Small Beam Width Theoretical and Experimental Error

Beam Profiling Concepts |March 14, 2016

One of the most important measurements in laser beam profiling is the beam width measurement. A common question we see is “How small of a beam can I measure with this camera?”

Systematic Error in ISO 11146 Measurements

Beam Profiling Concepts |May 12, 2016

Systematic error is an important calculation in any measurement system, and especially in ISO 11146 laser beam profiling measurements. In this blog post, we address the systematic error inherent to the measurement of beam width as laid out in the ISO 11146 standard.

Flat-Top Beams and Plateau Uniformity Calculations

Beam Profiling Concepts |February 26, 2016

A flat-top beam (otherwise known as a top-hat) is used in various applications where a controlled profile is desired (i.e. a uniform density across the irradiated surface). Passing a Gaussian beam through special optics will create the flat-top beam and is the most common way of generating a flat-top beam. Uniform excimer beams are used in many material processing applications (e.g. creating integrated circuits). Industries such as welding, drilling, and medicine also make extensive use of flat-top beams.
