2. The first working prototype of a laser. Theodere Maiman builds the firs working prototype of laser at Hughes Research Laboratories in Malibu, California. This laser uses synthetic ruby as the active medium and emits a deep green beam of coherent light.

3. The Spectroscopy. Modern laser sources produce monochromatic light with virtually any wavelength. The high energy stored in these pulses can be focused on the researching sample a spot comparable in size to the wavelength, which makes it possible to investigate nonlinear optical effects.
