Abstract :
We demonstrated a novel single longitudinal mode dual-wavelength fiber ring laser with continuously tunable wavelength spacing. Continuous-wave Terahertz radiation from sub-THz to 2 THz was generated through difference-frequency generation of two laser wavelengths in a nonlinear DAST crystal.
