A critical analysis highlighting the most innovative contributions of the nominee that have made a difference (If necessary, attach additional sheets). ________________________________________________________________________ It has been a passion of the nominee (Dr. D. Goswami) to exert light-induced control through laser-matter interaction and explore their applications. His work on the development of acousto-optic modulated (AOM) femtosecond pulse shaping has made him one of the leaders in pulse shaping technology (Phys. Rep. 374, 385(2003)). During the last five years, he has made significant, original contributions in the field of femtosecond laser applications to selective photodissociation, microscopy and bio-photonics, and in exploring optical approaches to quantum computation. Femtosecond Laser Pulse Shaping Technology Dr. Goswami has constructed several versions of tunable and programmable femtosecond pulse shaper in his laboratory (Nature NewsIndia, Dec. 2003; Curr. Sc. 92, 1346 (2007)). He has developed high-fineness measurement approaches not only to characterize such complex pulses but also to report some highly sensitive experimental measurements (Opt. Comm. 261, 158 (2006)). High-finesse experimentation has been one of the major hallmarks of his experimental dexterity. The experimental developments in pulse shaping have also led to optical coding and transmission, which is summarised in his United States Patent 20040208613 (2004). Most recently, Dr. Goswami has also developed time resolved three-pulse photon-echo spectroscopy (or 2D spectroscopy) to determine ultrafast dephasing lifetimes in porphyrins (Chem. Phys. Lett. 476, 31 (2009)). Control with intense lasers and with laser polarization Dr. Goswami has evolved laser polarization control schemes for highly nonlinear processes such as supercontinuum generation (Phys. Lett. A 341, 523 (2005)). Such has been the impact of this particular aspect of supercontinuum work that it was also included through invitation in the special issue of Applied Physics B 77. This control aspect with polarization for highly nonlinear process was unravelled due to the extremely high signal to noise achieved in these experiments. Presently polarization based control has also been demonstrated for two-photon processes (PhD Thesis, A. Nag). Dr. Goswami has also shown selective molecular photofragmentation with Frequency chirped intense laser pulses under supersonic beam conditions (Chem. Phys. 96, 1496 (2009); Best poster National Laser Symposium-2009). Ultrafast Pulse Shaping Approaches to Adiabatic Quantum Computing Dr. Goswami was the first to propose how the phase of a laser pulse can be critical in Quantum Computing (PRL 88, 177901 (2002)) and the experimental approaches to adiabatic quantum computing (J. Phys. A 38, L615 (2005)) in analogy to the coherent control approaches (JCP 127, 124305 (2007)). However, being pragmatic, Dr. Goswami has been keen on the present perspective of the problem and implementation issues for all possible alternate forms of computing and with this view he also organized a successful International conference with support from several International sources that include Indo-US, Max-Planck and ICTP on Quantum Computing: Back Action 2006 at IIT Kanpur. The AIP Press has come out with a Refereed Volume (AIP Conf. Vol. 864 (2006)) for the same with Dr. Goswami as the Editor, which has also received rave reviews (Curr. Sc. 94, 392 (2008)). Coherent Control applications to Microscopy Dr. Goswami’s strong theoretical dexterity enabled him to recognize that simple connection could exist in several experimental femtosecond laser conditions between single- and multi-photon processes (PRA 64, 033410 (2001)) which he has utilized with ultra-sensitive designed experiments with high-repetition low-average power femtosecond laser pulses for microscopy (SPIE 7183, 71832B (2009).). A significant and exciting result is also that femtosecond pulse shaping experiments on multi-photon processes in terms of the laser phase modulation can also drastically impact the two-photon absorption. Such a result has strong implication for imaging applications and the institute has filed a patent application (patent filed, Mar.’08). Biomedical Applications Dr. Goswami’s efforts in pulse shaping applications to biomedical research were first recognized and appreciated through the International Senior Research Fellowship from the Wellcome Trust (UK). As part of this project he has been developing a pulse shaping enhanced multi-photon imaging technology for better diagnostic and depth-profiling (J. Micros. 233, 320 (2009)). This enhanced imaging instrument is expected to be useful in the early diagnosis of cancerous cells. Similarly, its capability to deliver higher laser dosage would be used for photodynamic therapy. Dr. Goswami has also developed a high-tech pulsed laser optical tweezers in his laboratory (Curr. Sci. 95, 723 (2008)) that has resulted in a more stable three-dimensional (3D) optical trap holding latex nanoparticles which is otherwise not possible with continuous wave (CW) lasers at the same power level (Best Paper Award at Photonics-2008). Dr. Goswami works in the forefront of reaction dynamics, developing pulse shaping techniques for controlling chemical dynamics. He has gone about implementing them using femtosecond laser pulses. He has been a champion of various instrumentation techniques and has developed the necessary photo-acoustic pulsed laser techniques and built a sophisticated laboratory from scratch. He has demonstrated the utility of multi-photon absorption techniques and has developed novel multi-photon imaging techniques and optical tweezers, which have applications in distinguishing and eliminating abnormal cells from healthy (normal) cells. He has made fundamental contributions to the basic understanding of the control of molecular systems. Application of phase modulated laser pulses as generated by Dr. Goswami has shown advantages in information processing, transport across interfaces and in high resolution spectroscopy. A new dimension of bioimaging is on way due to these technological developments.
