We demonstrate a frequency-tunable THz polariton source based on stimulated polariton scattering (SPS) in MgO:LiNbO3. The system produces THz emission using an intracavity shallow-bounce configuration. Continuously tunable THz emission across the fre

We demonstrate a new, to the best of our knlowledge, cavity design for terahertz (THz) lasers based on stimulated polariton scattering (SPS). The design simplifies the angle tuning of these lasers, which require non-collinear cavity fields at fundame

Laguerre-Gaussian (LG) modes [1] , [2] carry an annual spatial profile and a nonzero orbital angular momentum (OAM) owing to their on-axis phase singularity, and they offer us many applications, such as optical trapping and manipulation, laser nano/m

An Nd:YLF/KGW intracavity Raman laser in DBMC (double-beam-mode-controlling) configuration has been investigated in this work. The fundamental wavelength laser was generated using a Nd:YLF crystal pumped in DBMC configuration generating an emission w

By incorporating an etalon within an intracavity continuous wave terahertz polariton laser, we achieve a ten-fold reduction in linewidth, plus a factor of two increase in the THz output power.
