Laser Power Density Calculator

Formula

The formula to calculate the Laser Power Density is:

\[ LPD = \frac{LP}{A} \]

Where:

\(LPD\) is the Laser Power Density (W/m²)
\(LP\) is the total laser power (W)
\(A\) is the total area of the beam (cm²)

What is Laser Power Density?

Laser Power Density is a measure of the intensity of the laser beam, calculated as the power per unit area. It is an important parameter in various applications of lasers, including material processing, medical treatments, and scientific research. Higher power density means more intense laser energy is concentrated in a smaller area.

Example Calculation

Let's assume the following values:

Total Laser Power (LP) = 50 W
Total Area of the Beam (A) = 10 cm²

Using the formula and converting the area to m²:

\[ LPD = \frac{50}{10 / 10000} = \frac{50}{0.001} = 50000 \text{ W/m²} \]

The Laser Power Density (LPD) is 50000 W/m².
