  • PG0308 Pulsed Dye Laser Therapy for Cutaneous Vascular Lesions
    Pulsed Dye Laser Therapy for Cutaneous Vascular Lesions Policy Number: PG0308 ADVANTAGE | ELITE | HMO Last Review: 09/22/2017 INDIVIDUAL MARKETPLACE | PROMEDICA MEDICARE PLAN | PPO GUIDELINES This policy does not certify benefits or authorization of benefits, which is designated by each individual policyholder contract. Paramount applies coding edits to all medical claims through coding logic software to evaluate the accuracy and adherence to accepted national standards. This guideline is solely for explaining correct procedure reporting and does not imply coverage and reimbursement. SCOPE X Professional _ Facility DESCRIPTION Port-wine stains (PWS) are a type of vascular lesion involving the superficial capillaries of the skin. At birth, the lesions typically appear as flat, faint, pink macules. With increasing age, they darken and become raised, red-to- purple nodules and papules in adults. Congenital hemangiomas are benign tumors of the vascular endothelium that appear at or shortly after birth. Hemangiomas are characterized by rapid proliferation in infancy and a period of slow involution that can last for several years. Complete regression occurs in approximately 50% of children by 5 years of age and 90% of children by 9 years of age. The goals of pulsed dye laser (PDL) therapy for cutaneous vascular lesions, specifically PWS lesions and hemangiomas, are to remove, lighten, reduce in size, or cause regression of the lesions to relieve symptoms, to alleviate or prevent medical or psychological complications, and to improve cosmetic appearance. This is accomplished by the preferential absorption of PDL energy by the hemoglobin within these vascular lesions, which causes their thermal destruction while sparing the surrounding normal tissues.

  • Microfluidic Droplet Dye Laser Based on a Fabry-Perot Cavity G
    MICROFLUIDIC DROPLET DYE LASER BASED ON A FABRY-PEROT CAVITY G. Aubry1,2,3, Q. Kou1,2*, C. Wang1,2, S. Meance1,2,3, J. J. He4 and A. M. Haghiri-Gosnet3 1Univ. Paris-Sud, FRANCE 2CNRS, Institut des Sciences Moléculaires d’Orsay, FRANCE 3CNRS, Laboratoire de Photonique et de Nanostructures, FRANCE and 4Zhejiang University, CHINA ABSTRACT This paper reports an original microfluidic dye laser based on microdroplets flowing through an on-chip Fabry-Perot cavity. This combination allows fast laser emission at distinct wavelength over a wide bandwidth. The switching time from one wavelength to another, monitored by the droplet production system, can be reduced to the millisecond range. Alternation of rhodamine 6G and sulforhodamine 640 dye droplets have been performed to generate laser emissions at 567 and 625 nm. KEYWORDS: Optofluidics, Droplet, Dye Laser, Fabry-Perot INTRODUCTION Microfluidic dye lasers are compact laser light sources that can serve for biochemical sensing in micrototal analysis systems. Spectroscopy is one main technique allowed by lasers. The emission wavelength is crucial in this application. Monitoring the laser emission is therefore one key point in the development of microfluidic dye lasers. This issue can be addressed by tuning the dye concentration or the optical cavity [1,2]. Another way is to switch from a continuous flow to droplets. Compared to previous works on droplet systems where the droplet itself constitutes the optical cavity [3,4], the new architecture proposed here is based on an integrated Fabry-Perot cavity. The droplet becomes only a vector for the amplifying medium. Our system is thus flexible as there is no specific requirement on optical liquid refractive indexes or on the droplet’s shape.

