Double pulse laser ablation and plasma: Laser induced breakdown spectroscopy signal enhancement

A review of recent results of the studies of double laser pulse plasma and ablation for laser induced breakdown spectroscopy applications is presented. The double pulse laser induced breakdown spectroscopy configuration was suggested with the aim of overcoming the sensitivity shortcomings of the conventional single pulse laser induced breakdown spectroscopy technique. Several configurations hav...

Role of laser pre-pulse wavelength and inter-pulse delay on signal enhancement in collinear double-pulse laser-induced breakdown spectroscopy

a r t i c l e i n f o Keywords: LIBS Double pulse LIBS Plasma diagnostics LPP Dual-pulse (DP) laser-induced breakdown spectroscopy (LIBS) provides significant improvement in signal intensity as compared to conventional single-pulse LIBS. We investigated collinear DPLIBS experimental performance using various laser wavelength combinations employing 1064 nm, 532 nm, and 266 nm Nd:YAG lasers. In p...

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...
