Diameter of Spot Produced by Laser Solution

STEP 0: Pre-Calculation Summary
Formula Used
Spot Diameter = Focal Length of Lens*Beam Divergence
dspot = flens*α
This formula uses 3 Variables
Variables Used
Spot Diameter - (Measured in Meter) - Spot Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
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.
STEP 1: Convert Input(s) to Base Unit
Focal Length of Lens: 3 Meter --> 3 Meter No Conversion Required
Beam Divergence: 0.001232 Radian --> 0.001232 Radian No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
dspot = flens*α --> 3*0.001232
Evaluating ... ...
dspot = 0.003696
STEP 3: Convert Result to Output's Unit
0.003696 Meter --> No Conversion Required
FINAL ANSWER
0.003696 Meter <-- Spot Diameter
(Calculation completed in 00.004 seconds)

8 Power density of laser beam Calculators

Focal Length of Lens
Go Focal Length of Lens = sqrt((4*Laser Energy Output)/(pi* Power Density of Laser Beam*Beam Divergence^2*Laser Beam Duration))
Beam Divergence
Go Beam Divergence = sqrt((4*Laser Energy Output)/(pi*Focal Length of Lens^2*Power Density of Laser Beam*Laser Beam Duration))
Power Density of Laser Beam
Go Power Density of Laser Beam = (4*Laser Energy Output)/(pi*Focal Length of Lens^2*Beam Divergence^2*Laser Beam Duration)
Pulse Duration of Laser
Go Laser Beam Duration = (4*Laser Energy Output)/(pi*Focal Length of Lens^2*Beam Divergence^2*Power Density of Laser Beam)
Laser Energy Output
Go Laser Energy Output = (Power Density of Laser Beam*pi*Focal Length of Lens^2*Beam Divergence^2*Laser Beam Duration)/4
Beam Divergence given Diameter of Spot
Go Beam Divergence = Spot Diameter/Focal Length of Lens
Focal Length given Diameter of Spot
Go Focal Length of Lens = Spot Diameter/Beam Divergence
Diameter of Spot Produced by Laser
Go Spot Diameter = Focal Length of Lens*Beam Divergence

Diameter of Spot Produced by Laser Formula

Spot Diameter = Focal Length of Lens*Beam Divergence
dspot = flens*α

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.
