His work has built upon a history of over thirty years of working on pulsed laser experiments and has established other milestones in the field. He developed the self-calibrated femtosecond optical tweezers method for reproducible pulsed laser optical tweezers experiments with an additional forced oscillatory mode of motion. He went on to use the femtosecond optical tweezers to provide a direct measure and control of 'in situ' temperature and viscosity at micro-scale volumes.<ref>{{Cite journal|last1=Mondal|first1=Dipankar|last2=Mathur|first2=Paresh|last3=Goswami|first3=Debabrata|date=2016|title=Precise control and measurement of solid–liquid interfacial temperature and viscosity using dual-beam femtosecond optical tweezers in the condensed phase|journal=Physical Chemistry Chemical Physics|volume=18|issue=37|pages=25823–25830|doi=10.1039/c6cp03093a|pmid=27523570|bibcode=2016PCCP...1825823M|issn=1463-9076|doi-access=free}}</ref> He used this method to directly detect colloidal assembly, their structure, and orientation,<ref>{{Cite journal|last1=Mondal|first1=Dipankar|last2=Bandyopadhyay|first2=Soumendra Nath|last3=Goswami|first3=Debabrata|date=2019-10-31|title=Elucidating optical field directed hierarchical self-assembly of homogenous versus heterogeneous nanoclusters with femtosecond optical tweezers|journal=PLOS ONE|volume=14|issue=10|article-number=e0223688|doi=10.1371/journal.pone.0223688|pmid=31671114|pmc=6822744|bibcode=2019PLoSO..1423688M|issn=1932-6203|doi-access=free }}</ref><ref>{{Cite journal|last1=Mondal|first1=Dipankar|last2=Goswami|first2=Debabrata|date=2016-10-07|title=Controlling and tracking of colloidal nanostructures through two-photon fluorescence|journal=Methods and Applications in Fluorescence|volume=4|issue=4|article-number=044004|doi=10.1088/2050-6120/4/4/044004|pmid=28192297|bibcode=2016MApFl...4d4004M|s2cid=23967019 |issn=2050-6120}}</ref> which affirmed the spatiotemporal aspects of the method.

Breaking the barrier of programmable pulsed laser generation has been concomitant to his insights into the theoretical aspects of pulsed light and heat dissipation dynamics. His work on the cumulative thermal effects of femtosecond infrared lasers, has revolutionized the existing framework of laser heat dissipation.<ref>{{Cite journal|last1=Singhal|first1=Sumit|last2=Goswami|first2=Debabrata|date=2020|title=Unraveling the molecular dependence of femtosecond laser-induced thermal lens spectroscopy in fluids|journal=The Analyst|volume=145|issue=3|pages=929–938|doi=10.1039/c9an01082c|pmid=31820745|bibcode=2020Ana...145..929S|s2cid=209166478 |issn=0003-2654}}</ref> This has in turn been shown to be the key to mitigating the deleterious effect of heat accumulation during sensitive measurements of nonlinear optical properties.<ref>{{Cite journal|last1=Singhal|first1=Sumit|last2=Dinda|first2=Sirshendu|last3=Goswami|first3=Debabrata|date=2017-01-19|title=Measurement of pure optical nonlinearity in carbon disulfide with a high-repetition-rate femtosecond laser|journal=Applied Optics|volume=56|issue=3|pages=644–648|doi=10.1364/ao.56.000644|pmid=28157924|bibcode=2017ApOpt..56..644S|issn=0003-6935}}</ref> Further, this led to the first demonstration of the hitherto unexplored distinction between molecular structures with femtosecond laser-induced thermal spectroscopy.<ref>{{Cite journal|last1=Kumar|first1=Pardeep|last2=Goswami|first2=Debabrata|date=2014-12-03|title=Importance of Molecular Structure on the Thermophoresis of Binary Mixtures|journal=The Journal of Physical Chemistry B|volume=118|issue=51|pages=14852–9|doi=10.1021/jp5079604|pmid=25418934|issn=1520-6106}}</ref> Femtosecond thermal spectroscopy with infrared lasers has thus become a new spectroscopic identification method.

In more direct applications of the experimental framework driving his work, he has demonstrated how to distinguish overlapping fluorophores in multi-photon imaging microscopy using near-IR high repetition rate femtosecond lasers by exploiting repeated excitation and de-excitation processes that help to distinguish and eventually eliminate abnormal cells from healthy ones.<ref>{{Cite journal|last1=Goswami|first1=Debabrata|last2=Das|first2=Dhiman|last3=Nath Bandyopadhyay|first3=Soumendra|date=2015|title=Resolution enhancement through microscopic spatiotemporal control|journal=Faraday Discussions|volume=177|pages=203–212|doi=10.1039/c4fd00177j|pmid=25623778|bibcode=2015FaDi..177..203G|issn=1359-6640}}</ref><ref>{{Cite journal|last1=Kumar De|first1=Arijit|last2=Roy|first2=Debjit|last3=Goswami|first3=Debabrata|title=Selective two-photon fluorescence suppression by ultrafast pulse-pair excitation: Control by selective one-color stimulated emission |journal=Journal of Biomedical Optics |date=2011 |volume=16|issue=10|pages=100505–100505–3|doi=10.1117/1.3645082|pmid=22029344|pmc=3684794|bibcode=2011JBO....16j0505K|issn=1083-3668}}</ref>
