Punjab Study

Lahore: 09 Feb: Lahore University of Management Sciences (LUMS) Lahore has announced that Decomposition of white light into its spectral components was first studied by Newton. Three centuries since this revolutionary discovery, ultrashort laser pulses and nonlinear optics have made it possible to produce artificial white light with controlled time duration.
At the Department of Physics, Dr. Tayyab Imran's recent work has demonstrated the generation of an intense beam of broad spectrum light. The supercontinuum is achieved by pumping an ultra-fast laser beam into sapphire crystal. The resulting spectrum extends from the blue visible to the near infrared and is exceptionally clean, promising interesting applications in the areas of optical communications, fluorescence microscopy and gas sensing.
Dr. Imran’s research has been published in the Journal of Optics [Tayyab Imran and Gonçalo Figueira, J. Opt., 14, 035201 (2012).
The Department of Physics, under Dr. Tayyab’s leadership, is starting a research focus area on laser engineering. Recently, the National Institute of Lasers and Optics(NILOP), Islamabad has lent a high-power nitrogen laser to the Department. The 150 kW ultra-violet emission in pulsed mode with lengths of the order of 10 ns, will open up new explorations in the probing of dynamical chemical, biological and physical processes.
