Description
In the framework of a joint laboratory between INPHYNI and FASTLITE, we disclose the use of thick nematic liquid crystals to the temporal shaping of ultrashort pulses. We first propose to exploit the large and electrically controllable birefringence of nematic liquid crystals for precise control of the group and phase delays of femtosecond pulses, which is realized by appropriately addressing one or two electrically-driven cells. We then present an innovative thermo-optically addressed liquid crystal device, enabling continuous spectral phase shaping over a spectral bandwidth spanning from 540nm to 2500nm (450Thz). The modulation dynamic is large enough to shape single-cycle pulses.
