# Gaussian Beam Intensity Calculator Online

A Gaussian beam is a type of electromagnetic radiation, typically light, whose intensity distribution near its source can be approximated by a Gaussian function. The Gaussian beam is named after the mathematical function because its mathematical description involves the Gaussian distribution. The beam’s intensity describes how the power is distributed across the beam’s cross-sectional area. It’s a critical parameter in optics, often measured in Watts per square millimeter (W/mm²).

Understanding the Gaussian Beam Intensity Calculator, therefore, is essential for anyone involved in optics. This tool calculates the Gaussian beam intensity given the total beam power and the beam waist radius.

## Working of the Gaussian Beam Intensity Calculator

The calculator works based on the Gaussian Beam Intensity formula. It calculates the beam’s intensity in a straightforward and efficient manner, allowing the user to predict the intensity distribution of a Gaussian beam. Given the total beam power (P) and the beam waist radius (w), the calculator gives an accurate reading of the Gaussian beam intensity (I).

## Gaussian Beam Intensity Formula and Variables

The Gaussian Beam Intensity formula is as follows:

I=2∗P/(π∗w²)

Where:

• I: Gaussian Beam Intensity (measured in W/mm²)
• P: Total beam power (measured in Watts)
• w: Beam waist radius (measured in mm)

## Detailed Example

Let’s work through an example to better understand the calculator’s use:

Given:

• Beam Power (P): 22 W
• Beam Waist Radius (w): 33 mm

Using the formula, we can calculate the Gaussian Beam Intensity (I) as follows:

I = 222/(π(33)²) = 0.012861016365611174 W/mm²

Thus, the Gaussian Beam Intensity is approximately 0.01286 W/mm².

## Applications of Gaussian Beam Intensity Calculator
