A laser invented in Scotland is so
small that it can fit into a matchbox.
Developed by Bruce Sinclair and
Neil Mackinnon of the School of
Physics and Astronomy at St
Andrews University, the laser is
simple to mass-produce and its spe
cial construction allows it to generate a high-quality green beam over a
long and efficient life span.
The power source is a diode las-e-similar to the one used in compact disc players. The laser is poered by a beam that is reflected through a crystal that converts its infrared light into green laser light.
