Departments of Physics (DP), Szeged, is the largest laser-related institution in Hungary. The offered facility at DP has a unique feature that it incorporates three independent short- pulse laser systems at three base wavelengths (at 248 nm, 800 nm, and 1064 nm).

The High Intensity Laser Laboratory (HILL) operates a high-intensity femtosecond hybrid dye/excimer laser system offering the best laser parameters at 248 nm in Europe. The pulse energy is 80 mJ with 600 fs duration or 40 mJ with 150 fs pulse duration. The focussed intensity can surpass 1018 W/cm2 at several Hz repetition rate with a high temporal contrast. Several research projects were initiated in plasma physics, solid-state physics and micro material processing involving researchers both from the department and from other research institutes.

Activities of HILL: research and development of high-intensity KrF laser systems high-intensity laser-plasma interactions x-ray spectroscopy high-harmonics generation in gases interaction of laser with solids, such as laser processing and pulsed laser deposition pump-and-probe measurement for the study of the dynamics of solid and subpicosecond pulse interactions dynamic reflectivity measurements

The main workhorse of the TEWATI Laboratory is a hybrid (OPCPA + Ti:Sapphire) TW-class laser offering high contrast (109), 35 mJ, 20 fs pulses at 800 nm with 10 Hz repetition rate. Besides, tuneable, sub-30 fs pulses are also available in the visible (520-550 nm). The beam of the Nd:YAG pump laser is stabilised (< 15 µrad) and spatially filtered, so it contributes also as a stand alone device at its harmonics (532 nm and 266 nm) to most of the experiments in high precision laser surface processing.

A Q-switched, mode-locked picosecond Nd:YAG laser (Quantel) provides 80 mJ, 35 ps pulses at 1064 nm with 10 Hz repetition rate. The pulse energy at 532 nm and 355 nm is 10 mJ and 5 mJ, respectively.
