Beam Attenuation: A Key to Successful Beam Profiling
Sensors used in most beam profiling instrumentation are very sensitive, saturating at power levels of ~1 microWatt per cm2, much lower than the irradiance of even the lowest power lasers. Thus, beam profiling is a lot about carefully attenuating the power level so the beam can be analyzed. This is critical because lasers designed for cutting sheet steel will also have no trouble cutting through a beam profiler if the beam power isn't attenuated!
The good news is there are reliable methods to reduce the beam power to levels required while preserving the beam profile integrity.

640x640transp Antireflection Coatings for High-Power Fiber Laser Optics
640x640transp The  nature of macro-materials processing applications, such as cutting and welding metal sheets, requires laser optics to perform properly at correspondingly high laser powers and power density levels. Minimizing losses due to absorption is of crucial importance to laser reliability and performance.
