Evolution of the laser
The evolution of the laser is not some recent or overnight event. It was Albert Einstein who first laid out the theoretical groundwork for the creation of the laser in his work ‘On the Quantum Theory of Radiation’ nearly a century ago in 1917. It was only in 1960, after the work of many physicists and engineers in between, that Theodore Maiman put on show the first actual working laser.
Over the years that followed this first demonstration, various competitors fought to create and patent their own versions of the technology, each one using different methods and with different ideas of their potential uses. Now there are many different types available throughout the world, created to do different things in different ways.
For instance there are lasers used for surgery, used as a way of operating bloodlessly as each incision is cauterised as the cutting happens. These lasers help people in the curing or alleviating of many conditions from life threatening ones to minor ones and everything in between. Lasers are even employed to perform delicate operations in infertility treatments such as IVF.
The cosmetic sector has uses for lasers as well, particularly for getting rid of things which are unwanted, such as laser hair removal and the use of laser scalpels in surgeries like liposuction where patients may particularly want a reduced healing time. They are also used in getting rid of unwanted additions people may have made to their own bodies, such as in tattoo removal.
