Description

In this contribution, we specifically explore  our THz source, driven by an ytterbium-fibre-based chirped-pulse amplifier system (from AFS GmbH). The system delivers ultrashort pulses of 300 fs duration with a maximum energy of 240 µJ at 330 kHz. A THz generation scheme based on optical rectification in a LiNbO3 prism combined with a stair-step reflective echelon for tilting the pump pulse front is exploited.
