title: High-resolution nonlinear laser spectroscopy of room-temperature GaAs quantum-well structures: observation of interference effects.
abstract: We describe frequency-domain four-wave mixing spectroscopy measurements near the fundamental band edge in room-temperature GaAs multiple quantum wells. The line-shape information gives a measure of the dynamical behavior of the material and what is to our knowledge the first observation of an interference line shape due to a dominant slow contribution to the nonlinear response.
