Services currently offered by the infrastructure
The major laser systems and facilities at ULF-FORTH include:

  • Several Ti:Sa lasers with pulse duration down to >20 fs and energy <500 mJ/pulse at repetition rates of 10 Hz and 50 Hz. The Attosecond Science unit provides to Users energetic isolated pulses or trains of attosecond pulses. The beam line makes available non linear XUV autocorrelators and XUV-pump- XUV-probe delay lines as well as IR-XUV cross-correlators and delay lines. Ion mass, photoelectron and ion microscope with 1 μm resolution, XUV flat field spectrometer and other diagnostic facilities are also offered. Tunable XUV radiation is in the range (55-115 nm; 105-1011 photons/pulse per harmonic on target). Secondary ultra-short sources in the UV-NIR as well as an intense THz source (0.1-10 THz, with peak power allowing nonlinear studies) are also available.
  • A high-intensity excimer-based laser at 248 nm, with variable pulse duration
    (150 fs, 450 fs or 5 ps) and focused intensities <1016 W/cm2.
  • A complete range of tunable Vis-UV-VUV lasers (205–1800 nm; 5-20 ns), a White-light (500-2000 nm, 100MHz rep. rate, few μJ/pulse, <1ns) laser and CW diode lasers (402nm, 795nm, 1300-1340 nm, linewidth <1 MHz), all coupled to experimental workstations for atomic and molecular spectroscopy and chemical dynamics.
