Abstract

A terahertz wave generation device includes a light source device emitting an optical pulse, and an antenna generating a terahertz wave through irradiation of the optical pulse that is emitted from the light source device onto the antenna, wherein the light source device includes an optical pulse generation unit generating the optical pulse, a first pulse compression unit performing pulse compression based on saturable absorbers with respect to the optical pulse generated by the optical pulse generation unit, a second pulse compression unit performing pulse compression based on group velocity dispersion compensation with respect to the optical pulse already compressed by the first pulse compression unit, and an amplifying unit installed between the first pulse compression unit and the second pulse compression unit to amplify the optical pulse emitted from the first pulse compression unit.
