What is Femtosecond Laser Ablation?
Femtosecond Laser Ablation (fs-LA) is an in-situ micro-sampling technique based on ultrashort femtosecond laser pulses. Unlike nanosecond laser ablation, which relies on a heating–melting–vaporization process, fs-LA removes material through a “Coulomb explosion” mechanism, enabling a near-athermal (“cold”) ablation process. In essence, fs-LA is a process that outruns thermal diffusion, using ultrafast laser pulses to minimize heat transfer, thus serving as an ideal sampling technique for high-precision micro-analysis.
When coupled with Inductively Coupled Plasma Mass Spectrometry (ICP-MS), the technique virtually eliminates thermal effects and generates fine, homogeneous aerosol particles. This optimizes ionization and transport efficiency within the ICP-MS system, enhances signal intensity and stability, enabling high-sensitivity, high-precision and high-spatial-resolution analysis for elements and isotopes with minimal matrix effect.
