microscope. Working with some theoretical calculations, he invented
the principle of holography: to record the phase of a lightwave by running
another lightwave into it. Although he even succeeded to produce some
kind of hologram (a very small one), to make it work properly there was
one thing still missing: the right lightsource.
To make a hologram you need coherent light; this is light in
