PHOTON SCIENCE

DESY has joined Lasers4EU and adds five individual setups to the Lasers4EU portfolio. The installations are operated by the labs of Francesca Calegari, Franz Kärtner, Christoph Heyl and Ingmar Hartl.

Laboratories available for access via Lasers4EU are:

• Laboratory 1 (operated by Calegari Group): equipped with an attosecond beamline (STARLIGHT): this pump-probe setup is driven by sub-4fs NIR pulses (carrier wavelength 750 nm) obtained by hollow-core-fibre compression of a sub-20fs 10-mJ CEP-stable Ti:Sapph Laser operating at 1kHz repetition rate. It provides the unique availability of three different colors: 200-as nJ-level XUV pulses, sub-2fs UV pulses (carrier wavelength 250 nm) and sub-4fs NIR pulses. The uniqueness of this setup compared to other more conventional attosecond sources is the UV light source that delivers pulses short enough to explore the electron time scale in neutral molecules.
• Laboratory 2: equipped with sub-cycle parametric optical waveform synthesizer that coherently combines carrier-envelope phase stable ~ 8 fs IR-pulses with up to 0.6 mJ with carrier-envelope phase stable ~ 8 fs near-IR OPA pulses with up to 0.1 mJ pulse energy to sub-cycle pulses with about 3 fs duration at a rep. rate 1 kHz. This system can be used for strong-field research and is also coupled to a HHG beamline to generate soft-X-ray isolated attosecond pulses up to 450 eV.
• Laboratory 3: equipped with a 1 J, 300 ps at 1030 nm home-made laser system with the rep-rate 300 Hz for high-energy material science applications and THz generation.
• Laboratory 4: equipped with a 100 mJ, 900 fs at 1020 nm home-made laser system with the rep. rate 1 kHz for high-energy material science applications and THz generation.
• Laboratory 5 (operated by Hartl Group): equipped with a high-average power IR frequency comb laser. This laser provides laser pulses of 200 fs duration at 1030 nm, an average power of 80 W and a repetition rate of 65 MHz. The comb system is CEP- and repetition rate stabilized providing CEP stable operation supporting >48 hours without CEP phase slips. The laser can be optionally post-compressed to < 40 fs pulse duration. In addition, the laser can be frequency-tuned covering a tuning range of 1000 nm – 1060 nm. Next to the laser system, a passive enhancement cavity is available supporting a passive intra-cavity power enhancement to an average power of multiple kW.

Applications for access to the five laboratories at DESY have to be submitted via Lasers4EU
Criteria for eligibility are outlined on the Lasers4EU webpage

After Lasers4EU has granted access to the DESY laser facilities, applicants and all experiment participants have to register in our online portal DOOR
We will then inform you about all others steps to be taken to perform your experiment.
