Introduction

Calculating laser pulse energy is essential in various scientific and industrial applications. Whether you’re in research, manufacturing, or engineering, having a reliable tool to determine pulse energy accurately is invaluable. In this article, we’ll provide a user-friendly calculator along with the necessary formula and examples to simplify the process.

## How to Use

To use the laser pulse energy calculator, simply input the required parameters into the designated fields and click the “Calculate” button to obtain the result.

## Formula

The formula for calculating laser pulse energy (𝐸*E*) is:

Where:

*P*is the power of the laser in watts (W).*T*is the pulse duration in seconds (s).*A*is the area of the beam in square meters (m²).*R*is the repetition rate in hertz (Hz).

## Example Solve

Let’s say we have a laser with a power (*P*) of 10 watts, a pulse duration (*T*) of 5 nanoseconds, an area (*A*) of 0.001 square meters, and a repetition rate (*R*) of 1000 hertz.

Using the formula:

𝐸=50 nanojoules

So, the laser pulse energy is 50 nanojoules.
