Image of FIG. 1.
FIG. 1.

Experimental setup for room-temperature detection of monochromatic terahertz wave pulses. The inset refers to the SWPF.

Image of FIG. 2.
FIG. 2.

(a) shows the measured temporal profiles of the output upconverted signal at different incident terahertz wave intensities. The inset shows the bolometer measurements of the terahertz wave radiation prior to entering the LN detection crystal. The and annotations refer to measurements of the temporal profiles of THz-wave radiation and the up-converted signal by inserting terahertz wave attenuators of 10% or 1% transmittance, respectively. (b) is a partial vertical extension of (a).

Image of FIG. 3.
FIG. 3.

Shows the upconverted signal energy as a function of the temporal profile peak voltage of the terahertz wave measured by the Si bolometer. The linear least-square fit to the data is given by the straight line.
