Lifetimes for the LH1 to HH1 transition in GaAs/AlGaAs quantum wells are measured by pump and probe spectroscopy using a free electron laser. The energy of the LH1 to HH1 transition is below that of the longitudinal optical phonon. A value of 55 ps is found for a 67 Å wide well at 8 K. Comparisons with recent measurements for electron systems are presented.
