Transient Absorption Helps Distinguish Excitation Values . W?RZBURG, Germany, March 28, 2023 — Since the 1970s, researchers have struggled with the same problem: Shining a laser on a sample can excite it not just once, but several times per experiment. As a result, measurement results of the single excitation and the multiple excitations overlap and often cannot be separated. This makes it difficult to draw conclusions about the material being studied. To remedy this...
