Established in the year 2004 the Femtosecond Laser Lab at the Indian Institute of Technology, Kanpur primarily focuses on theoretical and experimental laser-based optical approaches of coherent control of molecular dynamics leading to vast applications ranging from quantum computing to biological-imaging. We work at the frontiers of multiple disciples, including femtosecond chemistry, control dynamics, measurement, information theory, electrical engineering and cognition. More specifically, we are investigating ultrafast laser pulse shaping applications in gaseous and liquid phase molecular dynamics, opto-electronics, biologically relevant multi-photon fluorescence microscopy & optical trapping and knotting all these odd ends together leading to quantum computing.

What We Do

  • Pulse shaping
  • Develop novel expermental tecniques
  • Probe system dynamics
  • Investigate quantum communication techniques
  • Understand colloidal aggregation
  • Uncover new processes via non-linear techniques
