3.4 THz quantum cascade laser operating above liquid nitrogen temperature

Williams, B.S.; Kumar, S.; Callebaut, H.; Hu, Q.; Reno, J.L.

Terahertz lasing in a quantum cascade structure in pulsed mode up to a temperature of 87K at a wavelength of λ= 88 μm (3.4 THz) has been obtained. At 5K, a peak power of approximately 3.4 mW is observed, with still ∼1 mW at 78K.
