Enter the polarized electric field amplitude and the laser carrier frequency into the Ponderomotive Energy Calculator. The calculator will evaluate the Ponderomotive Energy.

## Ponderomotive Energy Formula

The following two example problems outline the steps and information needed to calculate the Ponderomotive Energy.

Up = Ea^2/ (4*w^2)

Variables:

- Up is the Ponderomotive Energy (atomic units of energy)
- Ea is the polarized electric field amplitude
- w is the laser carrier frequency

## How to Calculate Ponderomotive Energy?

The following steps outline how to calculate the Ponderomotive Energy.

- First, determine the polarized electric field amplitude.
- Next, determine the laser carrier frequency.
- Next, gather the formula from above = Up = Ea^2/ (4*w^2).
- Finally, calculate the Ponderomotive Energy.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

polarized electric field amplitude = 234

laser carrier frequency = 104

Up = Ea^2/ (4*w^2)** **= ?
