(color online) Characteristic energy scales of excitations in solids. The energy range of table-top lasers, low energy free electron laser (FEL) facilities, and a few measurement methods are added to a figure published in Ref. [1]. A few abbreviations: DFG, difference frequency generation; OPA, optical parametric amplifier; QCL, quantum cascade laser.
