Room-temperature Quantum Cascade Laser Sources of Terahertz Radiation

Not Accessible

Your library or personal account may give you access


The development of room-temperature mass-producible 1-5 terahertz sources based on efficient intra-cavity frequency mixing in mid-infrared quantum cascade lasers will be discussed. Best devices provide over 0.1mW of terahertz output with over 0.4mW/W2 conversion efficiency.
