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.
Beam Profiling for Small Beam Widths or Spot Size

Beam width or spot size is an important parameter to identify in selecting the optimal beam profiler. Scanning slit beam profilers are ideal for measuring small Gaussian beams.
