Laser-Induced Damage to Large Core Optical Fiber by High Peak Power Laser

In this paper we present a study of laser damage to large core multimode glass optical fibers by high peak laser power of up to 175 kW. Fibers samples prepared with polymer coatings having different refractive indices were tested in a two point bend tester while transmitting laser light. The peak power used in the experiment clearly differentiated the performance among the samples. A polymer coating having lower refractive index significantly improves the fiber resistance to bending while transmitting laser. This observation provides important insight into the damage mechanism for this particular failure mode.

Laser Marking for ID and Traceability Within the Medical Industry

Laser marking provides easy and effective labeling for medical devices. The use of lasers to mark surgical instruments has become of greater significance, however, the parameters used in these applications are not always fully appreciated. The medical industry, in particular, has utilized laser technology primarily to mark, weld, and cut medical devices for years. Lasers address the need for microscopic applications: to cut widths measurable in microns, spot welds with heat affected zones barely visible to the unaided eye, and highly resolved biocompatible markings that enable traceability of instruments and implants. In common with other industries, medical devices and pharmaceutical businesses turn to lasers for a one-step, fast, flexible, permanent, and a highly automated marking process.

Using CVD Diamond to Cool Hot Devices

Increasing power densities and decreasing transistor dimensions are hallmarks of many of today’s semiconductor devices, including high-voltage power transistors, laser diodes, and RF power amplifiers. GaN devices, such as power converters for photovoltaic cells and cellular base-station power amplifiers, are further enabling higher power densities in smaller die sizes. Both trends are significantly increasing the thermal management challenge within the chip and surrounding package or module.

UV-Visible-NIR Microspectrophotometer

CRAIC Technologies (San Dimas, CA) has introduced an automated version of the 20/30 Perfect Vision™ UV-visible- NIR microspectrophotometer. This system is designed to be fully programmable with touchscreen controls so that it can automatically analyze microscopic samples with UV-visible-NIR spectroscopy and microscopy. Imaging and spectroscopic analysis of samples can be done by absorbance, reflectance and fluorescence from the deep UV to far into the near infrared.
