In this paper we study average-power scaling of multi-cycle terahertz sources using periodically poled lithium niobate wafer stacks driven by high-repetition-rate ytterbium lasers. The study identifies beam focusing from nonlinear and thermal lensing effects as a key limitation and presents mitigation strategies for future power scaling.

New Publication

Terahertz technology has been severely limited by low-power sources. Our perspective article highlights how high-power ytterbium lasers are driving ultrafast THz sources toward watt-level average power. This laser technology promises to revolutionize THz applications by greatly improving measurement speed, signal quality, and dynamic range.
