## Laser Pulse Energy Formula

The following equation is used to calculate the Laser Pulse Energy.

PE = LP / f

Variables:

- Where PE is the Laser Pulse Energy (Joules)
- LP is the laser power (watts)
- t is the frequency of the laser (hz)

To calculate a laser pulse energy, divide the laser power by the frequency of the laser.

## How to Calculate Laser Pulse Energy?

The following two example problems outline the steps and information needed in order to calculate the Laser Pulse Energy.

**Example Problem #1:**

- First, determine the laser power (watts). In this example, the laser power (watts) is measured to be 57.
- Next, determine the frequency of the laser (hz). For this problem, the frequency of the laser (hz) is calculated to be 42.
- Finally, calculate the Laser Pulse Energy using the formula above:

PE = LP / f

Inserting the values from above and solving the equation with the imputed values gives:

PE = 57 / 42 = 1.357 (Joules)

**Example Problem #2: **

Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:

laser power (watts) = 95

frequency of the laser (hz) = 4

Entering these values into the formula or calculator above gives us:

**PE = 95 / 4 = 23.75 **(Joules)
