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)


  • 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.

  1. First, determine the polarized electric field amplitude. 
  2. Next, determine the laser carrier frequency. 
  3. Next, gather the formula from above = Up = Ea^2/ (4*w^2).
  4. Finally, calculate the Ponderomotive Energy.
  5. 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) = ?
