Abstract
We report the generation of 200kW-peak-power coherent radiation at 53 microns from a Raman-suppressed stimulatedpolariton- scattering laser using a thin KTP gain crystal at room temperature. The far-infrared radiation consists of ~500 radiation cycles in an 83-ps pulse width. Such a far-infrared source has a comparable or higher peak power than a nominal THz free-electron laser.
