Research Overview
Description and Topics
The Femtosecond Laser Lab pursues research at the intersection of ultrafast laser science, quantum information, and molecular dynamics under the direction of Prof. Debabrata Goswami.
The lab’s research spans several interconnected areas:
- Coherent control and quantum computing – using shaped femtosecond laser pulses to control molecular dynamics and implement quantum logic operations through optical approaches to qubits
- Spatiotemporal control – combining femtosecond optical tweezers with pulse shaping for simultaneous spatial and temporal manipulation of molecules and colloidal particles
- Thermal lens spectroscopy – photothermal techniques for molecular recognition, quality assessment, and nanoscale temperature sensing
- Two-photon spectroscopy and microscopy – nonlinear optical methods for studying molecular dynamics in solids, liquids, gases, and at interfaces
These areas connect through the fundamental physics of light-matter interaction at ultrafast timescales. The pulse shaper acts as a bridge, converting between time and frequency domains for both spectroscopy and control.
