…why two beams of identical power and
diameter (or contour) leave different burn marks on a substrate if one beam features a Gaussian profile (maximum
intensity in the beam center) while the other beam features a so-called donut profile (very little to no power in the
beam center).…

the beam profilers dedicated to UV, visible, or NIR, respectively. Another proprietary approach based on converting IR beams
into visible radiation is used for applications in the IR."

…stability, the excellent beam profile, the high conversion efficiency and the option of
tunable operation, are all similar to the 700-980 nm version. The typical achievable pulse
duration is < 50 fs.

…metals. Plus, their large area output "beam" can be easily reshaped to produce a wide range of line profiles, well matched for high-throughput, powder or wire-fed cladding applications (Figure 1). For example, a Coherent HighLight diode laser system can deliver beams up to 12 mm wide and up to 36 mm…
