Using lasers for generation of THz radiation
This talk will introduce the techniques used to generate THz radiation using various laser sources and summarize their respective advantages. It will then focus on the development and recent advances in intracavity THz lasers based on stimulated polariton scattering (SPS) achieved at Macquarie University. The talk will cover generation of THz radiation around 1-3 THz using MgO:LiNbO3 crystals and its extension to higher frequencies using RTP and KTP. It will discuss the laser design choices leading to higher efficiency and output power and mitigation of damage on optical components. I will conclude the talk with recent advances in continuous wave THz generation and linewidth narrowing techniques and discuss its importance for spectroscopic applications.
