A new compact laser source for portable LIBS applications
International audience; We present LIBS experimental results that demonstrate the use of a newly compact, versatile pulsed laser source in material analysis in view of research aiming at the development of portable LIBS instrumentation. LIBS qualitative analyses were performed on various samples and objects, and spectra were recorded in gated and non-gated modes. The latter is important because of advantages arising from size and cost reduction when using simple, compact spectrograph-CCD detection systems over the standard ICCD-based configurations. The new Nd3+:YAG laser source exhibited very reliable performance in terms of laser pulse repeatability, autonomy and interface. Indeed, it can…

A compact and portable laser-induced breakdown spectroscopy instrument for single and double pulse applications
Abstract We present LIBS experimental results that demonstrate the use of a newly developed, compact, versatile pulsed laser source in material analysis related to art and archaeological applications in view of research aiming at the development of portable LIBS instrumentation. LIBS qualitative analysis measurements were performed on various samples and objects, and the spectra were recorded in gated and non-gated modes. The latter is important because of advantages arising from size and cost reduction when using simple, compact spectrograph-CCD detection systems over the standard ICCD-based configurations. The new laser source exhibited a very reliable performance in terms of laser pulse …

Comparison between 2 Different Composite Nd3+:YVO4 Crystals in a Fibre Coupled Diode Pumped Laser
International audience; We detail the performances of two composite Nd3+YVO4crystals, realised with two different sticking techniques. We tested them inside a fibre coupled diode end pumped laser.
