Pulse train terahertz wave parametric generation

We generated terahertz (THz) pulse trains to enhance the average power of THz parametric generator. It was realized by dividing the pump beam into multiple pulses in an external cavity with amplifier and generating the THz wave. We confirmed pulse train generation of more than 20 pulses for the pump beam and observed an increase in THz wave output, suggesting that this method could potentially increase the average power.
