This equipment grant will be used for construction of a colliding pulse         modelocked (CPM) dye laser system, consisting of an oscillator and              amplifier.  This apparatus which can generate pulses shorter than 100           femtoseconds will enable the PIs to study the fundamental electronic            processes that allow or limit subpicosecond operation, and to develop           and test new concepts in ultrafast electronics.  The momentum and               energy relaxation time of hot carriers in semiconductors is a critical          parameter in physics and for devices.  The relaxation time is usually           not very well known but it is thought to be between &lt;100fs and 10ps.            The various relaxation process in quantum wells and amorphous                   semiconductors will be directly measured under a variety of conditions          (doping, injected carrier density, lattice temperature).  These results         will be combined with those of ongoing experimental and theoretical             effort.  The propagation of ultrashort electrical pulses will also be           used in a study of transient transport, including velocity overshoot,           in semiconductors.  The electrical output of a quantum well optical             detector will be studied with the help of femtosecond pulses.
