Managing Inherent and Environmental Thermal Effects On High-Power Laser Systems

A laser will only perform as designed if it emits the correct amount of power or energy and if the beam size is correct for the intended use. The same is true for high-powered lasers, however, the thermal effects that these lasers have on the system add a level of complexity to the application. Some thermal effects are inherent to the system as higher levels of light are applied to components within the system. Other thermal effects come from sources external to the system, such as debris produced from material processing.

Hollow-Core Optical Fiber

Confining light to an air core fiber is not easily done using traditional guidance methods such as total internal reflection. In this presentation we demonstrate guidance in air using photonic band gap guidance and anti-resonant rings. Single-mode hollow-core optical fibers with large cores, resulting in low loss are shown. We also present the attenuation dependence in these fibers and how, using fibers that guide light in air, we are able extend the wavelength range of silica fibers out to the infra-red.

10x Faster Finite Element Analysis of Injection Molded Parts. The Secret? Faster Mid-Surface Modeling and Meshing!

The process of creating midsurface geometry and finite element meshes of injection molded plastics such as automotive interior trim components, aircraft overhead bins, and electronic cases can require extracting dozens of planar and curved midsurfaces, adjoining specific free edges, meshing, and more. Unfortunately with existing finite element pre/post processors, the process can require multiple days to complete.

Phase Change Material (PCM) Heat Sinks: Fundamentals of Operation and Real World Applications

Phase Change Materials (PCMs) Heat sinks provide significant temporary thermal energy storage in an increasing number of military and commercial applications. PCM essentially take benefit from the latent heat required for the solid-to-liquid and liquid-to-gas phase transitions. When properly engineered for power and mission duration, PCM solutions can be used as passive, lightweight, reliable backups or standalone heat sinks.

Analysis of Automotive Adhesives Using FTIR Spectroscopy

In conjunction with SAE The automobile industry is under government regulation to improve the fleet fuel economy. Meeting this regulation will partly be realized by power train improvements, while a significant percentage will be achieved by reducing the mass of the vehicle fleet. Reduced mass will come from the use of lighter materials, notably aluminum, composites and plastics. These materials will require the use of adhesives for joining dissimilar materials, while maintaining strength and managing thermal expansion differences. The use of a variety of adhesives in the automobile industry will grow as new materials are adopted in the vehicle fleet.
