Study of Surface Damage caused by Laser Irradiation for Quantitative Hydrogen Analysis in Zircaloy using Laser-induced Plasma Breakdown Spectrometry

The surface damage caused by laser irradiation is studied to investigate the possibility of performing a depth-profile analysis of the hydrogen concentration in zircaloy-4 alloys using laserinduced plasma breakdown spectrometry. After laser irradiation, a heat-affected zone extending about 3 μm down from the top surface can be seen. The depth of this heat-affected zone is independent of the las...

Stand-off Planetary Surface Analysis Using Laser-induced Breakdown Spectroscopy and Laser-induced Plasma Ion Mass

Introduction. Characterization of useable planetary materials will require high sampling throughput. Although remote observations from orbiting spacecraft provide spatially wide coverage, they do not, by themselves, provide sufficient information for materials utilization purposes. On the other hand, active rover-based in-situ analyses can provide detailed geological information but can be very...

Early stage expansion and time-resolved spectral emission of laser-induced plasma from polymer

In the nanosecond laser ablation regime, absorption of laser energy by the plasma during its early stage expansion critically influences the properties of the plasma and thus its interaction with ambient air. These influences can significantly alter spectral emission of the plasma. For organic samples especially, recombination of the plasma with the ambient air leads to interfering emissions wi...

Damage inspection of fiber reinforced polymer-concrete systems using a distant acoustic-laser NDE technique

In this paper, a distant acoustic-laser NDE technique is proposed, utilizing a high powered standoff parametric acoustic array (PAA) and laser Doppler vibrometry (LDV), for the detection of debonding and delamination in multi-layer composite systems. Fiber-reinforced polymer wrapped concrete cylinder specimens with artificial defect were manufactured and used in the validation of the technique....