  • CHAPTER 1 INTRODUCTION 1.1 Literature Review Human Beings
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Universiti Teknologi Malaysia Institutional Repository CHAPTER 1 INTRODUCTION 1.1 Literature Review Human beings are really clever in making use of different kinds and forms of energy. Laser material processing relies on laser systems of desired properties. An inspiring thing in laser processing is the application of ultra-short pulsed lasers. Ultrafast lasers can give scientist opportunities to probe the behavior of matter when exposed to intense radiation and do studies in fields such as astrophysics, general relativity and quantum mechanics. This ultrafast laser currently enable scientist to observe the occurrence of the fastest chemical reaction (Kodymova et al., 2004). This is an advanced technology used for ionizing all material within a small area without any heat or mass flow affecting the surrounding area (Charschan, 1972) and carry out precise micromachining (Liu et al., 1997). This technology is also used to design high density, high-speed communications networks, which an ultrafast laser’s bandwidth is equivalent to millions of telephone calls. Another application is to design compact particle accelerators and generate fusion energy (Lerner, 1998). 2 The ultrafast lasers can also imitate the conditions at the center of stars allowing astrophysicists to experiment with possible ways in which stars form and explode in supernovas. These high powered lasers can focus the power of all sunlight falling on Earth onto a spot a tenth of a millimeter on a side, accelerate electrons close to speed of light and generate pressures hundreds of time those of light and create magnetic fields a billion times of Earth (Lerner, 1998).

  • Regenerative Amplification in Alexandrite of Pulses from Specialized Oscillators
    LLE REVIEW, Volume 34 Regenerative Amplification in Alexandrite of Pulses from Specialized Oscillators In a variety of laser sources capable of reaching high energy levels, the pulse generation and the pulse amplification are physically divided among two or more subsystems. An oscillator generates a low-energy seed pulse with the appropriate temporal and spectral features; then, an amplifier stage increases the seed pulse to the desired energy level. When large gains are desired, numerous amplification stages may be required. Regenerative amplification is an attractive way of limiting the size of the amplifier chain. A seed pulse is injected into a laser resonator that contains a gain medium. The pulse is amplified over many passes through the medium until the gain reaches saturation, and the pulse is then switched out of the resonator cavity. Ideally, the pulse's spectral and temporal characteristics are determined by the oscillator, while the energy output is a function of the regenerative amplifier alone. This technique has been applied to numerous laser media, either flash pumped'-3 or cw pumped,4.s over the last decade. This article describes the use of an alexandrite flash-pumped regenerative amplifier to increase the energy of the output from various specialized oscillators. Regenerative Amplifier Alexandrite is a solid-state lasing medium with an output wavelength that can be continuously tuned over 700-810 nm.6 Due to its very broad pump bands, long fluorescent lifetime (250 ps at 300°K), high saturation fluence (20 J/c~~),~and low stimulated emission cross section (7 x cm2 at 300°K), alexandrite can store large energy densities efficiently.

  • An Introduction to Pulsed Dye Lasers Introduction Light Amplification By
    An Introduction to Pulsed Dye Lasers Introduction Light amplification by stimulated emission of radiation, that is--lasers, have become an important tool in chemistry. Lasers are ideal light sources for spectroscopy, chemical kinetics studies, and light scattering studies of molecular motion. High-powered lasers are finding use as light sources for photochemical synthesis, yielding products not available from other techniques. Dye lasers are an important class of lasers because they can be tuned to a range of wavelengths. The lasers you are probably familiar with, like He-Ne lasers, produce only fixed wavelengths and are therefore not good sources for spectroscopic studies. In this lab you will measure the absorption and fluorescence characteristics of several laser dyes and then set up a dye laser with the dyes and compare the laser emission characteristics. Theory Coherence Laser light is unusual because it is coherent, intense, and formed in a narrowly divergent beam. The light is also monochromatic, that is, the laser produces a narrow range of wavelengths. Let us consider each of these characteristics. Figure 1 illustrates the difference between coherent and incoherent light sources. Incoherent light sources, such as light bulbs, produce many waves but the waves are out of step. Lasers produce light waves that are in step so that the electric and magnetic fields of the waves oscillate in phase with each other. This coherence increases the intensity of the light, in the following way. If the amplitude of a wave is "a," then the intensity of that one wave is a2. The total intensity of an incoherent light source is just the sum of the intensity of all of the waves.
