## Laser Power Density Formula

The following formula is used to calculate the Laser Power Density.

LPD = LP / A

- Where LPD is the Laser Power Density (W/m^2)
- LP is the total laser power (W)
- A is the total area of the beam (cm^2)

To calculate the laser power density, divide the laser power by the area of the beam.

## How to Calculate Laser Power Density?

The following example problems outline how to calculate Laser Power Density.

Example Problem #1:

- First, determine the total laser power (W).
- The total laser power (W) is given as: 50.

- Next, determine the total area of the beam (cm^2).
- The total area of the beam (cm^2) is provided as: 10.

- Finally, calculate the Laser Power Density using the equation above:

LPD = LP / A

The values given above are inserted into the equation below:

LPD = 50 / 10 = 5 (W/m^2)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total laser power (W) = 502

total area of the beam (cm^2) = 250

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

LPD = LP / A** = ?**
