A Must Have For All Medical Laser Personnel! Introducing LIA’s New CMLSOs’ Best Practices Book

Tuesday, February 14th, 2012

ORLANDO, FL., February 14, 2012 — Medical personnel in charge of the safe use of lasers for therapeutic procedures have a valuable new tool to help prevent harm to patients and health care professionals.

The Laser Institute of America has assembled the expert knowledge of leading certified medical laser safety officers in a new book, “CMLSOs’ Best Practices in Medical Laser Safety.” The book compiles the latest knowledge about establishing a medical laser safety program, including laser safety regulations, how to control and evaluate such programs and the duties of LSOs.

Profit from 21st Century Laser Manufacturing – Come to LAM 2012 and learn how!

Tuesday, February 7th, 2012

By: Geoffrey Giordano

ORLANDO, FL, Feb. 7, 2012 — A future in which vital consumer and medical products and parts are made virtually from thin air with just metal or plastic powders and lasers could thrust the U.S. into the forefront of 21st century manufacturing.

Leading the charge in advocating such cutting-edge rapid manufacture and 3D printing is the Laser Institute of America, which holds its fourth annual Laser Additive Manufacturing (LAM) Workshop in Houston, TX on Feb. 29 – March 1. The educational showcase will feature keynote presentations by experts Terry Wohlers of Fort Collins, CO, and Dr. Ingomar Kelbassa of Germany’s Fraunhofer ILT and RWTH Aachen University.

Meet LIA’S 2012 President and Board of Directors

Friday, February 3rd, 2012

 

Reinhart Poprawe, LIA’s 2012 president, has worked in the laser industry and its related organizations for over 30 years. He received an M.A. in physics from California State University in Fresno in 1977. After completion of his Ph.D. in physics (Darmstadt, 1984) he joined the Fraunhofer Institute for Laser Technology in Aachen, Germany where he worked as head of a department for laser-oriented process development.

In 1988 Poprawe started Thyssen Laser Technik GMBH and was the company’s CEO. Since 1996 he has been managing director of the Fraunhofer Institute for Laser Technology and holds the University Chair for Laser Technology at the RWTH Aachen. In 2004 he served as vice rector of Aachen University and currently is a member of several boards in the scientific and industrial organizations, e.g. the AKL Arbeitskreis Lasertechnik e. V. Aachen. He also chairs the RWTH International Board and is the Rectors delegate for China.

Revised ANSI Z136.3 Improves User and Patient Safety

Wednesday, February 1st, 2012

By: Geoff Giordano

 

With more therapeutic procedures moving into private medical offices and homes, the standard regulating the safe use of lasers in health care has undergone a much-needed update to ensure users, as well as patients, are protected.

The revised “ANSI Z136.3 Safe Use of Lasers in Health Care” publication defines the parameters of proper laser use outside the tightly regulated hospital environment. Formerly titled the “American National Standard for Safe Use of Lasers in Health Care Facilities,” the revision released in January includes new guidelines and information on:

•Wavelengths employed in medical environments. While some lasers are no longer listed, at least four new wavelengths have been added.

•The duties of laser safety officers involved with rented or borrowed laser equipment.

•Audit requirements and procedures.

•Clinically relevant terminology.

Cost-Effective Laser Cladding for Corrosion-Resistance

Wednesday, February 1st, 2012

By: Dr. Andrew J Pinkerton, The University of Manchester

The environment continuously attacks our infrastructure in a way that is less spectacular than, for example, earthquakes or hurricanes, but far more expensive. Corrosion affects most surfaces, but especially metallic ones, on a daily basis and costs around 3–6% of developed countries’ GDP to combat. In the US alone corrosion costs are an estimated $276 bn/year, compared to the average annual cost of around $13 billion due to hurricanes. [1,2]

Laser Glass Machining for Consumer Electronic Devices

Wednesday, February 1st, 2012

By Haibin Zhang, ESI.

Due to their excellent strength, chemical resistance, and optical transparency, glass materials are widely used in consumer electronics such as in flat panel TVs, laptops, and hand-held devices.  Small to medium form factor glass panels (3 to 10 inch), in particular, are enjoying a very healthy annual growth of close to 20% thanks to the recent boom in high end smart phones, e-readers, and tablets.

An anatomy on most of these popular gadgets reveals several layers of glass panels:  first is a strengthened piece of cover glass that has extremely high compressive stress to protect the devices from impacts, scratches, stains, and harmful chemicals.  Underneath the cover is a thin layer of glass deposited with two-dimensional ITO patterns (in most cases) to support touch functions.  Display glass such as LCD or OLED modules lies beneath these two layers and provides vivid images and video playbacks at high contrasts.  Different functions of these glass substrates require different designs:  on the cover glass curvilinear and internal features are needed to generate rounded corners, streamlined perimeters, speaker holes, and home buttons.  Touch panel and display module generally only need straight cuts for panel singulation from a mother sheet.
