Harmonic Generation in Paramagnetic Spin Systems.

reportActive / Technical Report | Accession Number: ADA130895 | Open PDF

Abstract:

The theory of resonant second and third harmonic generation is considered and applied to the case of paramagnetic spin systems tuned by a magnetic field. Using available spectroscopic and material parameters, conversion efficiencies of around 25 seem feasible. Optical nonlinearities in semiconductor super-lattice are considered and shown to have large second order optical nonlinearities in the mid-infrared.
