Abstract
A new proposal for dynamically manipulating the polarization of a light wave brings this ability to various nonlinear optical media and high-power lasers.
Highlights
Controlling and manipulating the polarization state of light waves is crucial for many applications in various areas of physics and optics research and technology
We extend the linear theory of polarizationdependent wave mixing to arbitrary nonlinear media and propose a simple setup that should enable the practical application of these polarization mixing concepts in the “nonlinear” regime, i.e., where the intensity of the probe beam can be greater than the intensity of the auxiliary beam
This extends the concepts of polarization control in the linear regime, which we already demonstrated in plasmas [2], to a very wide variety of nonlinear optical media such as gases or fluids
Summary
Controlling and manipulating the polarization state of light waves is crucial for many applications in various areas of physics and optics research and technology. We extend the linear theory of polarizationdependent wave mixing to arbitrary nonlinear media and propose a simple setup that should enable the practical application of these polarization mixing concepts in the “nonlinear” regime, i.e., where the intensity of the probe beam (whose polarization state is being manipulated) can be greater than the intensity of the auxiliary beam (whose role is to control the polarization state of the probe). These schemes should be valid for any optical medium with an intensitydependent refractive index of the form n 1⁄4 n0 þ n2I.
