High Deposition Rate Laser Cladding – Recent Advancements

By Jari Tuominen, Jonne Näkki, Henri Pajukoski, Tuomo Peltola, Petri Vuoristo

Laser cladding is currently done with 3-6 kW gas and solid state lasers. Components to be clad or repaired are usually small or some discrete regions in larger components. Net deposition rates are typically 1-2 kg/h. In large area coating applications, conventional coating methods such as thermal spraying (HVOF, HVAF) and overlay welding (SAW) prevail due to higher cost efficiency based mainly on high productivity and low capital costs. For applications such as boiler tube panels in power generation and massive hydraulics in off-shore and mining industries, coating properties produced by conventional coating methods are often insufficient.

Challenges of the Medical Laser Safety Officer

By June Curley

As a perioperative nurse working in the operating room of a Level 1 trauma center,   I want to share some of the challenges of implementing a laser safety program and inspire new Laser Safety Officers (LSOs) to develop systems that will assist them with enforcing laser safety compliance.

First, I recommend Medical Laser Safety Officer Training and taking the Board of Laser Safety (BLS®) medical certification exam. Being a Certified Medical Laser Safety Officer (CMLSO®) validates not only our knowledge, but also our commitment to laser safety.  Then, utilize all the available resources: ANSI Z136.3, AORN Standards and Recommended Practices, books on lasers by Dr. Kay Ball and publications referencing eye protection or best practices offered by the Laser Institute of America.

Use of Lasers in Veterinary Medicine

By Kenneth E. Bartels

With the increased use of lasers in veterinary medicine during the past 20 years, the perception that the medical laser is a “tool in search of an application” is out of date.  Initially, the cost of laser technology for veterinary medicine was a limitation, but this impediment did not prevent wide spread use in general veterinary practice, especially when the advantages overshadowed the disadvantages.  Even considering the required learning curve for efficacious use of a new technology, as well as the attendant safety concerns, the use of surgical lasers in both large and small animal veterinary practice increased based, for the most part, on practitioner implementation rather than from objective peer-reviewed research studies originating at academic institutions. That does not mean results of objective controlled and retrospective studies did not appear in veterinary journals, but much of the enthusiasm was promoted through veterinary magazine-type articles often written by veterinarians supported by specific laser companies marketing to the veterinary profession. In addition, many of the laser medicine continuing education venues at international, national, regional and local professional meetings were, and still are, sponsored by respective laser manufacturers.  Without that positive commercial impact, albeit somewhat subjective at times, use of lasers in veterinary medicine would have most likely been limited to veterinary schools and larger general practices. High power (Class 4) lasers have been the devices that opened the door to more extensive use of the technology in veterinary medicine. Continue reading

LIA Offers Convenient CO2 Laser Safety Training for the Rapid Adoption of Lasers in the Medical Field

ORLANDO, FL, November 26, 2012 — As the health industry continues to seek more effective and efficient delivery of care, the CO2 laser plays a vital therapeutic role.  From the hospital operating room to the private aesthetics practice, lasers are indispensable— and properly trained users are more in demand than ever.

The Laser Institute of America, the recognized leader in laser safety resources since 1968, makes using the CO2 laser easier than ever with its online “CO2 Medical Laser Safety Training” course.  Not only does the easy-to-follow Internet-based course allow learning anytime, anywhere, it earns registered nurses two contact hours upon completion.

A Study on Laser Cutting of Textiles

By: Dr. Nukman bin Yusoff

Laser cutting technology is a non-conventional machining which being used widely in many industries. However, the application of this technology in textile industry is still new and yet to be explored. Indeed, nowadays many textile industries are preferred to cut the textile by using conventional way such as discs, band blade and reciprocating knives. As compared to traditional cutting methods the laser cutting offers several advantages such as fast cutting speed, reduced the time consumption, a non-contact cutting and no tool wear.  Thus, using this technology would be more efficient and productive if the right method of laser cutting process is used to replace the conventional cutting methods.
