FEMTOSECOND LASERS Femtosecond Femtosecond Lasers Lasers Multi TW Few cycle OPCPA systems Picosecond Lasers Nanosecond Lasers Unique OPCPA based laser system, providing ~15 terawatts of output power at 1 kHz repetition rate and an 8 fs pulse duration. Has been designed and built for ELI-ALPS facilities located in Szeged, Hungary Since their invention, lasers have been extremely effective to improve our understanding of the molecular and atomic structure of matter and the associated dynamical events. However, laser pulse energy was not enough to probe deeper – into nucleons and their components the quarks or to dissociate the vacuum. A new type of large-scale laser infrastructure specifically designed to produce the highest peak power and focused intensity was established by the European Community: the Extreme Light Infrastructure (ELI). ELI was designed to be the first exawatt class laser facility, equivalent to 1000 times the National Ignition Facility (NIF) power. Producing kJ of power over 10 fs, ELI will afford wide benefits to society ranging from improvement of oncology treatment, medical and biomedical imaging, fast electronics and our understanding of aging nuclear reactor materials to development of new methods of nuclear waste processing. UltraFlux Custom The facility will be based on four sites. Three of them are implemented in the Czech Republic, Hungary and Romania. ELI-ALPS based in Szeged (Hungary), one of the three pillars of the Extreme Light Infrastructure, will further deepen knowledge in fundamental physics by providing high repetition rate intense light pulses on the attosecond timescale. Current technological limitations will be overcome by use of novel concepts. The main technological backbone of ELI-ALPS will be optical parametric chirped-pulse amplification (OPCPA) of few-cycle to sub-cycle laser pulses. Pumped by dedicated all-solidstate short-pulse (ps-scale) sources and their (low-order) harmonics, this approach will be competitive with conventional (Ti:Sapphire laser based) femtosecond technology in terms of pumping efficiency and will dramatically outperform previous technologies in terms of average Driven by low maintenance cost diode-pumped and industrytested Yb:KGW and Nd:YAG lasers running at 1 kHz repetition rate > 120 W average power combined with > 15 TW peak power, along with sub-250 mrad carrierenvelope phase stability (CEP) and sub-8 fs pulse duration at a center wavelength of 900 nm Amplified Spontaneous Emission (ASE) – free, passively CEP stabilized pulses have excellent stability of output parameters over 24 hours of continuous operation Despite its unique set of specifications, it is still a table-top system A sophisticated self-diagnostic system allows hands-free operation and output specification stability all day long without operator intervention Fundamental frontier particle physics research Nuclear Photonics Attosecond pulse generation X-ray generation High harmonic generation Wake field particle acceleration

FEMTOSECOND LASERS power, contrast, bandwidth, and - as a consequence - degree of control of the generated radiation. The ELI-ALPS laser architecture will consist of three main laser beamlines, operating at different regimes of repetition rates and peak powers: High Repetition Rate (HR): 100 kHz, > 5 mJ, < 6 fs, Single Cycle (SYLOS): 1 kHz, > 120 mJ, < 8 fs, High Field (HF): 10 Hz, 34 J, < 17 fs. The Single Cycle Laser SYLOS laser system is based on OPCPA (Optical Parametric Chirped-Pulse Amplification) technology, developed at Vilnius university. Unlike other TW-level systems available in the...
