“…12, uses a low frequency-noise laser-oscillator with a repetition frequency ν (46) = ν rf /46 = 62.08695 MHz with a 1030 nm central wavelength and bandwidth of ≈ 13 nm (FWHM), delivering an output power in excess of 100 mW. It is frequency locked on the optical master clock of ELI-NP-GBS that is distributed by a non stabilized fiber link [50]. The laser pulse is sent in a non-critical phase-matched secondary harmonic generator (SHG) based on a 7 mm long LBO crystal hold in a temperature-controlled oven that is set at 194 • C. The conversion efficiency is 18 % for standard operations.…”

“…The ELI-NP-GBS synchronization system has been manufactured by Menlo Systems [60] and consists in a rf reference clock ν rf = 2856 MHz, a subharmonic clock distribution and a client synchronization. The reference signal is provided by an ultra-low phase noise µ-wave crystal Reference Master Oscillator (RMO) [50]. The absolute jitter is measured below 60 fs on the range 10 Hz-10 MHz.…”

We report on the optical commissioning of the high power laser beam circulator (LBC) for the high brightness Compton γ-ray source Extreme Light Infrastructure for Nuclear Physics. Tests aiming at demonstrating the optical performances of the LBC have been realized with a low-power pulsed laser-beam system and without electron beam. We show that, with the developed alignment and synchronization methods coming from the LBC design study presented in the Dupraz et al. paper [1], the LBC enhances the laser-beam power available at the interaction point (IP) by a factor in excess of 25. This corresponds to a potential of bringing the average laser-beam power in excess of 1 kW when the LBC is injected with the interaction point laser-beam pulse energy of 400 mJ at 100 Hz.
