We observe optical third harmonic generation from graphene and few-layer graphite flakes produced by exfoliation. The emission scales with the cube of the intensity of the incident near-infrared femtosecond pulses and has a wavelength that is one-third of the incident wavelength, both consistent with third harmonic generation. We extract an effective third-order susceptibility for graphene that is on the order of 1e-16 square meter per square volt, which is comparable to that for materials that…

Optical Third-Harmonic Generation in Graphene

We report strong third-harmonic generation in monolayer graphene grown by chemical vapor deposition and transferred to an amorphous silica (glass) substrate; the photon energy is in threephoton

Observation of optical second harmonic generation from suspended single-layer and bi-layer graphene

We have experimentally investigated the optical second harmonic generation (SHG) on suspended single-layer and bi-layer graphene sheets. By shining normally incident 800-nm light with polarization

Third-harmonic generation in ultrathin films of MoS2.

The demonstrated third-harmonic generation can be used for nonlinear optical identification of MoS2 atomic layers with high contrast, better distinguishing power of multilayers, and less restrictions to substrate selections.

Cavity enhanced third harmonic generation in graphene

Graphene displays a surprisingly large third order nonlinearity. Here, we report that conversion efficiencies approaching 10–4 are possible for third harmonic generation (THG). Moreover, the

Investigation of Second- and Third-Harmonic Generation in Few-Layer Gallium Selenide by Multiphoton Microscopy

This work reports on the nonlinear optical properties of few-layer GaSe using multiphoton microscopy, and finds that even the peak at the wavelength of 390 nm, corresponding to the fourth-harmonic generation or the sum frequency generation from third- Harmonic generation and pump light, was detected during the spectral measurements in thin GaSe flakes.

Enhanced third harmonic generation from sinusoidal graphene gratings

We investigate the nonlinear optical third harmonic generation of sinusoidal curved graphene which is placed on the dielectric substrate. Under transverse magnetic polarization, the third harmonic

Theory of high-order harmonic generation for gapless graphene

We study the high-harmonic spectrum emitted by a single-layer graphene, irradiated by an ultrashort intense infrared laser pulse. We show the emergence of the typical non-perturbative spectral

High-harmonic generation from monolayer and bilayer graphene

High-harmonic generation (HHG) in solids is an emerging method to probe ultrafast electron dynamics in solids at attosecond timescale. In this work, we study HHG from a monolayer and bilayer

Second harmonic generation in graphene dressed by a strong terahertz field

We observe enhanced second-harmonic generation in monolayer graphene in the presence of an ultra-strong terahertz field pulse with a peak amplitude of 250 kV/cm. This is a strongly nonperturbative

High harmonic generation in graphene: temporal and spectral properties

Graphene has been recently reported to have a damage threshold high enough to allow for the interaction with ultrashort laser pulses of intensities above 1013 W/cm2. It is natural to explore if this



Nonlinear optics.

In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
