Gaussian beams are particular modes of propagation of a light beam with a characteristic minimum spot size (waist): with our beam spot size calculator, you will learn how a lens intercepting a collimated Gaussian beam can focus it to a small beam spot size.

In optics, the length at which the beam still maintains a high degree of coherence and focusing is the depth of focus. We define it as two times the Rayleigh range:

The size of the beam spot is fundamental if you want to calculate the intensity of a pulsed laser, since it equals the ratio between the power of the pulse and the beam area: find out more at our laser pulse calculator.

The value of the depth of focus is important in the planning of an experimental set-up since it defines the distance at which it's "safe" to place an optical element.

The spot size can't be reduced arbitrarily. The wavelength of the light and the focal length of the lens defines the beam spot at the diffraction limit. To calculate this value, substitute M2M^2M2 with the ideal value 111 in the equation above.

After reaching its minimum spot size, a Gaussian beam retains its properties for a certain length, after which the divergence (a measure of how much the beam "opens") takes over. Coherence, both temporal and spatial, is lost, and the light resembles more and more a "normal" beam.

We will assume we are lighting a lens with focal length fff with a collimated Gaussian beam with a diameter at the lens ddd.

Scientists often use lasers for materials characterization in their studies. The Sellmeier dispersion formula is one of the methods that need the light of a specific wavelength, and we have a tool dedicated to that topic!

Interestingly, the laser brightness doesn't affect the beam spot size, even though at higher powers it's likely that the beam will deviate from ideality.

The nature of the Gaussian beam causes it to focus not in a point but in a spot: the lens modifies (compresses) the beam, which, however, retains all its features.
