Abstract

Terahertz polariton sources based on the stimulated polariton scattering (SPS) can generate the terahertz wave with a narrow linewidth and continuous tunability. A single SPS process has limited conversion efficiency due to the Manley-Rowe relation. In this Letter, we implement a dual-Stokes cavity structure within an intracavity terahertz parametric oscillator (TPO) to achieve a two-order cascaded SPS process. As a result, the dual-Stokes cavity TPO demonstrates an increment of 29% in terahertz output power compared to that obtained in the non-cascaded SPS configuration.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
