It is well known that nonequilibrium populations of phonons can be generated in bulk semiconductors by the relaxation of photoexcited hot electrons. In this paper we demonstrate that nonequilibrium phonons can also be generated in quantum wells by picosecond lasers and then probed by time-resolved R
