Spatiotemporal Control of THz Pulses by Shaping the Laser Beam Transverse Profile in a Non Linear Rectifying Crystal
Résumé
We demonstrate that spatiotemporal properties of Terahertz (THz) pulses generated in a ZnTe crystal are controlled in the intermediate field by shaping the transverse spatial profile of the near infrared (NIR) femtosecond (fs) optical pump.
