Nonlinear phase change in type II second-harmonic generation under exact phase-matched conditions.
The process of type II second-harmonic generation has been investigated theoretically. It is found that, unlike in the process of type I second-harmonic generation, phase matching is not necessary for a significant shift of the pump wave phase to be produced. The simple inequality of the intensities of interacting waves suffices for this effect to occur.
متن کاملAtomically phase-matched second-harmonic generation in a 2D crystal
Second-harmonic generation (SHG) has found extensive applications from hand-held laser pointers to spectroscopic and microscopic techniques. Recently, some cleavable van der Waals (vdW) crystals have shown SHG arising from a single atomic layer, where the SH light elucidated important information such as the grain boundaries and electronic structure in these ultra-thin materials. However, despi...
متن کاملQuasi-phase-matched backward second-harmonic generation by complementary media in nonlinear metamaterials.
High efficiency of the second-harmonic and sum-frequency generation can be obtained in optical superlattice by using the conventional quasi-phase-matched (QPM) method. Although this trick can be played on the acoustic wave, the media with negative nonlinear parameters are not common in acoustics. Furthermore, the QPM method used in acoustic metamaterials has been less studied. In this work, a p...
متن کاملPulse measurements by randomly quasi phase matched second harmonic generation
We demonstrate experimentally the frequency doubling in disordered quadratic nonlinear media in the regime of total internal reflection of the fundamental beam. We show how the transversely emitted second harmonic can be employed for an efficient characterization of short laser pulses. (Some figures in this article are in colour only in the electronic version) Wavelength conversion of light via...
متن کاملMeasurement of nonlinear optical coefficients by phase-matched harmonic generation
A wide range of nonlinear optical coefficients and various systems of notation have been used to describe optical second-harmonic generation (5MG). To avoid possible confusion, the techniques of optical nonlinear coefficient measurement and the elementary theory of SHG are briefly reviewed. Absolute and relative nonlinear coefficient measurements by phase-matched SHG are described. The followin...
