Název v původním jazyce

The current commissioning results of the Allegra kilohertz ultra-fast high-energy laser system at ELI-Beamlines

Popis výsledku v původním jazyce

The Allegra laser system is designed to provide sub-20 fs pulses with tens of mJ of energy with exceptionally high contrast at a 1 kHz repetition rate. It is the main driver for high harmonic and plasma X-ray secondary sources at ELI-Beamlines facility. The system is based on 7 stages of picosecond OPCPA pumped by 5 Yb:YAG thin-disk picosecond lasers and has been already commissioned at a preliminary energy level of 30 mJ and compressed by 90% efficient chirped mirror compressor to less than 15 fs. Even at this 30 mJ preliminary energy, Allegra has been successfully used to drive a high harmonic generation experiment. In this paper, we present an overview of Allegra system and the current state of deployment with an outline of the path towards an output energy of 50 mJ and above.
