Traceable Measurements of CW and Pulse Terahertz Power With Terahertz Radiometer

We report on traceable measurements of continues wave (CW) and pulse terahertz (THz) power with a THz radiometer. A sensitive THz radiometer with a broad bandwidth, high absorbance coating as absorber was fabricated. The absorber has an absorbance of higher than 99% in both 0.1 THz-3.0 THz region and in visible laser wavelengths range, which allows for an… CONTINUE READING
