themselves as a legitimate way to move energy wirelessly, and it is a technology still being developed today. The applications of microwaves I will discuss later. Laser beams have been used as a means for transmitting energy wirelessly since 1960. A laser beam system would work in a similar method as a microwave unit would. Laser beams are still being developed as a viable option for wireless electricity. Only recently has been the

Introduction Free Space Optics is an advance technology used to transmit data from one point to another using light a medium. This technology has emerged in 1960’s and has been advanced day by day. This has become the advanced and mostly used because of the data rates and the bandwidths provided by this type of communication. This is now mostly used for connecting different LANs and also used in satellite communication. There are many wireless technologies like Bluetooth, infrared and many others

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

techniques exist to accelerate tooth movement and thereby shorten treatment time ( ). Recently, a non-invasive form of therapy has emerged: low-level laser therapy (LLLT). LLLT uses low-level lasers to produce photochemical and non-thermal biological effects ( ). A more recent and appropriate term for LLLT is photobiomodulation (PBM), a term that includes non-laser light sources, and alludes to the physiologic nature of the therapy. PBM has been extensively studied in medicine for wound healing, retinoprotection
