Abstract :
A high-sensitivity, fast-response THz-wave detection using an organic nonlinear optical crystal of DAST has been demonstrated. In this report, the optimum performance of THz-wave detection was investigated in parameters such as the thickness of DAST, pump wavelength, and pumping intensity. Consequently, a higher sensitivity was obtained.
