FEL: a Gentle Touch of the Laser

... the advent of the MALDI (matrix assisted laser desorbtion/ionization) technique, in which a substance placed in a special matrix is exposed to a high-power UV-laser pulse which lasts 10 -9 —10 -6 seconds. This leads to the process of the so-called ablation (sublimation) of the substance studied, in which molecules and their fragments in the form of ions fly off the substrate surface and enter a high-resolution mass spectrometer. Because the quantum energy of the laser radiation is high enough, ...
