High Power Lasers – Just Measure It
Laser power and the applied laser densities are constantly rising. These high-power lasers are more likely to be used in materials processing applications such as welding, cutting, cladding, or additive manufacturing. Many of those applications are demanding: The laser’s focal spot and beam profile need to be kept within the specification to achieve the required…
