[10p-Z24-2] [The 4th Photonics Division Award Speech] Demonstration of tunable backward terahertz-wave parametric oscillation
Keywords:Nonlinear wavelength conversion, Terahertz-wave parametric oscillation, Quasi-phase-matching device
We demonstrated tunable backward terahertz (THz)-wave parametric oscillation. The oscillation was emerged by the simple scheme without cavity mirrors. Noteworthy, the tunability was provided by just rotating the angle of a nonlinear crystal. The capability would realize mobile and ubiquitous THz-wave sources combining with robots.
