"Laser surgery is one of the fastest developing procedures in the field of dermatology. This book is a step by step guide to the use of lasers in dermatological practice, covering both common procedures and more advanced techniques. Divided into three sections, the book begins with discussion on conventional laser treatments, followed by chapters on advanced procedures. The final section describes practical aspects including medicolegal issues, complications, and setting up a laser practice. Presented in a systematic, easy to follow format, each chapter is explained with numerous tables, charts, diagrams and clinical photographs to enhance learning. Key points * Step by step guide to use of lasers in dermatological practice * In depth discussion on both conventional and advance techniques * Complete section on practical aspects including medicolegal issues and complications * Includes nearly 300 images, illustrations, tables and charts."

"Dunia penerbangan, baik sipil maupun militer, adalah zona baru yang rentan terkena serangan laser. Jumlah peningkatan angka kejadian yang dilaporkan, menunjukkan ancaman serius terhadap keselamatan penerbangan. Serangan laser pada ketinggian rendah dapat menyebabkan gangguan pengelihatan yang menyilaukan hingga kebutaan mendadak kepada pilot pada fase kritis sebuah penerbangan, seperti saat mendarat atau tinggal landas. Sinar laser yang terlihat maupun yang tidak terlihat juga dapat menyebabkan kerusakan pada mata manusia. Studi literatur ini menyajikan diskusi dan kesimpulan dari sebuah literatur tentang teknologi baru untuk melindungi mata manusia dari ancaman serangan laser."

"Aviation, commercial and military are new area that is suffering from laser threats. With increasing incidents being reported, laser attack present a significant threat to laser safety. Bright visible laser light at low altitude causes a distraction and/or flash blindness to the pilot, during a critical phase of flight like landing or takeoff. It is also possible, that a visible or invisible beam could cause permanent damage to a pilot’s eye. This literature study presents discussion and conclusion of a literature about novel technology for protection of the human eye againstlaser threats in visible range."

"This book mainly addresses the applications of lasers in the manufacture of various industrial components. The technologies presented here have scopes of application ranging from the macro to meso and micro level of components and features. This book includes chapters on the basic and advanced applications of lasers in the manufacturing domain. They present theoretical and practical aspects of laser technology for various applications such as laser-based machining, micro-scribing, texturing, machining of micro-sized channels; laser welding; laser-based correction of sheet metal, i.e. straightening; laser forming; and laser technology for 3-D printing. Lasers have various applications such as the production of powerful lights for illumination or decoration; measurement of velocity (transportation) and length; interferometry; printing; recording; communication; bio-medical instrumentation and pollution detection. A significant body of literature is available on the physics of lasers and types of lasers. However it has been noted there are a few books published on the “applications of lasers in manufacturing domain,” a gap that this book remedies. Gathering contributions by leading engineers and academicians in this area, it offers a valuable source of information for young scientists and research students."

"Characterizations have been performed on single stage Transversely Excited Nitrogen Laser of Blumlein type. Optical cavity arrangement is varied prior to measurement which shows no significant increase in energy on both configurations of inserting a mirror only and a pair of mirror and a quartz parallel plate. Frequency repetitions respond reveals a small drop in energy at higher frequency i.e. 10 Hz by a factor of 20%. N2 flow rate consideration behaves on the similar way like pressure profile. At higher supply voltage maximum energy is shifted to higher N2 flow rate. A similar tendency occurs on pressure curve but with more pronounced maximum energy. Higher supply voltage would shift maximum energy to higher N2 pressure. Other operating conditions have been kept constant. Beam divergence measurement has given 1,87 mrad on vertical direction and 9,32 mrad on horizontal axis. However, beam cross section experiences a -10° tilt against horizontal reference. This may happen due to a slight twist on main electrodes. Measurements on different date have showed inconsistent results. Major cause is suspected on using different N2 cylinder, replacement on the gauge pressure, and crater creation on HV side spark gap electrode."
