Mid-infrared ultrafast and nonlinear spectroscopy of semiconductors

摘要

This paper describes our recent experiments using 140 fs pulses of intense, coherent, and tunable midinfrared (MIR) radiation produced by an optical parametric amplifier. These experiments explored MIR ultrafast and nonlinear optical phenomena in bulk semiconductors, InMnAs/GaSb ferromagnetic heterostructures, and single-wall carbon nanotubes.
