Ultrafast Lasers and Optical Amplifiers
Physics department, IIT Madras, Chennai 600 036, India



We are a small research group focused on Time-domain Photophysics and Nonlinear Optics & Spectroscopy at IIT Madras (Chennai, Tamilnadu, South India). The emphasis is on imparting students the experimental skills that generally go parallel to the black-box, push-button technology. Along with the ‘fabrication-development’ activity, students also use it for studies of various phenomena with steady state and time-resolved spectroscopy.
