This femtosecond laser is an oscillator and a regenerative Ti: sapphire amplifier whose output is a pulse train of 40 fs. And 2 mJ. The team of femtoseconds also includes two parametric amplifiers (OPA), tunable in the range 240-2100 nm. Recently extensions have been implemented to the system which allow tuning the system to 200 nm.
