LASER 2 Duha: 100 TW, 2 J, 50 Hz
The L2 DUHA beamline is designed to be a high repetition rate 100 TW-class laser. The laser system amplifies a supercontinuum source up to multiple Joules via optical parametric chirped pulse amplification (OPCPA). The broad, flat amplification bandwidth allows compression to 25 fs on the output.

At the heart of the system is a cryogenically cooled Yb:YAG multislab diode pumped solid state laser (DPSSL) which serves as the OPCPA pump.
