Content:

Introduction.
Ultrashort laser pulses, linear and nonlinear propagation.
Dispersion compensation, pulse shaping, ultrashort pulse characterization.
Ultrafast lasers, principles of femtosecond pulse generation, mode-locking.
Introduction to ultrafast phenomena in semiconductors.
Emission spectroscopy methods - photoluminescence: streak camera, ultrafast gating techniques (Kerr gate, frequency upconversion, applications)
Pump and probe techniques, (transient transmissivity/reflectivity, polarization rotation).
Introduction to coherent phenomena. Coherent time-resolved spectroscopy (photon echo, 2D coherent spectroscopy).
