“…The properties of the fundamental and second harmonic pulses are characterized using a spectrometer (HR2000, Ocean Optics) and a GRENOUILLE system (UPM 8-50, Newport). The estimated peak power of a single pulse is less than the critical power for selffocusing due to electronic (instantaneous) contribution of the χ (3) nonlinearity of the SBN crystal. At low average input powers the divergence of the fundamental beam after its propagation in the SBN crystal is defined by the focal spot (∼6.5 mrad @ 100 mW), whereas its spectral width is inversely proportional to the pulse duration.…”

“…In order to fulfill the required phase-matching condition, often layered or periodically poled media are used. The first successful experiments with TSH have been conducted in 1-2 µm thick quantum wells waveguide structures [3][4][5][6][7]. The emission of TSH from these waveguides is frequently termed as the surface emitting second harmonic generation.…”

“…The emission of TSH from these waveguides is frequently termed as the surface emitting second harmonic generation. As all these experiments used the counter-propagating short pulses the spatial distribution of the TSH represents the autocorrelation of the pulses and hence can be used for pulse duration monitoring [3,4].…”

Abstract:We investigate the transverse second-harmonic generation in as grown strontium barium niobate (SBN) crystals with a random structure of anti-parallel ferroelectric domains. We consider both, single and counterpropagating pulse geometries. We investigate polarization properties of the second harmonic signal and discuss applications of this process for short pulses characterization. PACS (2008):42.65.-k

ABSTRACT. By patterning the domains in ferroelectric crystals, it is possible to introduce periodic changes in the sign of the nonlinear susceptibility in waveguide frequency conversion devices. Appropriate choice of the spatial frequency of the modulation allows quasi -phasematching of any nonlinear interaction involving radiation in the transparency range of the crystal. Room temperature second harmonic generation of visible radiation and difference frequency generation of infrared radiation have been demonstrated.

We have theoretically investigated ultrafast surface-emitting second-harmonic (SH) generation from mode-locked laser pulses with arbitrary pulse shapes. The spatial dependence of the SH energy density per pulse is almost the same as the temporal profile of the SH power emitted from the entire surface per waveguide width for a long waveguide. For a sinc fundamental pulse, we have obtained, rich and unique, temporal, spatial, and spectral behavior of the second harmonic. We have found that both the temporal and spectral profiles of the emitted second harmonic depend on the location at the surface. These effects can be observed with lasers currently available, and used for auto correlation, in optical signal processing, optical communications, and practical frequency doubling of ultrafast optical pulses with an advantage of no broadening of the SH pulse. We have compared these results with those for a Gaussian fundamental pulse. After introducing saturation intensity to quantify the saturation regime, we have obtained quantitative expression on the second-harmonic intensity in terms of the pump and saturation intensities.
