Ultrafast Laser Laboratory

The Ultrafast Laser Laboratory houses laser systems which emit intense light pulses with ultrashort duration of less than 100 femtoseconds (1 femtosecond is 10-15 seconds).

A pair of parametric amplifiers simultaneously generates two light pulses which are independently tunable from the ultraviolet to the mid-infrared. These light pulses are used to study the dynamical and nonlinear properties of materials and devices. Projects include turn-on dynamics in semiconductor lasers, electron spin lifetimes in semiconductors, and nonlinear optical properties of carbon nanotubes, as well as laser patterning of materials and nonlinear microscopy of quantum dots.
