Laser Beam Profiling in the Production Process [PDF]
Laser Technik Journal, 2010 AbstractLaser material processing is increasingly becoming more accepted in modern production lines. A growing number of production steps previously carried out by mechanical methods are being replaced by laser beam processing. The use of such high power laser beams requires adequate beam measurement technology to ensure product quality and to minimize

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
