Combined visible and near-infrared OPA for wavelength scaling experiments in strong-field physics
Proceedings of SPIE SPIE 10088:Nonlinear Frequency Generation and Conversion: Materials and Devices XVI (2017)
Abstract:
We report the operation of an optical parametric amplifier (OPA) capable of producing gigawatt peak-power laser pulses with tunable wavelength in either the visible or near-infrared spectrum. The OPA has two distinct operation modes (i) generation of > 350 μJ, sub 100 fs pulses, tunable between 1250 - 1550 nm; (ii) generation of > 170 μJ, sub 150 fs pulses tunable between 490 - 530 nm. We have recorded high-order harmonic spectra over a wide range of driving wavelengths. This flexible source of femtosecond pulses presents a useful tool for exploring the wavelength-dependence of strong-field phenomena, in both the multi-photon and tunnel ionization regimes.High harmonic generation in gas-filled photonic crystal fibers
