oa CSIR Science Scope - Porro-prism laser enigma unravelled through mathematical optics : mathematical modelling

Volume 2, Issue 4
  • ISSN :



An enigma for 30 years, a problem in Porro-prism lasers has now been solved by CSIR researchers by applying basic arguments of mathematical symmetry, together with new physical insight into intra-cavity Porro prisms. The mathematical optics team at the CSIR National Laser Centre concentrates on solving problems in the realms of optics and lasers by approaching problems with mathematical rigour, while recognising the importance of experimental verification. Topics currently studied include creating novel laser beams for biological trapping and tweezing (the technique of using a focused laser beam as an atom trap), propagation of laser beams through a turbulent atmosphere to improve telecommunications signals and creating new laser systems based on micro-optical elements.
