing.. If we consider the ideal case of a Gaussian beam, the beam width (or radius, w) along the propagation axis z is defined by the following equation: where w 0 is the beam waist (the smallest radius of the Gaussian beam) and z R is the Rayleigh length:
