These devices generate entities that are characterized in the FROG and SPIDER techniques. A technique using these devices was popularized by a paper on the dissociation of cyanogen iodide. (15[1])The (-5[1])state of a reaction (15[1])is studied using so-called “pumps” and “probes” (15[1])supplied by these devices (15[1])in a spectroscopy technique. That technique using these devices was pioneered by Ahmed Zewail in his study of (*) femtochemistry. (10[2])In another technique, these devices are used on a sample to trigger desorption, (10[1])after which the sample is ionized. (10[1])That “matrix-assisted” technique using these devices is often paired with time-of-flight mass spectrometry and is called MALDI. These devices are used to move atoms and nanoparticles in optical tweezing. For 10 points, name these devices which emit a coherent beam of light. ■END■ (10[1])
