This formula uses 1 Constants, 5 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Laser Energy Output - (Measured in Watt) - Laser Energy Output refers to the amount of energy emitted by a laser over a specific period of time.
Power Density of Laser Beam - (Measured in Watt per Square Meter) - Power Density of Laser Beam is the power per unit area of beam.
Focal Length of Lens - (Measured in Meter) - Focal Length of Lens is determined when lens is focused at infinity. Lens focal length tells us angle of view and how much of scene will be captured. The longer focal length, a narrower angle of view.
Beam Divergence - (Measured in Radian) - Beam Divergence is the angle made by the beam incident on surface of metal.
Laser Beam Duration - (Measured in Second) - Laser Beam Duration is the time for which laser beam is incident on the work surface.
STEP 1: Convert Input(s) to Base Unit
Power Density of Laser Beam: 9.49 Watt per Square Centimeter --> 94900 Watt per Square Meter (Check conversion ​here)
Focal Length of Lens: 3 Meter --> 3 Meter No Conversion Required
Beam Divergence: 0.001232 Radian --> 0.001232 Radian No Conversion Required
Laser Beam Duration: 10.2 Second --> 10.2 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P = (δp*pi*flens^2*α^2*ΔT)/4 --> (94900*pi*3^2*0.001232^2*10.2)/4
Evaluating ... ...
P = 10.3853273599277
STEP 3: Convert Result to Output's Unit
10.3853273599277 Watt --> No Conversion Required
FINAL ANSWER
10.3853273599277 10.38533 Watt <-- Laser Energy Output

How does Laser Beam Machining work ?

Laser (light amplification by stimulated emission of radiation) beam machining (LBM) utilises the energy from the coherent light beams called laser (light amplification by stimulated emission of radiation). The basic principle utilised in LBM is that under proper conditions light energy of a particular frequency is used to stimulate the electrons in an atom to emit additional light with exactly the same characteristics of the original light source.

How to Calculate Laser Energy Output?

Laser Energy Output calculator uses Laser Energy Output = (Power Density of Laser Beam*pi*Focal Length of Lens^2*Beam Divergence^2*Laser Beam Duration)/4 to calculate the Laser Energy Output, The Laser Energy Output formula is defined as the output power of the laser beam used in LBM. It is used to calculate power density of laser beam. Laser Energy Output is denoted by P symbol.
