We have developed injection-seeded terahertz-wave parametric generator pumped by a microchip Nd:YAG laser. This generated high peak power, tunable, narrow-linewidth terahertz wave with injection seeding by an external cavity diode laser. We observed terahertz wave, peak power of more than 30 W, tunable range from 0.9 to 3.1 THz, linewidth of less than 10 GHz.
