Results:

What is Gaussian beam propagation?

Gaussian beam propagation refers to the way a laser beam spreads as it moves through space.

How is beam waist calculated?

The beam waist is determined by the initial conditions of the laser source.

What is the Rayleigh range?

The Rayleigh range is the distance over which a beam maintains its focus.

What affects beam divergence?

Beam divergence is affected by the wavelength and beam waist.

Can this calculator be used for fiber optics?

Yes, it is useful for fiber optic calculations.

What is diffraction in optics?

Diffraction is the bending of light around obstacles.

What is a laser spot size?

The spot size is the diameter of the focused beam.

How do I minimize beam divergence?

Using a lens or a collimator can minimize divergence.

Why is Gaussian beam important?

Gaussian beams are widely used in optics due to their stable properties.

Can I use this for medical lasers?

Yes, it can be useful for medical laser applications.
