Terahertz Resonant Emission by Optically Excited Infrared‐Active Shear Phonons in KY(MoO4)2

Terahertz Resonant Emission by Optically Excited Infrared‐Active Shear Phonons in KY(MoO4)2

Abstract The generation of monochromatic electromagnetic radiation in the terahertz (THz) frequency range has remained a challenging task for many decades. Here, the emission of monochromatic sub‐THz radiation by optical phonons in the dielectric material KY(MoO4)2 is demonstrated. The layered cryst...
