Multiplier-based sources of terahertz power

The performance of terahertz sources based on frequency multipliers continues to improve in terms of power, maximum frequency and frequency agility. This talk will describe the range of performance that is possible with this technology; including narrow-band sources that generate greater than 400 mW above 100 GHz and broadly tunable sources that generate 10psilas of microwatts above 1 THz. This talk will also consider the unique source characteristics required by the wide range of applications being explored, and their impact on source performance and design. This includes the need for power modulation and pulsing, rapid frequency sweeping, achieving highly stable and phase locked signals, as well as phase locking the source to a heterodyne receiver.
