Plasma-assisted coherent backscattering for standoff spectroscopy. Academic Article uri icon


  • We show that an intense coherent backward signal can be generated through a Raman-type four-wave-mixing process using forward propagating fields only. Phase matching for this process is achieved through a plasma modulation of the refractive index. Applications to standoff spectroscopy are discussed.
