Linearity of Fast and Highly Sensitive LiTaO3 Pyroelectric Detectors in the Terahertz Range
In response to single-cycle THz pulses, we measured the linearity parameter of lithium tantalate pyroelectric detectors, over nearly three orders of magnitude in pulse energy, up to 2 mu J. The response was linear up to 1 mu J pulse energy and 25 mu J/cm(2) energy flux, and sublinear at higher irrad...

| Tartalmi kivonat: | In response to single-cycle THz pulses, we measured the linearity parameter of lithium tantalate pyroelectric detectors, over nearly three orders of magnitude in pulse energy, up to 2 mu J. The response was linear up to 1 mu J pulse energy and 25 mu J/cm(2) energy flux, and sublinear at higher irradiations. This finding shows the importance of characterizing the detector response linearity for accurate THz metrology. The detectors had high sensitivity in single-pulse detection mode up to 10 kHz repetition rate. |
