By James Stewart, CLSO High power lasers are routinely used in entertainment environments as a special lighting effect. Historically such lasers could only be used in situations where the budget, infrastructure, (namely power supply and cooling), and space permitted. In recent years, however, these barriers have disappeared with the proliferation of low-cost solid-state laser light […]

Setting Up a Laser Lab? Avoid the Pitfalls
By Jamie J. King, CLSO The design of a laser laboratory is not only critical to its overall functionality, but more importantly to the safety of those who work in and around it. The safe planning of a laboratory is no accident. From conception to commissioning of the laser, safety must be involved in every […]
FDA’s Proposed Change to the Regulation of Laser Pointers
By Patrick Murphy In October 2016, the U.S. Food and Drug Administration (FDA) put forth a preliminary proposal to declare green, blue, yellow and violet laser pointers as “defective.” Only orange-red and red laser pointers would be allowed to be manufactured, imported or sold in the U.S. This proposal was in response to the thousands […]
Turbine Blade Cladding & Remelting for Single-Crystal Volume Extension
By Irene Alfred, Boris Rottwinkel, Christian Noelke, Volker Wesling, Stefan Kaierle Nickel-based superalloys are used extensively in the combustor and turbine sections of aircraft engines due to their ability to withstand temperatures of up to 1100°C, thereby increasing engine efficiency. The microstructure of single-crystal turbine blades show superior creep and fatigue properties when compared to poly-crystal […]
Laser Applications in Battery Production
By Ruediger Brockmann The proceeding limitation of CO2 emissions by government as well as expected shortage of oil resources worldwide associated with increasing cost for fuel results in a global requirement for alternative mobile forms of energy. The development of these alternative forms of energy is summarized within the Mega Trend E-Mobility. Within this Mega […]
