Last year is the 50th anniversary of the laser and we are experiencing a revolution in one of the most important aspects of laser technology. During the past decade the minimum pulse duration of optical pulses that can be generated has fallen by a factor of 40 -- from 5 femtoseconds (5x10-15 sec) to 80 attoseconds and it will continue to fall. An attoseconds or 1/1000,000,000,000,000,000 of a second is an incredibly brief time. This very brief flash is made by using laser light to control an atoms electrons and it is possible to “photograph” a molecule’s electrons and the position of its atoms with the flash. We are on the verge of making movies of bonds breaking and atoms rearranging during a chemical reaction – the very essence of Chemistry.
