We obtained a frequency tunable, low-coherence, picosecond, terahertz (THz) output with a high repetition rate from a picosecond Nd:YVO4 bounce laser in combination with tandem periodically poled stoichiometric lithium tantalate and 4′-dimethylamino-N-methyl-4-stilbazolium tosylate crystals. The frequency of the THz output was tunable in the range 2.1-7.1 THz with a linewidth of ∼3.5 THz at 2.2 THz. The THz output had a maximum peak power of ∼180 mW and an average power of ∼0.65 μW at 3.9 THz. This system has the potential to realize ultra-high speed, THz coherence tomography.
