Large nonlinear phase shifts in second-order nonlinear-optical processes.
We show that processes such as second-harmonic generation and subsequent downconversion, and parametric mixing in general, can lead to large field-dependent phase shifts for the input beams under a variety of conditions.
متن کاملResonant second-order nonlinear optical processes in quantum cascade lasers.
We demonstrate an efficient intracavity nonlinear interaction of laser modes in a specially adapted quantum cascade laser. A two-wavelength quantum cascade laser structure emitting at wavelengths of 7.1 and 9.5 micrometer included cascaded resonant optical intersubband transitions in an intracavity configuration leading to resonantly enhanced sum-frequency and second-harmonic generation at wave...

متن کاملSurface second-order nonlinear optical activity
Following the recent observation of a large second-harmonic intensity difference from a monolayer of chiral molecules with left and right circularly polarized light, the scattering theory is generalized and extended to predict linear and circular intensity differences for the more versatile sum-frequency spectroscopy. Estimates indicate that intensity differences should be detectable for a typi...
