R.I.P. Charles Townes, the physicist whose work touched all our lives
Townes came to fame for his pioneering work on the theory and applications of the maser , which he then followed up by designing the first laser. Lasers are used in many common consumer devices such as optical disk drives, laser printers, barcode scanners and fibre-optic cables. They are also used in medicine for laser surgery and various skin treatments, and in industry for cutting and welding materials.
The work of Charles Townes in physics has thus had an enormous impact on everyday life; he was awarded the Nobel Prize for is his work on quantum electronics, especially lasers and masers.
It’s very sad that he didn’t quite make his century, especially because this year is the International Year of Light, which will involve many activities and celebrations relating to his work on lasers. Much of our experimental work in Physics here in the Department of Physics and Astronomy at the University of Sussex involves lasers in various ways, and we will find an appropriate occasion to celebrate the life and achievements of a truly great physicist. Until then let me just express my condolences to the friends, family and colleagues of Charles Townes on the loss not only of an eminent scientist but of an extremely nice man.
