Power scalable compact THz system based on an ultrafast Yb-doped fiber amplifier

A power-scalable approach for THz generation is demonstrated using optical rectification in GaP pumped by a high power ultrafast Yb-doped fiber amplifier operating at 1.055 mum. A 120-MHz-repetition-rate pulse train of single-cycle THz radiation with 6.5 muW average power is generated using 10 W fro...

description A power-scalable approach for THz generation is demonstrated using optical rectification in GaP pumped by a high power ultrafast Yb-doped fiber amplifier operating at 1.055 mum. A 120-MHz-repetition-rate pulse train of single-cycle THz radiation with 6.5 muW average power is generated using 10 W from a parabolic fiber amplifier. Analysis of the THz power scalability indicates that due to the unique advantages offered by ultrafast optical rectification in GaP and due to the power scalability of fiber lasers, this approach has the potential to generate single-cycle THz pulse trains with average powers up to several mW.
