Frequently Asked Questions

What is this.

Non-Diffractive Beams (NDB) - What is non diffractive beam?

A non-diffractive beam was first proposed by Durnin et al. in 1978 as a light beam having a transverse intensity distribution that can be modeled using a Bessel function. The beam profile remains unchanged even if it propagates over a long distance.

What is your value proposition?

Low-cost
Extremely compact spot size and very low divergence
Non-diffractive over long distances
Self-constructive after obstacles
Robust to jitter, vibrations, and variations on the angle of the input beam

What is a bessel beam?

A Bessel beam is a focus high intensity beam a at the centre. There is central spot where all the energy is concentrated. The intensity distribution is not uniform or controllable.

So, why is this called the Structured Laser Beam?

The characters of the CERN technology is very similar to the Bessel Beam. However, the uniqueness is that the rings around the central spot can be controlled and tuned. The size of the central beam, the divergence of the full beam and the distribution of the rings - all of them adjustable based on applications.

Does the laser reconstrruct?

The SLB self reconstructs when the path is an obstacle. This has many applications where the laser has to travel where there are either known obstacles or unknown ones. For example, in medical applications (where there might be a known obstacle) or in telecommunications – free space optics where there might be unknown obstacles.
