Abstract :
We developed injection-seeded terahertz wave parametric generator pumped by microlaser. Microlaser is the half palm-sized, LD-pumped single-mode microchip Nd:YAG laser, delivers 1.1 MW peak power pulses (530 muJ/pulse) with 430 ps pulse width at 100 Hz repetition rate. This THz-wave source generated narrow-linewidth THz-wave by injection seeding for the idler-wave. We observed its peak output power of more than 20 mW (2 pJ/pulse) at 1.6 THz and its palm size, portable source offer good advantages for many applications.
