Laser Induced Flourescence (LIF)

Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light.

TOOLS

Hybrid Raman-LIF-LIBS System

The instrument is a laboratory compact hybrid Raman-LIF-LIBS system based on the excitation of the three types of spectroscopic signals with a Q-Switched Nd:YAG laser (LS-2147, Lotis II) operating at 532, 355 or 266 nm, at a repetition rate of 10 Hz and delivering pulses of 17 ns with Gaussian-like spatial profile. The linearly polarized...
