Abstract

We demonstrated a pulse-to-pulse frequency-tunable LiNbO3 terahertz-wave parametric oscillator, pumped with a Q-switched Nd:YAG laser. Rapid tuning from 1 to 2 THz, with random frequency accessibility, was achieved by rotating the pump beam angle using an optical beam scanner and a telescope.
