A New Strategy for Multi-Element Quantification in Oxide Materials

A study introduces a chemically constrained, two-step Calibration-Free Laser-Induced Breakdown Spectroscopy (CF-LIBS) strategy for multi-element quantification in oxide materials. The published paper is entitled, “A chemically constrained two-step calibration-free LIBS strategy for multi-element quantification in oxide materials.” The research resolves a long-standing analytical trade-off in CF-LIBS: Balancing the high-density plasma conditions required for thermodynamic modelling … Continue reading

Evaluating Structural Heterogeneity in Porous Metallic Foams

Evaluating structural heterogeneity in porous metallic foams has long been a challenge for standard non-destructive testing. While Laser-Induced Breakdown Spectroscopy (LIBS) offers rapid surface diagnostics, rough or porous surfaces often trigger uneven laser ablation and plasma plume instability. This instability leads to significant spectral fluctuations, hindering accurate porosity classification. Recent research introduces a data-driven multimodal … Continue reading

Benefits of Laser-Induced Periodic Surface Structures

When people think of Laser-Induced Breakdown Spectroscopy (LIBS), chemical analysis is usually the first thing that comes to mind. Whilst this remains a strong core focus at LTB Lasertechnik Berlin, their LMT team is pushing laser processing further with LIPSS (Laser-Induced Periodic Surface Structures). LIPSS uses ultrashort laser pulses to generate self-organized micro- and nanostructures … Continue reading

How Can Spacecraft Breakup Events Be Identified during Re-Entry?

A recently published study, entitled “Spectral markers for re-entry event identification,” investigates the use of spectral markers — materials designed to emit characteristic spectral signatures — during re-entry that can be detected by ground or airborne observation systems. Researchers from evaluated six candidate materials under representative re-entry conditions in the PWK4 plasma wind tunnel. Using … Continue reading
