Exactly integrable model of three-wave mixing in an inhomogeneous nonlinear medium
Zhuravlev V. M.
A Lagrange identity for conjugate equations is used to construct a Lax representation for an exactly integrable model of three-wave mixing in an inhomogeneous medium with four arbitrary functional parameters: the group velocities and refractive indices of the two primary waves.© 1995 American Institute of Physics.
