Fiber-delivered Acoustic 3D Imaging System with Laser-induced Breakdown

Femtosecond fiber-laser-based laser-induced breakdown spectroscopy

This paper reports the LIBS studies on elemental composition detection and identification by employing a femtosecond (fs) fiber laser. High quality LIBS spectra were obtained in air using near-infrared fs fiber laser coupled with a broadband high sensitivity spectrometer without gating control. Specific ion and neutral emission lines of different materials have been characterized by line scanni...

Laser-induced breakdown spectroscopy of copper with a 2 μm thulium fiber laser

We report the first implementation of a 2 μm thulium fiber laser in a Laser-Induced Breakdown Spectroscopy system. Emission from plasma on copper samples was analyzed from 200 to 900 nm. The low ablation fluence (<100 J.cm −2 ) and 200 ns pulse duration lead to a plasma with neither continuum emission, nor air emission in the near-infrared region. ©2010 Optical Society of America OCIS codes: (0...

Qualitative assessment of laser-induced breakdown spectra generated with a femtosecond fiber laser.

This paper presents what is to our knowledge the first evaluation of laser-induced breakdown spectroscopy (LIBS) studies on elemental composition detection and identification by employing a femtosecond (fs) fiber laser. Qualitative LIBS spectra were obtained in ambient air using a 1030 nm fs fiber laser. Specific ion and neutral emission lines of different materials have been characterized, inc...

3D Imaging of Nanoparticle Distribution in Biological Tissue by Laser-Induced Breakdown Spectroscopy

Nanomaterials represent a rapidly expanding area of research with huge potential for future medical applications. Nanotechnology indeed promises to revolutionize diagnostics, drug delivery, gene therapy, and many other areas of research. For any biological investigation involving nanomaterials, it is crucial to study the behavior of such nano-objects within tissues to evaluate both their effica...
