Description
I will describe recently performed experiments demonstrating nonlinear x-ray wave-mixing including x-ray and visible wave mixing [1], x-ray second harmonic generation [2], and x-ray parametric down-conversion [3]. I will present theoretical studies of difference-frequency generation of optical radiation from two-color x-ray pulses [4], and x-ray-pulse characterization by spectral shearing interferometry [5]. I will discuss future directions of exploring nonlinear and quantum effects in the x-ray regime. For example, x-ray parametric down-conversion may be developed into a very powerful method to study fundamental effects in quantum optics. X-ray and visible mixing may lead to atomic scale resolution techniques to study chemical bonds. Nonlinear techniques are expected to be useful in the inspection of sub-femtosecond temporal pulses.
