Abstract
The L1-Allegra laser (1 kHz, 50mJ pulse energy, 15 fs pulse duration) developed at ELI-Beamlines in Czechia is already being used for various scientific experiments. The femtosecond synchronization project (referred to as F-SYNC) aims to dramatically improve the experiments with L1-Allegra by providing another 1 kHz beam with arbitrary delay to L1 and femtosecond precision. Therefore, we have developed an independent auxiliary laser system inspired by the design of the L1-Allegra front-end with an output energy of approximately 13mJ at 1 kHz and bandwidth that supports compression to < 16 fs. In essence, F-SYNC consists of a master oscillator, a fiber seed distribution system, a pump laser with a grating compressor, a supercontinuum (SC) seed, and 3 stages of optical parametric chirped pulse amplification (OPCPA).
