Second-harmonic Generated Holograms

Nonlinear Optics: Materials, Fundamentals and Applications, 2000
Second-harmonic generated holograms result from the second-harmonic crosscorrelation in a thin crystal of the optical field diffused by an object with a reference field. The SH field reconstructs a virtual holographic image in real time.

Adiabatic second-harmonic generation

Optics Letters, 2016
Adiabatic three-wave mixing processes enable broadband, efficient, and robust frequency conversion by slowly varying the phase mismatch between the interacting waves along the interaction region. Up until now, this method was mainly used in the case in which one of the waves was undepleted.

Second-harmonic generation in second-harmonic fiber Bragg gratings

Applied Optics, 1996
We consider the production of second-harmonic light in gratings resonant with the generated field, through a Green's function approach. We recover some standard results and obtain new limits for the uniform grating case. With the extension to nonuniform gratings, we find the Green's function for the second harmonic in a grating with an arbitrary phase ...

Ultrafast Adiabatic Second Harmonic Generation

Conference on Lasers and Electro-Optics, 2017
Abstract We introduce a generalization of the adiabatic frequency conversion method for an efficient conversion of ultrashort pulses in the full nonlinear regime. Our analysis takes into account dispersion as well as two-photon processes and Kerr effect, allowing complete analysis of any three waves with arbitrary phase mismatched ...

Mesoscopic second harmonic generation

Physical Review Letters, 1993
The low frequency second-harmonic transport response of multiprobe mesoscopic systems is analyzed using perturbation theory without explicit dephasing mechanisms. The intuitive conjecture that the second order transport current may be viewed as a linear conductance probing a distorted scattering potential is explicitly demonstrated in zero magnetic ...

Relationship between second-harmonic generation and electric-field-induced second-harmonic generation

Physical Review A, 1991
We calculate the electric-field-induced second-harmonic-generation (EFISH) susceptibility of a homogeneously broadened two-level system with permanent dipole moments. This susceptibility has contributions from the second-harmonic-generation (SHG) susceptibility of the same system without the presence of a dc field and the four-wave-mixing (FWM ...

Second Harmonic Generation

1971
Abstract : Investigations are being conducted under the subject contract with the objective of producing high average powers at a wavelength of 0.532 microns, with a short pulse and high repetition frequency format. The program objectives are to be achieved by utilizing a high average power CW Nd:YAG laser combined with electro-optic Q-switching ...

Homodyne surface second-harmonic generation

Optics Letters, 1995
We demonstrate the application of the homodyne mixing technique to surface second-harmonic generation. The technique is shown to have advantages for improving the signal-to-noise ratio for background and detector-noiselimited experiments, for providing real-time measurement of the phase and magnitude of the surface susceptibility, and for ...
