From the time of its invention, laser has always been a wonderful tool to look into matter. On the other hand, an intense laser can be used to create other extreme states of matter such as plasma, warm dense matter etc. I have been working on various aspects of high intensity laser-matter interactions for more than a decade. One of the key area of my interest is efficient generation and transport of intense laser-driven fast electrons [1-5], which is experimentally challenging and fundamentally important for the applications in laser fusion study [6], ultrafast electron microscope [7], radiobiology and radiotherapy [8] etc. On the other hand, using high intensity femtosecond lasers, we experimentally create scaled version of astrophysical objects (high-energy-density states) and study their ultrafast dynamics and associated giant magnetic fields in real-time [9]. We also discovered the THz acoustic phenomena in the hot solid density plasma for the first time [10]. Study of intense femtosecond laser driven shock dynamics in hot dense plasma is another unique feature of our research. We have figured out how to control such shockwaves [11] and therefore it may open up new possibilities to shock treatment of cancer cells [12] or to generate coherent THz radiation of tuneable frequency by launching a shockwave into a polarizable crystal [13]. In a relatively recent fundamental study, absorption of a near-relativistic intensity high contrast laser by a fused silica target is extensively explored [14]. This study is fundamentally important for the application in plasma mirror at near-relativistic intensities and in laser energy coupling for target normal sheath acceleration (TNSA) for proton acceleration. TNSA is one of the backbone to the modern proton therapy for cancer treatment [15]. Using intense femtosecond laser, we also generate coherent extreme ultraviolet (EUV) photons by high harmonic generation (HHG) process and use it in EUV nanometrology to characterize thermal and acoustic disturbance in meta-lattices at nano-scales [16,17], ultrafast carrier and structural dynamics in warm dense nano-membrane etc. These kinds of studies are of high demand in R&D sector of semiconductor industries. Furthermore, we also investigate the ultrafast nonlinear studies on high power optics [18], which is very important in laser and optics industries and also extremely important for all the studies related to high power laser matter interactions. Currently, we are also investigating on high contrast high power short-pulse laser channelling and filamentation dynamics in air. This investigation will have direct relevance in lightning control project [19].   Currently, we are also exploring multinational collaborative experimental proposal in the Joint Extreme Light Infrastructure (ELI) . Here, we should get the opportunity to use PW (10^15 W) laser beam-line of ELI Romania and study ultra-relativistic heating of electrons by localized PW lasers fields at nanostructures and its applications in bright gamma ray and high energetic particle (electrons, positrons, protons, ions) production. Especially, bright gamma-rays over 10 MeV are investigated as potential new approaches for several applications such as radio isotope production, nuclear transmutation via photon absorption at investigation of the giant resonance of the nucleus.   Very recently, I have also received the SERB SRG grant for pursuing the Study of Strongly Coupled Non-Ideal Plasma States of Carbon at Extreme Conditions. The study of strongly coupled plasma states of carbon (liquid/WDM/HDM) will not only be important for scientific curiosity but also for the relevance in modelling of both terrestrial and astrophysical systems, picosecond optoelectronic switch, and controlled manufacturing of emerging carbon nanomaterials. I have also received a FRS grant at IIT (ISM) Dhanbad to study intense laser ablation dynamics for green synthesis of nanomaterials for biomedicine, bio-imaging and environmental applications.   In future, I also wish to explore the frontier area of high harmonic generation (HHG) and its applications in (i) time resolved x-ray absorption spectroscopy for the study of ultrafast carrier and structural dynamics in solid, warm dense matter and plasma, (ii) ultrafast x-ray imaging, (iii) ultrafast magnetics and, (iv) atto-science.   Therefore, it is clearly evident that my past research, recent activities and future research outline not only probe the fundamental questions of intense laser-plasma interactions/dynamics but also have direct relevance and future scope in industries, technological advancements and social benefits. -------- Prof. Amitava Adak, Assistant Professor, Department of Physics, IIT(ISM) Dhanbad.
