Frequency Generation

We have developed a continuous wave THz Signal Generator on the principle of Difference Frequency Generation in a GaP crystal and constructed a high accurate CW THz spectrometer using it as a light source. Combining with a bolometer detector cooled by a mechanical cooler, the spectrometer is now working as non-stop system. Increasing the power of CW THz wave up to 100 nW, uncooled detector or camera is now available. This is the first report of CW THz beam observation generated at the surface of GaP crystal.
