Diameter of Spot Produced by Laser Solution

STEP 0: Pre-Calculation Summary

Formula Used

Spot Diameter = Focal Length of Lens*Beam Divergence
d_spot = f_lens*α
This formula uses 3 Variables

Variables Used

Spot Diameter - (Measured in Meter) - Spot Diameter refers to the width of the laser beam at its focal point or the point where it strikes a surface.
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

d_spot = f_lens*α --> 3*0.001232

Evaluating ... ...

d_spot = 0.003696

STEP 3: Convert Result to Output's Unit

0.003696 Meter --> No Conversion Required

FINAL ANSWER

0.003696 Meter <-- Spot Diameter

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.
