Modified window function for optically thick samples measured by a terahertz time-domain spectroscopic system using a multimode laser diode

Morikawa, Osamu; Hamada, Dai; Ozturk, Turgut; Yamamoto, Kohji; Kurihara, Kazuyoshi; Kuwashima, Fumiyoshi; Tani, Masahiko (The Optical Society, 2021)

A low-cost type terahertz time-domain spectroscopic system can be constituted using a multimode laser diode instead of a pulse laser. To suppress noise, a window function is usually used in the Fourier transformation. When ...
