Two Photon Absorption Calculator

Two-photon absorption is a process where an atom or molecule absorbs two photons simultaneously. The energy of two photons can be identical or different. This absorption results in the excitation of the atom or molecule from one energy state to a higher energy state.

Look into the formula for two-photon absorption is,

N=21*δ*ϕ2*τ

where:

• ϕ – Photon flux at the center of a Gaussian beam.
• τ– Exposure time.
• δ – Two-photon absorption

Here are the steps to calculate the two-photon absorption that are given below.

• Firstly, note down all the values that were given in the problem.
• Next, apply the formula, N=21*δ*ϕ2*τ.
• After that, substitute the values and simplify them.
• Finally, you will get the value of two-photon absorption.

1. What is two-photon absorption mean?

Photon absorption is a process in which an atomic electron absorbs the energy of an incident photon.
