Ultra-fast laser

A team of researchers from the University of Colorado discovers a new way to use laser light. Two very short pulse lasers must be used; when the two lasers are synchronized, the obtained laser beam has the characteristics of both.

In this way pulses of ultraviolet light can be obtained that cannot be achieved with a single laser. These fast lasers act in a similar way to strobe lamps and allow to “freeze” the movements of different processes that occur in molecules and atoms.
