- Although the ultrashort solitons described above have so far only been generated using a GaAs: InGaAs laser, nothing inherent to the technique restricts it to a specific material system.
- According to the uncertainty principle, these ultrashort pulses would have a very wide spectrum of energies - with some photons in the gamma radiation range, having more than 1 MeV of energy.
- Physicists have used ultrashort pulses of light to control the motion of electrons ejected from molecules and to produce electron beams just a few nanometres in length.
