title: Stimulated polariton scattering in an intracavity RbTiOPO4crystal generating frequency-tunable THz output.
abstract: A high power, frequency-tunable THz source based on intracavity stimulated polariton scattering (SPS) in RbTiOPO4(RTP) is demonstrated for the first time. Frequency tunable THz output was obtained from 3.10 to 4.15 THz, with a gap at 3.17 to 3.49 THz, arising from the 104 cm-1A1mode in RTP. A maximum average output power of 16.2 µW was detected at 3.8 THz. This is the highest average output power ever reported for an intracavity polariton laser.
