9.5.3 Lasers which emit very short pulses (10-15-10-18 [sec]).
Very short pulses are a new tool for research.
Applications of very short pulses:
They can be used to study rapid processes. Illuminating the process at short intervals, and taking a picture.
Optical communications. The shorter the pulse, the greater the number of pulses that can be send in a second. This number determine the amount of information that can be transmitted in a given time.
