TOM 8 Non-linear and Quantum Optics

Microcombs based on laser configuration: laser cavity solitons in a nested cavity geometry

Alessia Pasquazi

University of Sussex, United Kingdom

We will summarize our latest results on laser cavity solitons microcombs,

Here we discuss the figures of merit which allow us to evaluate the performance of laser cavity soliton microcombs produced by a system based on a Kerr microresonator nested in an amplifying cavity. Moreover, taking advantage of state-of-the-art metrological tools, including a real-time Dispersive Fourier Transform, we will present our latest results on their dynamics, which include the observation of their formation and subsequent interactions.

TOM 8 Non-linear and Quantum Optics

Free-running single-cavity dual-comb optical parametric oscillator in the mid-infrared

Carolin Patrizia Bauer, Justinas Pupeikis, Benjamin Willenberg, Christopher Richard Phillips, Ursula Keller

ETH Zurich, Switzerland

We demonstrate a dual-comb 80-MHz OPO from a single-cavity. The repetition-rate difference is 49 Hz. Each comb has >280-mW average power at 3500 nm, with ultra-low RIN below -155 dBc/Hz at MHz frequencies.

Sources of Water-Window Radiation at 100 kHz

Pierre-Alexis Chevreuil, Stefan Hrisafov, Fabian Brunner, Justinas Pupeikis, Christopher R. Phillips, Lukas Gallmann, Ursula Keller

ETH Zurich, Switzerland

We explore the generation of water-window radiation (283-543 eV, i.e. 2.3-4.4 nm) with two sources of ultrafast pulses centered at 0.8 µm and 2.2 µm. With the 2.2-µm beam, we generate high-harmonics in a phase-matched regime, while we operate the 0.8 µm in a high-intensity regime (Ipeak ≈ 2.6×10^16 W/cm^2), where the observation of a plateau in the 350-600 eV region can be explained by non-adiabatic self-phase-matching. We find that soft X-rays (SXR) up to 1.3 keV are generated using krypton or xenon gas targets.

Comparative study on highly efficient THz generation by optical rectification of mid-IR pulses in the organic crystal DAST

Claudia Gollner1, Rokas Jutas1, Mostafa Shalaby2,3, Corinne Brodeur2, Ignas Astrauskas1, Andrius Baltuška1,4, Audrius Pugžlys1,4

1TU Wien, Austria; 2Swiss Terahertz Research-Zurich, Switzerland; 3Key Lab of Terahertz Optoelectronics, China; 4Center for Physical Sciences & Technology, Lithuania

We present a comparative study on efficient THz generation by optical rectification (OR) of 3.9 μm and 1.95 μm pulses in DAST, achieving up to 40 MV/cm field amplitudes. At 1.95 μm we find that low linear and multi-photon absorption in combination with cascaded OR leads to record optical- to THz conversion efficiencies approaching 6%. The observed high sensitivity of the THz generation to the parameters of the mid-IR driving pulses motivates an in-depth study of the underlying interplay of nonlinear wavelength- and intensity-dependent effects.
