Abstract :
We propose a novel method to realize widely tunable terahertz-wave generation from GaP by collinearly phase-matched difference-frequency generation. Our method makes it possible to achieve a wavelength-tunable output without decreasing the output efficiency, which can be used for wavelength sweeping in spectroscopy.
