KISS-DU Organizes Invited Lecture on ‘Science and Technology of Non-Linear Optical Absorption’


The Nano Innovation Laboratory, School of Indigenous Knowledge, Science and Technology (IKST), KISS-DU, organized a Distinguished Invited Lecture on ‘Science and Technology of Non-Linear Optical Absorption’ on18th July 2022. Dr. Balaram Sahoo, Indian Institute of Science (IISc) Bangalore delivered the lecture.

Professor Deepak Kumar Behera, Vice-Chancellor, KISS-DU, in his welcome address, shared the progress made by the Nano Innovation Laboratory at KISS-DU. The Lab has played a key role in connecting scientists all over the world. He threw light on the different research collaborations done by Nano Innovation Lab and also about the research advisory committee of the Laboratory. He expressed his happiness to announce that Dr. Balaram Sahoo, IISc .Bangalore has consented to be one of the advisors at the Nano Innovation Laboratory, KISS-DU.

Dr. Balaram Sahoo, in his lecture, explained the fundamental concepts of light and focused on laser based devices. The exposure to the high intensity laser has many hazardous effects on human health. Hence, laser safety is considered to be very important nationally and internationally.  Laser shields, at present, are based on highly absorbing nonlinear optical materials. Absorption of laser beams in these materials is related to various nonlinear inelastic processes such as multi-photon absorption. He also described about different materials used for laser safety application.

Speaking on the occasion, Dr. S.K.S. Parashar, Associate Professor, KIIT-DU explained the physics of light and urged the research scholars to inculcate the skills required to be a good researcher. The programme was coordinated by Dr. Bikram Keshari Das and Dr. Tanushree Das, Chemistry Programme, School of IKST, KISS-DU. It ended with a vote of thanks by Dr. Yasobanta Das, Dean, School of IKST, KISS-DU.
