Abstract

This paper demonstrates the characteristics of the THz parametric frequency upconversion detection based on the stimulated polariton scattering in KTiOAsO₄ (KTA) crystal pumped by a 1064 nm pulsed laser (420 ps, 1 Hz). The detectable spectral ranges can be from 3.54 to 4.03 THz, from 4.08 to 4.50 THz, from 4.71 to 5.16 THz, and from 5.87 to 6.32 THz. The minimum detectable energy is 0.24 fJ at 4.92 THz with a dynamic range of 57 dB.
