Crystals and Lasers: The Micro-world (1987x1)

:

A visit to the extraordinary micro-world of crystals and lasers where atoms are only l/10,000th of a millionth of a metre apart, and laser light pulses only l/100th of one millionth of one millionth of a second. In their first lecture, John Meurig Thomas and David Phillips examine the symmetry and other striking physical characteristics of minerals and gemstones.
