Stabilization of terahertz beats from a pair of picosecond dye lasers by coherent photon seeding

Well-defined beats of terahertz frequencies have been generated by two synchronously-pumped mode-locked dye lasers stabilized by coherent photon seeding. External cavities ended by phase-conjugate mirrors were used to provide the necessary feedback. The two lasers were operated at different tunable wavelengths, and the beat frequency was scanned from 0.5 to 18 THz. In the absence of coherent photon seeding, the dynamics of pulse formation in each dye laser was subject to spontaneous emission noise, leading to a severe degradation of the beat signal.
