Research Proposal Kanaka Raju Pandiri Kansas State University, USA Recent progress in ultrafast lasers gained a lot of interest to investigate ever faster physical processes in atoms, molecules, and solid state surfaces. This advancement gave birth to a broad field of science crossing physics, chemistry, and biology; known as “Ultrafast Science” for which Zewail got the Nobel prize in 1999. But, following electron dynamics in real time, watching the formation or breaking of chemical bonds, or the

Introduction The words biophotonics is a mix of science and photonics. As the expression demonstrates the science and innovation utilization and recognition of photons (a quantum of electromagnetic radiation or rudimentary molecule that is its own antiparticle), and lights quantum units. Photonics is essentially interrelated with gadgets it mean is the limb of physical science that arrangements with the discharge and impacts of electrons and with the utilization of electronic gadgets. Biophotonics

of a ruby laser beam via a quartz crystal by Franken et al,1 borate materials have been widely studied to employ in the potential applications such as nonlinear optics (NLO) and laser (mainly in visible and UV light) engineering.2, 3, 4, 5 Materials with NLO properties are useful for generating new frequency laser sources that cannot be directly produced from the common laser sources.2 Consequently, NLO materials have enabled a wider range of frequencies produced from the available laser. Borate materials

This article describes the interaction of a laser pulse train on napthalocyanine and phthalocyanine systems, in order to analyze their behavior in terms of optical limiting by tuning the laser parameters. The main conclusion of the work is that the single sub-pulse duration is the most important parameter that affects the optical limiting process. The topic of the manuscript, may be of interest to the audience of the Journal of Computational and Theoretical Chemistry. However, the computational methodology

The produced net charge can be detected by ammeter connected to the two electrodes. This photoinduced current signal inside the nanocircuit is following the driver laser field instantaneously3-5. Therefore, it can be controlled by tailoring the driving electric field1,2. Experimental approach: Light field synthesis. The PI is very capable to lead this project to the ultimate success. He engineered and developed the

Gordon Gould proposed laser action, then not long after 4 years, in 1960, first laser was build by Theodore Maiman. Besides that, Gordon also derived the word laser from “light amplification by the stimulated emission of radiation”. The laser developer look amplification is very important as a step to build a laser, so these people make one advance to develop amplifiers from semiconductor laser to be used as light sources. This is because of semiconductor have high gain. Laser made up with high gain

The potential for light to perform work is called light energy. (Light Energy Facts. (n.d.)). Light energy is the only form of energy that we can actually see directly. (Light Energy Facts. (n.d.)). It is formed through chemical, radiation, and mechanical means. (Light Energy Facts. (n.d.)). Light energy can also be converted into other forms of energy. (Light Energy Facts. (n.d.)). Light consists of photons, which are essentially tiny packets of energy. (Light Energy Facts. (n.d.)). When an object's

Lasers A laser is a gadget that transmits light through a procedure of optical intensification in view of the fortified outflow of electromagnetic radiation. The expression "laser" began as an acronym for "light enhancement by animated emanation of radiation". The first laser was implicit 1960 by Theodore H. Mailman at Hughes Laboratories, taking into account hypothetical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser varies from different wellsprings of light in that it emanates

like handset” that can pick sounds from amplifiers under the floor. At the entrance, a tunnel descends into a clam-shaped room which was dark and lit only by mobile patterns of laser light. People first entered the pavilion through the Clam Room, met by a laser deflection system which projected colors from a krypton laser. Lowell Cross designed the psychedelic system which introduced visitors to the multimedia aspect of the Pavilion. In its conception, Robert Whitman
