Abstract

We demonstrate the first room temperature continuous wave THz sources based on intracavity difference frequency generation from mid-infrared quantum cascade lasers. This accomplishment was enabled by integration of several key technologies, resulting in a new high efficiency waveguide design and improved thermal dissipation. Room temperature single mode emissions at 3.6 THz with an emitting power of 3 μW and a mid-IR-to-THz conversion efficiency of 0.44 mW/W² are obtained in continuous wave mode. THz peak power up to 1.4 mW in pulsed mode operation with a mid-IR-to-THz conversion efficiency of 0.8 mW/W² at 3.5 THz is also demonstrated.
