Hybrid architecture for high energy lasers delivering sub-500 fs pulses

An increasing number of scientific applications require highly energetic ultrafast laser system like OPA pumping, THz generation or filamentation. To address their requirements, Amplitude Systems is developing a versatile femtosecond laser system based on diode-pumped Ytterbium doped crystals at ambient temperature. An output energy of 74 mJ at 100 Hz was obtained with a pulse duration as short as 450 fs, which corresponds to a peak power of nearly 170 GW.
