摘要
A high repetition rate,picosecond terahertz(THz)parametric amplifier with a LiNbO3(LN)crystai has been demonstrated in this work.At a 10 kHz repetition rate,a peak power of 200 W and an average power of 12 pW have been obtained over a wide range of around 2 THz;at a 100 kHz repetition rate,a maximum peak power of 18 W and an average power of 10.8 pW have been obtained.The parametric gain of the LN crystal was also investigated,and a modified Schwarz-Maier model was introduced to interpret the experimental results.
