High power terahertz
WebJul 26, 2016 · Terahertz quantum cascade lasers with a record output power up to ∼0.23 W in continuous wave mode were obtained. We show that the optimal 2.9-mm-long device operating at 3.11 THz has a low threshold current density of 270 A/cm 2 at ∼15 K. The maximum operating temperature arrived at ∼65 K in continuous wave mode and the … Webenergy (>150 MeV) electrons do not necessarily yield high-power terahertz radiation. Instead, low-energy but high-charge electrons can produce much stronger terahertz radiation.
