U3A talk on lasers

akkreditasie

When the laser was developed some 60 years ago it was euphemistically described as “a solution looking for a problem”.

Today the laser is an essential technology of the 21st century and a multibillion-dollar industry which impacts almost every aspect of our daily life. While we often to refer to some laser treatment, procedure or process, do we really know what it involves?

On Wednesday 4 August, Professor Hubertus von Bergmann will share his enormous knowledge of lasers with members of U3A Helderberg via a live-stream presentation at 10:00.

The Somerset West resident will touch on the history of laser technology, explain how it works and how laser light differs from that of conventional light sources. He will also discuss the different types of lasers and some of their most important applications ranging from industrial materials processing, medical diagnostics and treatments, environmental management, communications technology to the military. Finally, he will mention some major technological laser breakthroughs on the verge of realisation in the fields of cancer treatment, alternative energy, and much more efficient and faster computers and communications.

Originally from Germany, Von Bergmann immigrated to South Africa in 1973. Since then he has been associated with the University of Natal (PhD in Laser Physics in 1980) and has held various positions at the National Physical Research Laboratory of the CSIR in Pretoria, the Systems Laboratory of the Rand Afrikaans University, and the Molecular Laser Isotope Separation programme at the Atomic Energy Corporation of South Africa. In 2000 he joined the Department of Physics at Stellenbosch University. Since retiring in 2007, he has continued with his research, which now spans more than 50 years. He currently consults for PAR Systems and is Professor Emeritus at the Laser Research Institute of Stellenbosch University.

He holds 20 patents related to laser technology and has published over 100 papers.
