This module will present (a) the fundamentals of generation of laser pulses; (b) the techniques to pulse shorten and measure laser pulse duration; and (c) the of pulsed laser devices as well as their applications. The module will start with the most famous techniques of laser pulses generation: Q-Switching and Mode Locking. Pulse shortening techniques will follow. Continuously measurement methodologies using the Kerr Effect, Prisms, DBR Mirrors and Interferometry will be presented.
The final part will contain various pulsed laser systems we use in nanotechnology laboratories. Closing a number of applications of pulsed laser devices will be presented on areas like telemetry, communications, spectroscopy, medicine, digital media (CD, DVD).
