About the Lab
Established in 2004, the Femtosecond Laser Lab at the Indian Institute of Technology Kanpur focuses on theoretical and experimental laser-based optical approaches to coherent control of molecular dynamics. Our research spans quantum computing, biological imaging, femtosecond chemistry, control dynamics, measurement, information theory, and cognition.
We investigate ultrafast laser pulse shaping applications in gaseous and liquid phase molecular dynamics, opto-electronics, biologically relevant multi-photon fluorescence microscopy, optical trapping, and quantum computing.
What We Do
- Pulse shaping
- Develop novel experimental techniques
- Probe system dynamics
- Investigate quantum communication techniques
- Understand colloidal aggregation
- Uncover new processes via non-linear techniques
