Properties of Alexandrite Lasers

  • John C. Walling
Part of the NATO ASI Series book series (NSSB)


The properties of electrons and electronic states are well suited for storing energy to be emitted as laser radiation. However, as quantum mechanics dictates all bound electronic states have discrete energy. Tunable lasers must be obtained, therefore, by means of either free electron states or by modifying (modulating) the electronic Hamiltonian. In certain classes of lasers, the electronic Hamiltonian is rendered continuously time variant by interactions with vibrations which participate directly in the stimulated emission event, such that part of the stored electronic energy is carried away by vibrational quanta. Dye lasers operate in this way as do a less well known but earlier class, the “phonon terminated,” or “vibronic” solid state laser, of which alexandrite is a prime example.
