High-power terahertz pulse generation and application to nonlinear spectroscopy

Kōichiro Tanaka

Open publisher page 0 citations

Abstract

We have recently developed novel generation methods of intense terahertz single cycle pulses that is called as the Cherenkov scheme with tilted wave-front technique in the LiNbO3crystal. The maximum electric field becomes larger than 1 MV/cm, which enables us to perform nonlinear terahertz spectroscopy in solids. Several examples in semiconductors and grapheme clearly show the intense terahertz pulse can induce strong nonlinear effects in wide frequency range.
