To determine the difference between two lasing energy levels, one can use the relationship E = hf, where E represents energy, h is Planck's constant, and f is frequency. The frequency is inversely related to wavelength, allowing for the calculation of energy levels based on the emitted wavelength of light. The emitted photon energy corresponds directly to the difference between the two lasing energy levels. Clarification on terminology indicates that lasing energy levels refer to the states electrons transition between to release photons. Understanding these concepts simplifies the process of finding energy differences in laser systems.
