Abstract :
Our recent experiments using 140 fs pulses of intense, coherent, and tunable mid-infrared (MIR) radiation produced by an optical parametric amplifier are described. These experiments explored MIR ultrafast and nonlinear optical phenomena in bulk semiconductors, InMnAs/GaSb ferromagnetic heterostructures, and single-wall carbon nanotubes.
