We report the generation of CW THz radiation, generated via stimulated polariton scattering in MgO:LiNbO3. The system is capable of producing frequency tunable radiation across the range 1.5–2.3 THz and requires only 2.3 W incident diode pump power to reach threshold. Maximum THz output power of 2.3 μW has been detected for just 5.9 W incident diode pump power, at a frequency of 1.8 THz.
