Abstract :
We report a very compact, laser diode end-pumped THz laser source, which utilizes two resonators to generate frequency-tunable radiation across the range 1.53-2.82 THz via stimulated polariton scattering (SPS) in a Mg:LiNbO3 crystal. To the best of our knowledge, this THz system operates with the lowest pump power threshold (2.4 W), and highest conversion efficiency (6.45ţW average output power at 1.82 THz for 5 W input diode pump power) ever reported for a THz source based on SPS.
