  • We used a new dual wavelength solid state laser system with an extrawide tunability (3 - 19 micrometer) in ps pulses for the study of 'intersubband' resonances in two-dimensional semiconductors, multiple quantum wells, -- using absorption saturation, hole-burning and nondegenerate four-wave mixing spectroscopies. New data on the excited state electron lifetimes and line-broadening mechanism were obtained for different quantum wells widths and compositions.
