Spectral gain investigation of large size OPCPA based on partially deuterated KDP

EPJ Web of Conferences 167 (2018)

M Galimberti, A Boyle, IO Musgrave, P Oliveira, D Pepler, W Shaikh, TB Winstone, A Wyatt, C Hernandez-Gomez

© The Authors, published by EDP Sciences, 2018. The Optical Parametric Chirped Pulse Amplification is one of the most promising techniques to deliver 20PW laser system. The already available KD∗P in large size is a good candidate as nonlinear crystal. In this article we report the experimental analysis of the spectral small signal gain for KD∗P at 70% deuteration level for different phase matching and non-collinear angle. The data is also compared with a theoretical model.

Multi-color carrier-envelope-phase stabilization for high-repetition-rate multi-pulse coherent synthesis.

Optics letters 40 (2015) 1208-1211

RA McCracken, I Gianani, AS Wyatt, DT Reid

Using a zero-offset carrier-envelope locking technique, we have synthesized an octave-spanning composite frequency comb exhibiting 132-attosecond timing jitter between the constituent pulses over a one-second observation window. In the frequency domain, this composite comb has a modal structure and coherence which are indistinguishable from those of a comb that might be produced by a hypothetical single mode locked oscillator of equivalent bandwidth. The associated phase stability enables the participating multi-color pulse sequences to be coherently combined, representing an example of multi-pulse synthesis using a femtosecond oscillator.

Attosecond sampling of arbitrary optical waveforms

2013 Conference on Lasers and Electro-Optics Europe and International Quantum Electronics Conference, CLEO/Europe-IQEC 2013 (2013)

Arbitrary waveform synthesis [1] offers the possibility to study and control electronic and nuclear processes with attosecond temporal resolution [2], and to enable 'sub-cycle' pulses and optimize high harmonic generation (HHG) [3, 4]. Appropriate metrology is critical to ensure the correct waveform is generated at the location of the experiment. Solutions to this measurement problem must deliver (a) adequate bandwidth; (b) sufficient efficiency; (c) sensitivity to phase across well-separated spectral components; (d) sensitivity to carrier-envelope phase (CEP); (e) reliable calibration procedures that can account for propagation between the measurement instrument and the experiment itself. Here we describe an experimental demonstration of the first all-optical method to characterize in-situ the real electric field of an arbitrary optical waveform based on HHG. © 2013 IEEE.
