Direct measurements of temperature-dependent laser absorptivity of metal powders
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Here, a compact system is developed to measure laser absorptivity for a variety of powder materials (metals, ceramics, etc.) with different powder size distributions and thicknesses. The measured results for several metal powders are presented. The results are consistent with those from ray tracing calculations.
