Abstract :
We investigate Terahertz (THz) radiation from a ZnSe large aperture photoconductive antenna (LAPCA). The saturation fluence is seen to be significantly different for above and below band-gap excitation, and in comparison to GaAs substrates, shows strong potential as a high-power THz emitter.
