How do you calculate peak intensity?

For Gaussian beams, for example, the effective mode area is π w² with the mode radius w, but the peak intensity (i.e., the intensity on the beam axis) is two times the power divided by the effective mode area.

How do you calculate laser intensity?

To calculate the peak power of a laser beam, you would have to divide the energy in each pulse by the duration of the pulse (also known as pulse width). Then, to find the peak power density, you only have to divide the peak power by the area of the beam's cross-section at a given distance.

How do you calculate optical intensity?

At a distance d from a source with radiant intensity I, an area element with its normal direction towards the source receives an irradiance E = I / d².

What is peak fluence?

For a Gaussian beam, the peak fluence is the total optical energy divided by π w² / 2, where w is the Gaussian beam radius. From the time-dependent optical intensity, one can obtain the fluence by temporal integration over the full pulse duration.

What is the intensity of a laser?

The laser intensity is defined as the power per unit area delivered by the incident laser beam [20] and is a critical processing parameter.
