“…The high frequency components appearing due to the parallel beam geometry can be eliminated by Fourier filtering [86] and the resulting non-interferometric FROG spectrogram can be inverted by established algorithms to retrieve information about the spectral phase of the pulse at the focus [87]. A similar approach was successively applied in a series of experiments by the Liu group, attaching a HNP on a fiber taper via a carbon nanotube [88,89] making it possible to manipulate the probe with high precision via a piezoelectric stage for acquiring autocorrelation traces at the laser focus, using the HNP as nonlinear medium. The same device was successively used to detect a holographic FROG trace probing the evolution of a pulse at different locations in space [90].…”

The combination of nonlinear optics and nanotechnology is an extremely rich scientific domain yet widely unexplored. We present here a review of recent optical investigations on noncentrosymmetric oxide nanoparticles with a large χ (2) response, often referred to as harmonic nanoparticles (HNPs). HNPs feature a series of properties which distinguish them from other photonics nanoprobes (quantum dots, up-conversion nanoparticles, noble metal particles). HNPs emission is inherently nonlinear and based on the efficient generation of harmonics as opposed to fluorescence or surface plasmon scattering. In addition, the fully coherent signal emitted by HNPs together with their polarization sensitive response and absence of resonant interaction make them appealing for several applications ranging from multi-photon (infrared) microscopy and holography, to cell tracking and sensing.

“…These advantages make NPs more cost effective and easier to handle than their bulk crystal counterpart. The SH emission from single nonlinear NPs [13][14][15][16][17][18] and nanotips 19 interacting with ultrafast pulses has recently been detected and studied.

Phase control of femtosecond pulses on the nanoscale using second harmonic nanoparticles

et al. 2014

Investigations of ultrafast processes occurring on the nanoscale require a combination of femtosecond pulses and nanometer spatial resolution. However, controlling femtosecond pulses with nanometer accuracy is very challenging, as the limitations imposed both by dispersive optics on the time duration of a pulse and by the spatial diffraction limit on the focusing of light must be overcome simultaneously. In this paper, we provide a universal method that allows full femtosecond pulse control in subdiffraction-limited areas. We achieve this aim by exploiting the intrinsic coherence of the second harmonic emission from a single nonlinear nanoparticle of deep subwavelength dimensions. The method is proven to be highly sensitive, easy to use, quick, robust and versatile. This approach allows measurements of minimal phase distortions and the delivery of tunable higher harmonic light in a nanometric volume. Moreover, the method is shown to be compatible with a wide range of particle sizes, shapes and materials, allowing easy optimization for any given sample. This method will facilitate the investigation of light-matter interactions on the femtosecond-nanometer level in various areas of scientific study.

“…Recently the SH emission from single non-linear NPs interacting with ultrafast pulses has been detected and studied. [16][17][18][19][20][21] Extremann et al 16 used single SH NPs to characterize broadband pulses with high spatial resolution using FROG; Wnuk et al 18 compared the SH response from NPs excited with chirped 200 fs and compressed 13 fs pulses; Aulbach et al 19 used the SH from NPs as a feedback signal for spatio-temporal focusing.…”

We provide a complete toolkit for coherent control experiments on the nano-scale. By exploiting the second harmonic emission from single (150 nm) nonlinear nano-particles, we show that ultrafast femtosecond laser pulses can be compressed and controlled in time with unprecedented spatial accuracy. The method is tested on various nano-particles of different sizes, shapes and materials, both dielectric BaTiO 3 , Fe(IO 3 ) 3 ) and metallic (Au) thus demonstrating its robustness and versatility.
