WebNov 18, 2024 · Optical pumping creates a population of singlet excitons in rubrene (S 1 = 2.2 eV), some of which undergo singlet-exciton fission to create triplet–triplet pairs (T 1 = 1.14 eV), which may then recombine to form a singlet exciton or decay to the ground state. WebOptical pumping in lasers involves at least three different energy levels. In the simplest case, laser-active ions are pumped from their ground state to a higher-lying level, from where they undergo a quick radiative or non …
