High-peak-power and narrow-linewidth terahertz-wave generation pumped by a microchip Nd:YAG laser

We have developed injection-seeded terahertz-wave parametric generator pumped by a amplified microchip Nd:YAG laser. This generated high-peak-power, narrow-linewidth and tunable terahertz-wave with injection seeding by an amplified external cavity diode laser. We observed tunable terahertz-wave, peak power of more than 120 W and linewidth of less than 10 GHz by calibrated pyroelectric detector.
