Femtosecond

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

Topic: LASIK eye surgery Organizational Pattern: Categorical General Purpose: To inform Specific Purpose: To inform the audience about LASIK eye surgery Introduction: I. Attention getting device: Vision is one of our most used senses; in the world today many people struggle with this sense. Today I’m going to be talking about a way to help improve this sense for many people; I’m going to be talking about LASIK eye surgery. II. Relevance: Almost everyone in this room knows someone who has thought

4.1 GENERAL CONSIDERATIONS FOR POST-KERATOPLASTY REFRACTIVE SURGERY The corneal graft-host junction typically heals by 1 year after transplantation and corneal surface stability is achieved from 3 to 4 months after complete suture removal. However, this period can significantly vary due to patient's age, general health status (diabetes mellitus and collagen vascular disorders) and use of topical and systemic immunosuppressive medications. Given that, any surgical intervention for post-PKP astigmatism

In the past, the applications of light, more specifically laser, in health and clinical applications have been focused on its destructive phototoxic effects. This effect is associated with high energy radiation, whereas low energy radiation has been found to induce a stimulating effect on the cells. The heat inducing laser tissue ablation effect used in surgery and the disinfectant-antimicrobial effect of light therapy are distinctly different from the beneficial healing response stimulated by photobiomodulation

CHAPTER 1: INTRODUCTION Various cementitious composites are extensively used in construction industry. Their properties vary in a large scale and incorporation of desirable properties in cementitious composites has been an active area of interest for research. Such a study not only helps to attain higher efficient materials but also helps to improve upon already existing ones. Identifying and modeling the atomistic structure and simulating the material response are hence relevant and futuristic.

Running Head: SURVIVAL AND SCIENCE Nature Articles Name of Student School Introduction The unprecedented upheavals in the environment in the last few decades cannot escape anyone's notice. Widespread and increasing global pollution, natural disasters of unusual intensities in more and more places, new and deadlier diseases, disappearance of animal and plant species, and disturbing signs even in the skies are among these. Seven serious observers publish respective opinions on the nature of these

Terahertz (THz) waves, or T-rays, refer to electromagnetic radiation in the frequency range of 0.1–10 THz. THz waves occupy the region between microwaves and the infrared, as shown in Figure 1.1. Until about two decades ago, when THz time-domain spectroscopy technique was invented, the THz spectrum had remained more or less unexplored and unutilized. However, the development of ultrafast lasers and derivative techniques such as photocon¬ductive switching and sampling and electro-optic generation
