Abstract

Wavelength-tunable stimulated polariton scattering (SPS) in intracavity KTiOPO4 (KTP) crystal is demonstrated for the first time, with SPS threshold intensity as low as 22MW/cm2. The fundamental laser field at 1064nm is shifted via Stimulated Raman Scattering (SRS) and cascaded up to third order on the KTP transverse optical mode A1 of 268cm−1. Fundamental 1064nm and SRS-first-stokes-shifted 1095.5nm laser lines produced, simultaneously, tunable SPS output from 1080 to 1087nm and 1112 to 1119nm, respectively.
