TOM 8 Non-linear and Quantum Optics

Nanoscale nonlinear optics with structured media and structured light

Anatoly Zayats

King's College London, United Kingdom

Coherent and incoherent nonlinear optical effects play important role in photonics, laser physics and quantum optics. Weak nonlinearity of conventional materials can be enhanced by their nanostructuring or through metamaterial approach. Using complex vector beams with tailored distributions of the electric field amplitude and phase provides additional opportunities to manipulate nonlinear response. Here we will discuss new opportunities for controlling second-harmonic generation and Kerr-type optical nonlinearities combining metamaterials and vortex beams.

TOM 8 Non-linear and Quantum Optics

Nonlinear light scattering & imaging: Quantifying interfacial properties on the nanoscale

Sylvie Roke

EPFL, Switzerland

Nonlinear optics has come very far since the 1960’s, delivering a wide variety of light sources and methods to probe materials. In this presentation I will discuss 3 recent developments of nonlinear optical methods invented in my laboratory: Vibrational sum frequency scattering (SFS), high-throughput second-harmonic scattering (SHS) and imaging and their application to dynamic quantitative surface chemistry, biophysics and neuroscience.

We present a multiplexing acquisition for high spectral resolution Stimulated Raman Scattering (SRS) microscopy based on a dual-beam femtosecond laser. A multi-channel acousto-optical tunable filter generates spectral masks, given by the Hadamard matrix, by turning on and off different subsets of its 8 independent channels, corresponding to different wavelengths available within the broad bandwidth of the “pump” laser. The SRS spectrum is retrieved by using the inverse Hadamard matrix. When additive noise is dominating, spectral measurements performed with this method show two-times higher signal-to-noise ratio compared to single-wavenumber acquisitions.

Free-space dark pulse laser source based on sum-frequency generation

Martin Brunzell, Max Widarsson, Christoffer Krook, Laura Barrett, Andrius Zukauskas, Fredrik Laurell, Valdas Pasiskevicius

Royal Institute of Technology (KTH)

A mode-locked dark pulsed laser source operating at 1064 nm based on Nd:YVO4 is presented. The dark pulses were generated by inducing a time dependent loss through sum-frequency generation with a 1040 nm mode-locked Yb:KYW laser. Dark pulses with a 10 ps width and a modulation depth over 90% with 180 mW output power was generated.
