In 1992 the researchers from the Quantum Electronics department of Vilnius University, led by prof. A. Piskarskas, introduced a new method - optical parametric chirped pulse amplification (OPCPA) - which nowadays is a basis for the laser systems producing high-power ultrashort light pulses. The group of High Intensity Laser Physics is developing a source of attosecond pulses employing a terawatt scale table top OPCPA system and a high-order harmonic generation technique for application in attosecond science research.
