We demonstrate a 80μJ, 5fs, CEP-stable injector with high spectro-temporal quality. The device relies on post-compression in a hollow-core fiber followed by XPW filtering and is an ideal seed for high-power high-contrast OPCPA systems.
An acousto-optic dispersive filter (AOPDF) is used to pre-compensate spectral narrowing and to measure (DazScope software from Fastlite) the spectral phase induced by SPM and then compensate for the measured phase distortion. The paper presents the results of SHG spectra versus chirp traces together with the extracted local chirp function for four states: initial state at low energy, coarsely optimized...
Sub-5fs pulses are generated at the mJ level through a hollow-core fiber seeded with circularly polarized pulses. The preservation of carrier-envelope phase of the hollow-core fiber compressor is also demonstrated.
Measurements and modeling of the propagation of the fundamental and the XPW signal emerging from a nonlinear crystal show how to manage self-phase modulation and self-focusing to improve conversion in a second crystal.
4.3 fs, 1 mJ pulses at 1 kHz are generated through hollow fiber seeded with circularly polarized laser beam. This technique provides an effective energy upscaling approach for hollow fiber compression technique.
We present automated optimization of the temporal duration of femtosecond pulses generated in a CPA laser system with high B-integral. Both phase measurement and correction were done by a single AOPDF within the CPA system.
We compare experimentally the performance of a linearly chirped waveguide grating with a uniform grating for coupling light to a vertical fiber. The measurements show the chirped grating reduces reflection and coupling loss by 2 dB.
